@@garrettmcgovern315 read the description of the video. Some people have to mount the black wire to a different screw. Change that and I bet it will work
@4:25 he shows the black wire mounting incorrectly for my rebuilt Denso alternator. The black wire should be attached with the 1st screw he put in. It attaches to the tab that mounts the regulator. This grounds the regulator. The other mounting screw he shows did not carry ground on my alternator. I hope this helps save you the 2 hours I lost troubleshooting. Other than this correction - this guys video was PERFECT and I appreciated the work he spent making it. By the way, this can be mounted while the alternator is installed on the engine.
Thanks Kevin! I really wish I could go back and edit this video. I explained the correction in the description and pinned a comment about the correct. Unfortunately not everyone checks there
@@decentgarage I felt like a fool after re-reading your description! Hopefully this comment stays closer to the top for the next guy. After I took the time to read the comments, I noticed a BUNCH of people had the same issues. Again, thank you for posting this, I just spent $400 on batteries for my fummins swap after a failed Mopar regulator failure. Also, my alternator did not have the clip you removed @3:00. I wonder if that makes the difference on why yours worked and mine did not. Again, Much appreciated.
I did this two months ago on my project truck that was overcharging. After the install it wasnt charging at all. I probably spent 20 hours trying to chase down what the problem was in between fixing other stuff on the truck. Finally saw in the comments that the black wire is supposed to be hooked up to the same spot the transpo bracket is mounted and i did that and put it all back together and now i have 14 volts charging.
I am another one who had trouble with the Transpo after just a few months. I had done the usual external mount regulators that subsequently failed in short order. Installed the Transpo and got about 6 months on it and then it too went south. Finally bit the bullet and put in a one wire. For me it was an easy upgrade as I wanted to bump up from the stock alternator anyway as I charge my trailer batteries while I drive so needed more amps. Pricey? maybe.....I figured I was into 4 regulators that I had to install so time and trouble was well worth putting behind me. Loving your videos.......keep em coming!!!

This was done to my 1991 when I bought it . It was done on a new alternator by an alternator shop receipts were included when I purchased the truck. It was about a year old repair( replacement), About three months after I got the truck I started having problems with the charging system ended up taking it to a competent starter shop here in Ft worth all they do is build starters and alternators and and antique stuff . Make a long story short about a year later I finally put the alternator back stock and the shop owner put a heavy duty voltage regulator on it I will need to get a part #. I am not trying to be critical that does work till it doesn’t but I had a year of hell with that set up every time I thought it was fixed it would go a couple and smoke itself two alternators went through all the wiring etc. it is a very clean California truck to begin with low miles . But now that they finally got a good voltage regulator on it 2.5 years no problems used to average 350 400 miles a week I just retired so not much now. Just my 0.2cenys
Thanks for sharing. Sounds like something wasn't hooked up correctly originally. I've not heard of many people having issues with the Transpo but that's not to say that they aren't out there.

Used this regulator today on my 99' dodge ram with Cummins 24 valve and to get this working you need to have the original blue wire that has 12 volts with engine running and goes into the black connection block and only connect the lower spade onto the lower post on the alternator. It's the one that also has the orange wire from the regulator on. If there is no blue wire then you have to connect a wire with a low wattage light in between on a 12 volts contact with engine running , because the regulator/alternator needs a signal to start charging.
Huge thank you man. Finally solved my charging issues today. My pcm is shot so instead of attempting to rebuild it i bypassed it by installing the transpo, and grounding the bluewire with yellow tracer from the ASD relay. If you do this and it doesnt work for you, try grounding that wire as the pcm may be the issue.
can you explain that again? "grounding the bluewire with yellow tracer from the ASD relay" the wire that runs to the ASD relay the yellow tracer one is gonna go with the bluewire?
@@bammy4182 sorry, to clear it up, its a single wire, blue with a yellow line down it. Comes from pcm, out of the loom, into the ASD relay, cut the wire, and ground it RELAY SIDE. You can tape up the wire coming from pcm Again, its the blue wire with yellow tracer line. Singular wire
91.5 cummins: I ran into a lil issue myself, no charge after wiring the transpo in. I unhooked the black wire and screwed it into the base mount and she works. Now before I wired in the transpo my mopar regulator was working decent. I was getting 14.2 volts (taken from the battery) but had bouncing voltage. Now after installing the transpo I don't have a bouncing voltage regulator but I am at 13.7 volts, even after driving around. I connected all my plugs that come off the alternator into the main harness and all I did was unplug my pigtail that went to the old VR.
@@decentgarage ok sounds good. I have botched wiring where the fusible links were, I have all the midi fuses and the bluesea 150 fuse box too. So hopefully I can clean up the wiring rats nest, remove the old VR wiring, I also plan on removing the grid heaters too.
I have a 91.5 doing the exact same thing (bouncing voltage no matter what I change), I installed the transpo and now have no charge. What black wire did you disconnect and where exactly did you screw it on the base mount? Also did you bend that terminal back and tape it like he described in the video? And any pictures of the setup would help tremendously, thank you!
This voltage regulator will work but if you have voltage regulator failure which happenes quite often on older vehicles, you cannot buy that regulator at your local auto parts. With the Quick Start Voltage Regulator Bypass kit you can.
Good eye. For some reason mine didn't work with how the directions said so i did it like this. Seems like it's 50/50 on what works for people. So try one, if it doesn't work, try the other.
Great video, one thing I just want to mention to you is I went to the post you recommended for the black wire and it wouldn’t charge. I tore it back apart and put the black wire to the mount bolt and it started charging
Nice found this video after local alternator shop installed one, brought it back to them for not charging says “the chip burned out”. Put it back on the truck charges for 2 minutes then stops again. Alternator shop is about a 40 min ride. Removed the cover to find the red wire pinched between the shield and the 8315. I bet this is a common problem with this upgrade
I come to you as a humble 1st Gen’er with gen’er… ator problems. I lost the alternator charge when I fixed the buzzer harness that had melted together causing my ignition power to be constantly on. At that time the truck had an external VR and relay and never had an issue. I replaced the VR thinking that was it and no fix. I got frustrated and ripped out the hacked wiring and restored factory harness. No work. I changed CPS sensor, no work… I bench tested alternator and it passed. I fitted the the Transpo above into alternator and no fix. I have 11.15V going to ignition terminal on alternator but still no charge. I bought a “new” reman alternator and installed Transpo, still no charge. I am baffled. Any ideas or help would be great. I live your channel! Keep killing it.
@@82DieselBunny no, the transpo still needs signal from the cps through the pcm. You may try running keyed power straight to the transpo. Also i know some people who install the transpo and it doesn't ignite until they drive it a few miles. After that it works perfect but for some reason it takes some more draw for that first ignition.
Yes if you have a wire connected that has 12 volts with engine running to the lower post on the alternator. Or if your truck still has the original black block with blue wire at the alternator just connect the lower spade onto the alternator post.
My 1996 12 valve is being transplanted into an IH Traveall therefore I'll have no factory wiring harness or voltage regulator. When I do this conversion do I simply replace the "black block" from the factory harness with a single wire for the power source?
Yes I think it would work when you take a single wire from the ignition (12 volts with engine running) to were the orange wire also is connected on the alternator.
The add on voltage regulator will work but if you have trouble, which older vehicles have, like a regulator failure you cannot buy the regulator at a local auto parts Stores. With the Quick Start Voltage Regulator Bypass kit, you can.
Hello I purchased the unit and installed as per directions and watched your video 3 times to make sure I did it correctly but i still have 11.99 v come out of alt and 12 .44 v at battery the alternator I had tested and was good what did I do wrong the Thank you Martin
Make sure to read the description of the video. About half the people who install this have to switch two of the wires to have it work correctly. It is explained in the description.
@@decentgarage I changed wire locations and it now shows 12.43 battery and alt Do you think my switch on is not holding 12v after the truck starts Thank you
Correct me if im wrong. Im installing this right now in front of me. The black wire is to be installed on the screw that is also mounting the unit as per directions, not elevated screw that you show here. I also doubled checked on a forum site. Not trying to bash.
No worries. I have read and seen it mounted in both places. I would go with what you interpret the directions to say. In my opinion the directions were not as clear as they could have been 👍
@@nickc3207 i went by the installation instructions as they are the ones whom designed the unit. I also found a write up on this install on one of the forums. Works great. I ran into a dead battery once since and it was caused by a ground that was painted over by the P.O. no issues since
So i did this all as you described. But im not 100 percent sure where the power will be coming out of, that i connect to my battery. On the top side of my little black box, i have 4 wires comeing out 2 bigger black ones, and 2 smaller bluish green ones. And i dont seem to get a current out of any of them.
Hope you're still getting posed on this. I have a 91 Non-IC W350. I believe it came stock with an external voltage regulator. My question is, do I have to disconnect that external unit, when I install the 8315? Please let me know.
Just finished the install, per this video. I'm getting not much in the way of charging. I revved it up, but found no difference. Do I need to do anything with the lines to the external voltage regulator I disconnected?
Yes. I appreciated this video, which made it easy. Now, flash forward. I decided to "restore" to the original set up, after not getting a charge. Broke the bent lead off doing so. Referred to the instructions, to get the 8315 working. I have both terminals on the field reading 12 volts with ignition in "on" position. After switching the green and orange wires and getting the same result, I'm starting to look at the "'one wire alternator" option. I know. Sh&t show, and I didn't include everything. Should have seen me on the Cummins Forum, recovering from a KDP. Think two of the moderators gave up on me. Any ideas? @@decentgarage
Will this work on the 90, a truck that doesn’t have a PCM? I recently replaced the alternator, the VR, then added a relay behind the VR to simply switched battery volts. That worked good for a week and I had to install yet another VR today.
hey i need some advice so the stock wiring harness what wire is power i have a 1991 that the connectors broke i have a black wire and a black and white one that was on there and a green and blue one
My 89 12V is overcharging. After installing the transpo im assuming its ok to keep the stock external regulator installed? Or do i need to wire it out?
Thanks again for the video and info. Installed the transpo today following your video EXECPT I connected the black transpo wire to the same point the regulator mounts. Installed and its now charging at 14.2V. Seems to have fixed the issue. -Drew@@decentgarage
Wiring question. What do you do with the green and white wires from the trucks wiring harness that normal attach to the rear posts on the alternator? Are they used or just taped and put out of the way? Another question. What size are the 2 little nuts on the rear of the alternator where the little factory wires attach? Mine are gone
Does this part go bad? I've been having a hell of a time with my alternator recently, took it off to replace it but mine has wires coming from inside it the new ones don't, truck charges but barely, could I just need to replace this regulator?
So I'm thinking of doing this to my 98. Only difference I see is I don't have a wire going from my output post to my field posts. Do I need to run 12v to the field posts for it to work and if so should it be keyed or is it ok to have it hooked up all the time with the output wire to the battery
I passed on this unit, because the amazon reviews are so bad. Also, it may be tidy to have it internal, but it is also a lot harder to replace on the fly if it goes bad, vs an external voltage regulator you can keep an extra in the glove box and cob it together on the road.
How about a 91 w250 5.9 gas engine.....did try putting a external voltage regulator with sprate wires and old 79 ramcharger alternator only 60 amp....and it's not charging stable...put a little load on it and it discharging..unit I turn the turn sign off.....I'm eventually ditching out the computer it's junk ..have a 70-87 ignition system...in it now to run it....will put a complete wiring harness in it.....
Will this work on my 1990 nonintercooled cummins. I watched your video with the ADS relay trying to figure out why my truck is not charging, but these earlier trucks don’t have those relays. Well at least not on the fender. I believe these come with an external regulator from factory. Do you think there would be a problem if I eliminate that.
@@decentgarage update: I installed the transpo 8315 the way you showed and still no charge. I read up on the comments and switched the black wire to the mounting screw and voila my truck is charging again! Thanks for the video and Info man! It does work on the non intercooled trucks!
@@davidoropeza2249 thanks for checking the description! It's weird that some trucks work with it wired like mine and some work with those wires switched.
@@roberta.6295 There is the spot I mounted mine to (it worked) and there is also a screw less that an inch from where I mounted mine and that's where other people have to mount it to
Did you’re CEL light come on after? It is charging and doing its thing. But now I have a CEL on… I checked it and is showing 41 Generator field not switching properly, did you have this issue?
Great video. Very instructive. Have you considered installing a Borgeson steering shaft? I think I spelled it right. I've heard good things about it. I believe there are 2 types. I've thought about putting one on my truck, but haven't seen a good install video. Try looking into it. Like I said, your videos are very instructive and if you believe it to be a good upgrade, it would be nice to see how you would install it. Thanks.
Does one of the wires have a 12 volt reference coming from the battery? Or is it supposed to? I installed one of these after previous owner did a bunch of hack job wiring and had tried to wire in an external regulator. Now I'm trying to fix it all
I have a 91.5 first gen that would eat regulators. They would either overcharge or not charge at all. I checked every ground connection to no avail. I purchased the heavy duty adjustable regulator on ebay, this was over 10 years ago. Moved it from the firewall above the exhaust manifold to the drivers inner fender. Set it at 13.9 volts and it is still working today. I purchased a second as a backup and it is still in the glove compartment. It also has the original alternator. Stay Ultra Maga!
@@decentgarage watched it, cut the blue wire out and wired it directly to my alternator, no charge so I tested continuity for fusable links and still no charge:(
@@decentgarage I don’t think I seen anything about a black wire, which black wire and was it in this video or another? Since I have continuity with fusible link I’ll probably move to checking ASD, tracing the ignition wire to check for power and that will probably be where I end it because I don’t have a position sensor on this one
@@decentgarage right on thank you, I jus have a 89 1st gen that needs some up grade and a 93 1st super cab that needs work but I’m not really asking anyone.. I’d like to do it myself but I have no time.. but thank you for responding
I had an external regulator and it had the overcharging issue. I swapped it to the transpo internal regulator and now I have the no charge issue. I've replaced the cps, alternator, and checked the relay which are all good. Any thoughts?
Yes I tried the wire both ways and still nothing everything else works great. I double checked everything I replaced and have found nothing that would cause it
I did and the only thing I saw was possibly the ecm, but I'm almost certain it's good. Do you know of anyway to test it or is it something I'd just have to bite the bullet on and replace?
I'm having trouble with cold starts? My 12 valve ve pump will not idle until it warms up....I literally have to hold the throttle for 20 minutes? And then it mysteriously idols perfect! Any help would be appreciated.
Sounds like an issue with the ksb. Make sure the wiring to that is functioning properly. It basically advances the timing when it's cold to help it idle. Google 1st gen ksb and see what you find.
Yes, this is your new regulator. Make sure you read the description of the video if it doesn't work. About half of people have to hook the black wire to a different spot than how I show it in the video.
Did you watch my two other videos on this. When i installed this on my truck it still wasn't charging. I have two videos going through diagnosing that issue 👍
@@decentgarage well it worked at first then I realized I put that black wire on the wrong screw that was a little bit deeper on the back of the alternator do you think that burned out the new part from amazon I put on? I suck at wrenching I appreciate the help thanks
You are no longer on and external regulator but on intercooled trucks it is still controlled by the pcm. If you want to avoid the pcm completely you can go with a 1 wire alternator
@@decentgarage so if I get a one wire alternator I can bypass the pcm? It is a 93 and I’ve been told that voltage regulator is bad, when I replace the alternator a year ago it fixed it but the now I’m not getting charge again

My 92 2500 4 wheel drive Will like this idea.
Bought my truck the fall of 92. It just goes to the summer show and shines
Make sure to read the video description and some of the comments on this one 👍
My 1996 12 valve is being transplanted into an IH Traveall therefore I'll have no factory wiring harness or voltage regulator. When I do this conversion do I simply replace the "black block" from the factory harness with a single wire for the power source?
Yes I think it would work when you take a single wire from the ignition (12 volts with engine running) to were the orange wire also is connected on the alternator.
Will this help with over charging issues?
What about flickering lights ? Head lights cut off while driving
Check your grounds
The add on voltage regulator will work but if you have trouble, which older vehicles have, like a regulator failure you cannot buy the regulator at a local auto parts Stores. With the Quick Start Voltage Regulator Bypass kit, you can.
Hi thank you to show the good work will work for 06 Dodge Ram 2500??
I do not know if this will work on a newer Cummins.
This is why you're the man
Just trying to catch up to you Bryce!
Hello, Thank you for your advice. Do you have disconnect the external regulator plug after you in installed the internal regulator?
I installed the internal voltage regarlator fixed my problem
Hello
I purchased the unit and installed as per directions and watched your video 3 times to make sure I did it correctly but i still have 11.99 v come out of alt and 12 .44 v at battery the alternator I had tested and was good
what did I do wrong the
Thank you
Martin
Make sure to read the description of the video. About half the people who install this have to switch two of the wires to have it work correctly. It is explained in the description.
@@decentgarage
I changed wire locations and it now shows 12.43 battery and alt
Do you think my switch on is not holding 12v after the truck starts
Thank you
It’s your black wire. Change it’s location to shiny copper gold screw
Correct me if im wrong. Im installing this right now in front of me. The black wire is to be installed on the screw that is also mounting the unit as per directions, not elevated screw that you show here. I also doubled checked on a forum site. Not trying to bash.
No worries. I have read and seen it mounted in both places. I would go with what you interpret the directions to say. In my opinion the directions were not as clear as they could have been 👍
I noticed the same thing. Did you end up doing the lower screw per the instructions or the higher like decent garage?
@@nickc3207 i went by the installation instructions as they are the ones whom designed the unit. I also found a write up on this install on one of the forums. Works great. I ran into a dead battery once since and it was caused by a ground that was painted over by the P.O. no issues since
Tearing mine back down tomorrow to see changing the black wire attachment point makes it work.
So i did this all as you described. But im not 100 percent sure where the power will be coming out of, that i connect to my battery. On the top side of my little black box, i have 4 wires comeing out 2 bigger black ones, and 2 smaller bluish green ones. And i dont seem to get a current out of any of them.
Hope you're still getting posed on this. I have a 91 Non-IC W350. I believe it came stock with an external voltage regulator. My question is, do I have to disconnect that external unit, when I install the 8315? Please let me know.
Yes, this does away with the external regulator
Just finished the install, per this video. I'm getting not much in the way of charging. I revved it up, but found no difference. Do I need to do anything with the lines to the external voltage regulator I disconnected?
@@s.landin4225 did you read the description and make sure you have the wiring done according to what I wrote in the description?
Yes. I appreciated this video, which made it easy. Now, flash forward. I decided to "restore" to the original set up, after not getting a charge. Broke the bent lead off doing so. Referred to the instructions, to get the 8315 working. I have both terminals on the field reading 12 volts with ignition in "on" position. After switching the green and orange wires and getting the same result, I'm starting to look at the "'one wire alternator" option. I know. Sh&t show, and I didn't include everything. Should have seen me on the Cummins Forum, recovering from a KDP. Think two of the moderators gave up on me. Any ideas? @@decentgarage
Uh....just read the description. I'll get back to you. Here's hoping!
Will this work on the 90, a truck that doesn’t have a PCM? I recently replaced the alternator, the VR, then added a relay behind the VR to simply switched battery volts. That worked good for a week and I had to install yet another VR today.
hey i need some advice so the stock wiring harness what wire is power i have a 1991 that the connectors broke i have a black wire and a black and white one that was on there and a green and blue one
My 89 12V is overcharging. After installing the transpo im assuming its ok to keep the stock external regulator installed? Or do i need to wire it out?
I would just get rid of it. Also, make sure to read the description and comments on this video!
Thanks again for the video and info. Installed the transpo today following your video EXECPT I connected the black transpo wire to the same point the regulator mounts. Installed and its now charging at 14.2V. Seems to have fixed the issue. -Drew@@decentgarage
@@drew.blanks nice! Yeah I didn't mount the black wire correctly
How can I find the part ( transpo)
@@decentgarageI saw it soon I asked 😅
Wiring question. What do you do with the green and white wires from the trucks wiring harness that normal attach to the rear posts on the alternator? Are they used or just taped and put out of the way? Another question. What size are the 2 little nuts on the rear of the alternator where the little factory wires attach? Mine are gone
Is this applicable on a 94 Dodge ram truck 5.2.appears easier than external regulator.thanks Robbie
Does this part go bad? I've been having a hell of a time with my alternator recently, took it off to replace it but mine has wires coming from inside it the new ones don't, truck charges but barely, could I just need to replace this regulator?
I have heard of some of the solder points coming undone on them.
So I'm thinking of doing this to my 98. Only difference I see is I don't have a wire going from my output post to my field posts. Do I need to run 12v to the field posts for it to work and if so should it be keyed or is it ok to have it hooked up all the time with the output wire to the battery
I passed on this unit, because the amazon reviews are so bad. Also, it may be tidy to have it internal, but it is also a lot harder to replace on the fly if it goes bad, vs an external voltage regulator you can keep an extra in the glove box and cob it together on the road.
Will this only work on certain alternators
It should work with any alternator for a 12 valve cummins.
a video how to plug a tach on a first gen will be cool
Agreed. I'll see what I can do. Really depends on the year as 92 and 93 have a plug in the stock harness for it.
How about a 91 w250 5.9 gas engine.....did try putting a external voltage regulator with sprate wires and old 79 ramcharger alternator only 60 amp....and it's not charging stable...put a little load on it and it discharging..unit I turn the turn sign off.....I'm eventually ditching out the computer it's junk ..have a 70-87 ignition system...in it now to run it....will put a complete wiring harness in it.....
Transpo 8315 internal Voltage regulator for a Chrysler Alternator.
Will this work on my 1990 nonintercooled cummins. I watched your video with the ADS relay trying to figure out why my truck is not charging, but these earlier trucks don’t have those relays. Well at least not on the fender. I believe these come with an external regulator from factory. Do you think there would be a problem if I eliminate that.
This is a great question that i don't actually know the answer to. I would think that it would work but I'm not confident in that answer
@@decentgarage update: I installed the transpo 8315 the way you showed and still no charge. I read up on the comments and switched the black wire to the mounting screw and voila my truck is charging again! Thanks for the video and Info man!
It does work on the non intercooled trucks!
@@davidoropeza2249 thanks for checking the description! It's weird that some trucks work with it wired like mine and some work with those wires switched.
Does this work the same with Gas? Or is the system different?
I would guess it would work but I cannot confirm
Good video, thank you as the connections were verified by this video. Nice job.
Make sure you also read the description of this video. Many people have to mount the black wire to a different spot
@@decentgarage Do you know what the alternet spot is as mine is not working?
@@roberta.6295 There is the spot I mounted mine to (it worked) and there is also a screw less that an inch from where I mounted mine and that's where other people have to mount it to
Can you please tell me if you a source for either a replacement PCM or a company that restores them?
Is there something like this for a gasser alternator
I do not know the answer to that 🤔
The stock wire block was cut off mine
Do I connect the blue wire or green wire to the lower stud at the end of the video?
The blue wire. I believe I talk about that in this video as my stock harness was cut off as well
th-cam.com/video/NUEB0vHQmWQ/w-d-xo.html
What will this do to pcm , that fails to charge?
Did you’re CEL light come on after? It is charging and doing its thing. But now I have a CEL on… I checked it and is showing 41 Generator field not switching properly, did you have this issue?
does this fix make it charge without pcm cause i have a cummins in a chevy and am wordering if this will work for me
This fix still requires the pcm. If you don't have a pcm you need to go with a external regulator or a 1 wire alt
I want to use external voltage regulator, but I don't think I can use it on a 2011 town and country?
Great video. Very instructive. Have you considered installing a Borgeson steering shaft? I think I spelled it right. I've heard good things about it. I believe there are 2 types. I've thought about putting one on my truck, but haven't seen a good install video. Try looking into it. Like I said, your videos are very instructive and if you believe it to be a good upgrade, it would be nice to see how you would install it. Thanks.
I've got one on both the trucks at this point. I'll see if I can make a video on one at another time.
cant really see what wire your deleting at the end i just cut mine off with a die grinder cutting wheel
Does one of the wires have a 12 volt reference coming from the battery? Or is it supposed to? I installed one of these after previous owner did a bunch of hack job wiring and had tried to wire in an external regulator. Now I'm trying to fix it all
Mines still not charging
Mine won’t charge if I connect the black box back to orange wire but will work if I put it to 12v
How do i install the voltage regulator in a 1991 dodge ram 150 5.2 leter please help i need my truck to work
I have a 91.5 first gen that would eat regulators.
They would either overcharge or not charge at all.
I checked every ground connection to no avail.
I purchased the heavy duty adjustable regulator on ebay, this was over 10 years ago.
Moved it from the firewall above the exhaust manifold to the drivers inner fender.
Set it at 13.9 volts and it is still working today.
I purchased a second as a backup and it is still in the glove compartment.
It also has the original alternator.
Stay Ultra Maga!
I did this on my 1989 exactly as you did and now I’m not getting any charge from the alternator, thoughts?
Read the description of the video 👍
@@decentgarage watched it, cut the blue wire out and wired it directly to my alternator, no charge so I tested continuity for fusable links and still no charge:(
@@journeyjackson7058 did you see the part about where the black wire mounts though? I showed it incorrectly in the video.
@@decentgarage I don’t think I seen anything about a black wire, which black wire and was it in this video or another? Since I have continuity with fusible link I’ll probably move to checking ASD, tracing the ignition wire to check for power and that will probably be where I end it because I don’t have a position sensor on this one
@@journeyjackson7058 yeah read theough the comments and the description.
Hey great video but i have a question can i do this on a 95 dodge cummins because i have problems of charging
Yes, this will work on any 12 valve cummins (89-98)
Awesome, you take outside projects to work on ?
I do not. This truck is a very very rare exception
@@decentgarage right on thank you, I jus have a 89 1st gen that needs some up grade and a 93 1st super cab that needs work but I’m not really asking anyone.. I’d like to do it myself but I have no time.. but thank you for responding
@@AzMurphy2022 you'll get around to it. But let me know if you have questions
@@decentgarage sure will ask if i need to thank you
Which screws?
I had an external regulator and it had the overcharging issue. I swapped it to the transpo internal regulator and now I have the no charge issue. I've replaced the cps, alternator, and checked the relay which are all good. Any thoughts?
Did you read the video description? Some people have to switch two of the wires. Is everything else working? Cruise? Ac? Tach? Grid heaters?
Yes I tried the wire both ways and still nothing everything else works great. I double checked everything I replaced and have found nothing that would cause it
Did you watch my other video on diagnosing this? Mine did the same thingp
I did and the only thing I saw was possibly the ecm, but I'm almost certain it's good. Do you know of anyway to test it or is it something I'd just have to bite the bullet on and replace?
If you have working ac, cruise, tach, grid heaters your ECM is good
The screws are m4 x6 .7 pitch if you guys also strip yours and need to replace them🤙🏻
Does this work with an over charging issue?? I’m hitting 18 volts
Yes, but also go watch my other two videos on the overcharging issue I was having as well.
Will this work on 2nd gen?
I'm having trouble with cold starts? My 12 valve ve pump will not idle until it warms up....I literally have to hold the throttle for 20 minutes? And then it mysteriously idols perfect! Any help would be appreciated.
Sounds like an issue with the ksb. Make sure the wiring to that is functioning properly. It basically advances the timing when it's cold to help it idle. Google 1st gen ksb and see what you find.
The ksb is located right under the injection pump
Yes I've pulled the sensor ,and works fine? Even pulled the stop sensor, it's fine? Your channel is Awesome! I even replaced the temp sensor?
How cold are we talking?
@@decentgarage 30 degrees it's got me stumped, I'm going to check the indexing but why would it run and idle fine when warm?
Does this work on gasser 1st gens too
I am not sure on that...
Mines still only at 12 ish volts, anyone got any more suggestions?
I replaced the knock sensor, alternator, cleaned up the fusible link
Make sure to read the video description. I hooked up the ground wire wrong in the video
@decentgarage yeah i put it in the right spot, still nothing. I wanna try replacing the ASD relay, it's the last thing I can think of aside from pcm
will it work on 2011 town and country
I don't know the answer to that...
Just installed this , do I disconnect the external regulator?
Yes, this is your new regulator. Make sure you read the description of the video if it doesn't work. About half of people have to hook the black wire to a different spot than how I show it in the video.
I just did this on my 91 first gen and it won’t charge any thoughts
Alrighty I got it installed will this cause it to throw a check engine light?
Well shit now the check engine light went away and it’s not charging again ?
Did you watch my two other videos on this. When i installed this on my truck it still wasn't charging. I have two videos going through diagnosing that issue 👍
@@decentgarage well it worked at first then I realized I put that black wire on the wrong screw that was a little bit deeper on the back of the alternator do you think that burned out the new part from amazon I put on? I suck at wrenching I appreciate the help thanks
My check engine light is on after doing this too, did you find and answer?
@@tyashcraft9496 I think I ended up just having a bad ground if I remember right
So in other words you no longer are connected to an external regulator or the trucks computer?
You are no longer on and external regulator but on intercooled trucks it is still controlled by the pcm. If you want to avoid the pcm completely you can go with a 1 wire alternator
@@decentgarage so if I get a one wire alternator I can bypass the pcm? It is a 93 and I’ve been told that voltage regulator is bad, when I replace the alternator a year ago it fixed it but the now I’m not getting charge again
@@coltnoah4779 there are many more things you have to do to completely bypass the pcm. I would do this Transpo and see what happens. I have a few other videos from a month or two ago of diagnosing charging issues
@@decentgarage
So if there telling me I have a bad voltage regulator but every time I buy a new alternator it fixes it what do you recommend I do from there, I heard that getting a new pcm is a real pain in the ass. I have a 93 intercooled
@@decentgarage is it possible the voltage regulator is making the alternators take a shit?
What about flickering lights dash lights every lights head lights cut on and off while driving
Check your grounds
Bro- please take this video down . I didn’t read your note and I lost an hour having to pull mine apart to move the black wire to the proper screw. People like me assume that you are posting a tutorial on fixing the charging system not a failure . Thank you
What screw does it go on literally just pulled mine back out to fix this lol
Does this work on the gas 360 tbi I hav a 91 but alternator looks different
Just did this on my 1990 w250 and it still charges at 19v what should I do
Make sure to read the description of the video. I bet you need to switch where the black wire is mounted.
@@decentgarage is it possible I installed a defective one
@@decentgarage I know my external regulator is still good and I put a ton of grounds in so I’m lost
@@DG-wj6ks did you try switching where the black wire is mounted?
@@decentgarage not yet I just did it as the way the video showed, where else can I put it?
After I installed the transpo the battery gauge stop working and also speed goes up and back. The truck works fine. Any ideas?
Sounds like a bad ground. Make sure all your grounds are clean and secure.
@@decentgarage thanks man
How I get that done to my mitsubishi alternator
Not sure on doing this on other alternators...
@@decentgarage I really want to do this one
So what’s the deal ? Everything should just start charging again??? Nothing else needs to be done?? Thanks so much
In most cases this should have it charging again.
Where did that little orange piece come from? I didn't see it come out and it just appeared all of a sudden.
What little orange piece? Can you give me a timestamp?
@@decentgarage 6:00 It wasn't there when videoing then it was and you put a comment that you would put it back in later.
@@tobylou8 gotcha, that is a little rubber piece that is on the factory alternator under the cover right on the center phone piece.
Anyone else run into the problem of the truck not turning off when turning the ignition off after this instal? Truck is charging now but it won’t turn off
You didn't say why this is needed?
U own a 1990 dodge w150 4x4 it wont charge
This should work but make sure to read the description of the video 👍
