You might have blown that fuse during alternator replacement unknowingly. Remote sense alternators require specific steps to be taken during removal/replacement to avoid damaging the internal resistor. If this happens due to improper removal or installation they will also not honor a warranty replacement on the part. Just fyi, happened to run across your vid & it came to mind. Check out the video from Borg Warner below if you ever have to perform this procedure again, it might save you a headache or two? th-cam.com/video/bzJ0-r_QE4o/w-d-xo.html
Thank you, this video really helped me. I been dealing with this problem over 2 years. I went to 4 different mechanics and burnt out 2 sets of batteries in a years time. Both sets ended up swollen. I had a major loss of power to the Transmission and its been driving me crazy. But this was definitely the problem. Once I pulled that fuse it was broke. I replaced it and went from 14.8 volts to 14 volts also my front dome light and dash lights would cut off after 3 or 4 minutes after hearing that low voltage alarm which I didn't know what that sound was for. But now the problem is resolved. Thank you so much.
I want to say thank. My inverter just started going crazy I looked down voltage at 16.2 my head went down found this and in mind of pulling over fixed. Thanks again
i love youuuuuu save my asss!!! i replace the alternador on a Petro in Tennessee!!! i was crazyyy looking why is overcharging until i see this beautiful video thank youuuuu
And that fuse being blown is exactly why as a mechanic, expecially on a freightliner advise never to use a power probe. A volt meter would have told you the resistance was messed up. I always pull fuses out to test them. Power probes will send to high of voltage to modules. If you want to see smoke coming from a module use a power probe. Most companies that maintain fleets have banned their mechanics from using them. No joke. They can cause thousands of dollars in damage if not used absolutely correct. Can't go wrong with a trusty volt ohm meter.
It's now 9:30pm and I have been thinking of any reason why my volts are at 14.7 ever since I replaced a starter yesterday. Watched this video. Went to check that fuse and sure enough it is burnt. Except my truck is a 2012 and it is a 5 amp fuse on the very top of the fuse box that is located under the brake valve behind all the air lines. Thank you for the tip sir.
Got a 2018 cascadia been having this same issue recently have went through 4 sets of batteries voltage fluctuate when driving 14.5 on up hits 15 goes back down and keeps fluctuating was driving the other night driver side light went out then kept flashing coming on n off did my 10hr woke up and the batteries were cooking could smell the sulfur took to TA had to get a new set of batteries AGAIN 4th time of course they do a basic check of starter and alternator no problem found especially with the alternator since I just got a new one last year in June...... going to buy a box of fuses and change this shit myself hopefully it'll fix the issue I'll update when it's done
The dealers and all the mechanics that I asked told me that 14.7 volt was ok and not to worry about. All those guys are real morons,that's the reason I am doing all the services on my trucks myself for years now. Thank you very much for the help.
@@joefeng23 I did change the alternator. I bought one in junk yard for $75.00 The new that I bought cost me $650.00 and it was defective. The new parts are coming from Mexico and most of those parts have a very short life of service and a lot of them are defective.
Hello, I've my batteries cage going up to over 16 , ive connected the bottom bolt terminal and top one on side of alternator, now cage moving between 14 to 14.6 .after running truck on idling. Should i keep truck running for some time?
Thank you for the Video I have 1998 Fld 120 Freightliner series 60 engine I just made oil change on it and I see high voltage over 18 instead of 14-15 volts.... any reason why? Please I need your help ... Thanks 🙏
Sorry I didn’t see this earlier. By now you have found out that the rectifier on your alternator has blown. Replace the alternator of find an alternator/starter repair shop and have it fixed. Good luck to you.
You can also jump the Battery + output on the alternator to the sense terminal. In case the sense wire is damaged somewhere and just want to bring the voltage down.
I have been to a couple of mechanics and spent over 700.00 and now it sits at Freightliner for a week until they can diagnose it. I am going to the truck and see if I have the same fix. I will update this afternoon.
Excellent information of which I am so grateful for. However, the sound is very , very bad through a laptop. You appear to have a lose connection on your microphone. I wish you could re do the video, or the sound. Thanks again for your wonderful contribution. It is these types of videos that are most helpful to the Australian Outback Truckers tv show. well done... just repair your microphone lead please...
Hey buddy i have a 2011 cascadia same engine and i have 15.5 v on dash bord so i try to check the fuse but every time i put a new one just blow right away any tip?
I have a 09 cascadia dd15 and I bought 4 new batteries and after 4 days being sitting it drain my new batteries no juice on them what can possibly be any areas where I can start? thanks
Don't buy a Cascadia. I'm on my second Columbia. I hate to say it but not a Cascadia fan. If you get one, find a sixty series to go in it. Throw the seats away. Good luck. That shit is far more complicated than it it needs to be.
My truck is losing voltage upto 11.8 volts. No problems in starting. Battery check passed. When mechanic checked alternator he said it's not faulty but i saw volts on his meter was around 17.8 After driving around 30 miles when i restart my truck voltage stays at 14.2 with no problem. Idk what's causing this issue. Definitely will check this fuse. Cascadia 2013
You get it figured out @AS? I'm having the same issue, 2012 Cascadia going down to 11.7 volts on the dash, everything has passed. When cranked the alternator is pushing 14.3 volts and inverter the same reading but the dash will show 12 volts.
Thank you so much. I’m having this issue. My battery gauge was going crazy like high voltage, now my truck is having a low voltage and it wont start anymore due to low voltage. Now its about 1:00am i will check that fuse in the morning and i will let yo guys know whats up. Thank you.
exforbrian1 I did what you did and it worked for about an hour than the Voltage started skyrocketing again. Turned out that all my maxifuses were also slightly burnt and one mini fuse was completely burnt out. Too bad I had already installed a new Alternator prior to watching this video. But that's okay because now I have a spare Alternator, not to mention the Knowledge I gained. I always thought a fuse was either good or bad; never in between.
My new brand new alternator was overcharging...... until I found this video😉 I have a 2011 Cascadia and the fuse is located inside the PNDB on the firewall. Great video!
My LVD fuse burns every few hours and my battery voltage drops to 12.5. I replace the fuse and it start charging normal. Also my ac stops working when the lvd fuse burns. Anyone know what it could be? Im guessing the low voltage module but not sure

Did it cause your truck AC to shut down power or through any samcab codes

What year is your truck having same issue with my 2018 Cascadia
Thank you! I was charging 16-17 volts and this was my problem. Though mine is a ‘15 with a Cummins and it was 5 amps an in a small box on the firewall

Mine is 14.6 now
What did you do about it? Replace the alternator?
@@joefeng23
I did change the alternator.
I bought one in junk yard for $75.00
The new that I bought cost me $650.00 and it was defective.
The new parts are coming from Mexico and most of those parts have a very short life of service and a lot of them are defective.
@@joefeng23
You must change the alternator asap before it causes you major problems on your truck.
14.6 is absolutely high.
Hello, I've my batteries cage going up to over 16 , ive connected the bottom bolt terminal and top one on side of alternator, now cage moving between 14 to 14.6 .after running truck on idling.

Yeah I just put new Alternator..
And the problem fixed...
I really appreciate!
You can also jump the Battery + output on the alternator to the sense terminal. In case the sense wire is damaged somewhere and just want to bring the voltage down.
I disconnected the sense and put in a jumper. Was running 15.0-15.5, now I’m at 14.22 on the alternator and the same at the batteries
Thanks,that you helped me solve the problem. Puno vam hvala za sugestiju.

Sorry about the sound! I wish I could fix it but I’m a better driver then you tuber. Lol
This video just save me a major headache
Nice. My truck is spiking voltage. I checked with an ohm meter on my cascadia. Mine has a Cummins Engine though. Didn't find any bad.
What is the normal voltage for a cascade?
Thank you so much bro, you save me a lot of time and money!!!!
Thank you brother, you really helped me
Hey buddy i have a 2011 cascadia same engine and i have 15.5 v on dash bord so i try to check the fuse but every time i put a new one just blow right away any tip?
You’re wiring
What was the fix
What was wrong ? I have the same issue.. alternator replaced fixes the v spike but still blows fuse
I have a 09 cascadia dd15 and I bought 4 new batteries and after 4 days being sitting it drain my new batteries no juice on them what can possibly be any areas where I can start? thanks
Does the code have to be cleared or does it go off once fixed?
Good video keep up
How about on a 2018 having same issue?
Thank you! Had a fuse blown
Thank you so much for this tip!!!

Thanks. Saved me a day.
Thanks I’m having that high voltage problem with my Peterbilt service don’t seem to know nothing so I guess I try what you just showed Thanks Again
Did you fix your problem with your Pete? Having the same issue with my 587... High Voltage 15.6...

Could be the low voltage module.
Did you find out
Great content ...worst sound , ur voice can be barely heard, but thx for posting it, very useful
Great job thanks
Thank you sir... I'm having this issue right now

Arnold Ramos where are the maxifuses? I have a Cascadia 2010. Thx
How about a 2018 having this issue?
Same here
Man I have high voltage on my 2015 International pro star. My "mechanic" still can't figure it out.
Did you fixed, what was it I'm having same problem in the middle of nowhere same truck
have your mechanic watch the delco remy video about remote sense and bypassing it
You don't check voltage with an ohm meter you check resistance and continuity
Power probe do both, check Volts,continuity + u can send either power or ground
My LVD fuse burns every few hours and my battery voltage drops to 12.5. I replace the fuse and it start charging normal. Also my ac stops working when the lvd fuse burns. Anyone know what it could be? Im guessing the low voltage module but not sure
Ed Edo I would say try using a little bigger fuse. If it calls for 10 amp then go 15 amp. But there is something wrong.
You have a ground wire loose.
Low-key. Will a loose ground wire cause a surge in Voltage? Mine surges up to 15.0+
Jr Villarreal yes mine jumped to 15 also and set my inverter off. My inverter thru a lup code and that means i had a loose ground.
@@lowkey6679 I figured it out... It was my alternator... It was over charging my system. $725 dollars later it's working fine.
I'm hoping this is my problem..I've done everything else...thanks
Eric Scott did that work out for you?
Your audio volume is horrible
jose amador thanks. I tried to do this but I’m an amateur and I don’t know why it’s that bad. But I hope you were able to use the info. God bless
