I have done 40 years of soldering and repairing PWB'S. Clinton, you did a mighty fine job. 😊 Awesome! 😊 I still have all my soldering tools and solder!
Hi Clint you keep saying your no expert but from what I’m seeing you have more diagnostic skills than anyone from our local Deere dealer a testament to your dads teachings over the years 👍 you look for the problem not simply throw parts at it
20:28 I’m 77 now still remember doing jobs similar to this. Happened to have a customer bring in a board with the same thing a couple bad capacitors. It was a quick repair and as I was writing up the paperwork he says Damn expensive for no more than you did. My reply was , You wanted an in a hurry, drop everything emergency repair. You’re paying for my knowledge not for my time. If it was that easy everyone could do it. Great work Clint 😁👍
Clint, You should use rosin core solder on electronic devices not acid core. That's for plumbing (copper fittings). Acid core solder will eventually corrode the traces and lands on the circuit board. Great video as always.
Clint, if you can find some conformal coating, that is what the whole board is coated with, and after you are done soldering with the rosin core solder, clean everything with alcohol and then put the conformal coating on the area where you did the repair. That should make for a long-lasting repair.
This is correct advice Clint. I've been working on electronics for 50 years. Acid flux is for plumbing. Acid free or rosin core is for electronics. Your local radio shop can sell you some.
Clinton you did a great job diagnosing and repairing the problem. Very educational video. Thanks. The little 5 year girl Ava Rigney that was diagnosed with cancer had her 1st. Chemo treatment and it destroyed 60% of it. She is back to eating,her bodily functions is working again, and she is wanting to pray. Thanks to all the Prayers but Thank God.
Clint, A little off-topic from today's video, but I recently moved to WNC and as I was driving on a local road, I had to do a double-take when I spotted a white HET parked in a truck shed. It's your HET wrecker! I noticed it has a different grille with the buyer's company name on it now. I was very surprised to find that, after watching the entire build, the truck ends up just a few miles from my home. I'm looking forward to seeing it on the road around here. I enjoy watching the content on your channel - All of it. Thanks!
I think he made the new grill for the company. Some reason i think i remember either seeing it ready to be loaded and shipped with the HET or he mentioned something about it.
Hope you get to see it working, that thing is a beast! Wish it was part of a towing truck otator TH-cam channel so I could see it doing recoveries. Like Jamie Davis, Pepe's towing, Ron Pratt, Murphys Diesel, Matt's off-road recovery or several others I can't think of right now.
Clinton, in the future you should remove the capacitor from the circuit before testing. It will give you a false reading if it is still connected to the circuit. Great job on the solder repair, looks like you’ve done this before…love your vids!
Thanks for another entertaining video Bub, that amazes me that those companies that repair that stuff can't do a good job. Charging like half price and then they do a crapy job putting it back together again. Glad you figured out how to bypass all that and refurbish it yourself.
Some questions and/or suggestions. Many companies, make an electronic cleaner to spray down the contacts on the connectors and the contacts of the controller. (CRC QD Electronic Cleaner)(available at Home Depot, Lowes, Walmart, and Amazon etc.) is just one example. After the contacts are cleaned off and blown dry you can put some dielectric grease on all the contacts to reduce corrosion and help keep them waterproof. The super glue you used seems to be just regular super glue which is very thin, like water. While that glue may keep the sticker on it will not do a great job on sealing moisture from leaking under the sticker. Loctite sells an Ultra Gel Control Super Glue that is no drip or run, impact and water resistant, and flexible. If you put a bead all around the sticker and around the view screen and push buttons it would do a much better job keeping moisture, dust, and debris out of the controller. (available at Home Depot, Walmart, Amazon, and Walmart)
Love the channel. I came to say the same thing about sealing up the display and buttons better to keep out the moisture. Also strongly agree that the new capacitors should really be supported for longevity. I've seen capacitors break loose over time in situations where the board is subjected to vibration and shock. All the best and really enjoying the content!
Clint has done a few of you guys a big favor here in showing this. How many of your equipment dealers would want you to see these tips I wonder! LOL. However, If any of you folks are planning to do work on electronics make sure, absolutely sure, that you buy solder, silicone and generally everything you may need and use, from an ELECTRONICS supplier. There IS a BIG difference in solder and silicones for electronics as compared to standard plumbing solders and silicones. ALSO, never, ever use your breath to blow dust away from electronics connectors, your breath contains moisture,... 'nuff said? I learned the hard way, and after some 40 years in the equipment business. I'm just trying to help you here. I am NOT being critical of Clint's work here, I am ( as I've said ) just trying to help some of you and steer you in the directions that may save you from getting a headache or two.
Clint, & have spent 70 years working in electronics, My only suggestion would be that you throw away that acid core solder. You need to be using rosin core solder. Nice Job. Gary In the beautiful Ozark Mountains of north West Arkansas
Agree from the flat farm land of Central Arkansas. I NEVER use acid core on anything. Solid with flux on plumbing, rosin core with Colophane flux on electronics.
I have been an electronics troubleshooter all of my working life and have saved my companies hundreds of thousands of dollars. Skills like these are always highly sought after and in demand! I am now retired and just today fixed an IC board on an FDM printer!
Greetings Clint I am an electronics guy who started my first job in a Radio-TV repair shop and then joined the USAF and later went to work for the military-industrial complex manufacturing sophisticated electronic equipment, satellite communications equipment mostly! Usually, when you're checking capacitors it should be done out of the circuit because the circuits around them may affect the reading! If you have good experience doing it your way and it works, so be it, but usually that's not the way it's done! Those are electrolytic capacitors that's why there is a positive and negative connection, which are usually used in the power supply to filter the power so you have clean DC voltage! AGAIN you guys' intuition and determination to get the job done as efficiently and economically as possible is a lesson to be learned by all in the trade! 👏🏽 👍🏼☺
Hi Mr C i have said it before on the comments but i will say it again my god you are impressive with the knowledge you have in your head thanks you for sharing
Clinton, maybe please talk to that local shop about offering to your national TV people to have them do the repair? That'll help support local business. 🥰
The Electrical Engineer in me was impressed. Nice work! One suggestion get an ESD mat and grounding strap. Those old electronics cannot take much of an ESD event. Testing capacitors can be effected by holding them or in circuit. Know what a new capacitor reads in circuit.
Great job Clint. I would recommend wearing a grounding strap, or standing on a grounding mat to eliminate any static electricity. One little jolt could fry the entire board.
Watching you work on this intricate parts reminds me of my 50+ year old son - how you both do it amazes me - control and determination to the max. Great work Mr C.
Back in the early 80’s I used to repair modems using the same capacitor replacement. Note that in circuit the tester will read capacitors differently than out of circuit. Good video!
What I always gonna kick your Out of this as a mechanic, There's so many different trades that you get involved in trying to make the machine work. You are a,welder, Diesel mechanic, Electronics mechanic, Paint, oil change technician, Hydraulic fluid technician, And a business owner!
I appreciate how you take customer issues so seriously and follow through with excellent application of years of knowledge. On top of all that, I also appreciate you sharing your repairs. Thank you so much!
Clint, I have been watching your channel for a few years. Today was one of the most interesting for me, being a guy with an electronics background. You really handled that job with a demonstrated expertise!
Good job on the Controller, Clinton. If you have trouble with electronic equipment the capacitors are a good place to start trouble shooting. There was a period of time when manufacturers focused on cheap & it was very common for capacitors to swell up & become dis-functional. When I was looking after a fleet of junk I found that dielectric grease was my friend for protecting electrical junctions from moisture & rust!
Hi Clint, another guy with 40+ years of board level maintenance under my belt. !-Never use Acid Core Solder, ALWAYS use some Rosin Core, that will avoid the acid destroying the board. Unsolder the caps for proper testing. Isopropyl Alcohol will remove flux after soldering is complete. I would have used some Silicone to put the switch board back, will hold really nice, plus add the waterproofing benefits that housing needs. Was there a new gasket applied when you replaced that module on the dozer? That Silicone would work there as well. Solder wick is OK, I prefer a good "SoldaPullit" unit to remove molten solder. Better is a vacuum heat unit, makes quick work in circuit board repair. I'm going to send you a care package of items, they will aid you in your next Board Level Adventure! Overall NICE JOB!
Awesome video Clint! I don’t know of anyone who figures out something like that and shares that information for free! You share so much information and knowledge it’s always appreciated and why we never miss a video from you guys! Way to go helping out the little guys like myself!Probably any electronic stuff that has capacitors would be worth trying that fix. I will definitely try that now if I run across a similar problem. We saw you guys out watching the helicopter near your shop today while we were heading home. Have a great day and thanks again!
You know your stuff Clint respect... The fix was easy but knowing what the problem was... Nice to see you went to a local "radio" shop, they know more about electronics or those things then the original engineers. They made their job out of their hobby. Top video!
For not being an electrician, I think you did a great job Clint! Thanks for sharing this video my friend, you made it look easy! All people have to do is watch Utube videos and learn, customer has to be satisfied when he comes back to pick up the dozer! It sure looks amazing Clint and Kevin’s awesome paint job! My oldest brother was a commercial AC engineer and he knows all about testing computer boards! Doesn’t do it anymore because he’s retired and has medical issues now! But if I need something I just call him! He’s always been one of those guys that takes things apart and studies them and usually fixes them! I’ve seen him tear down a starter when he was 19 years old and fix it! Thanks Clint! 🙏🏻🙏🏻🙏🏻👏🏻👏🏻👏🏻👏🏻👌🏻👍🏻👍🏻🇺🇸🇺🇸🇺🇸🇺🇸✌🏻✌🏻🙋🏼
As usual, Clinton comes through. Just a couple of points, not criticism just word of caution. When you get in that same position, remove the capacitor from the board, then test it. You can get a misread from the circuit, most likely from resistors can/does happen with other components. As you were told, within 10% of target ok, higher than, discard. You will read lots of different views on solder. Both acid and rosin (flux) cored can cause problems. Never use Lead free solder on old circuit boards, it can cause different problems. Finally, use thicker superglue, ask your local mom & pop store for the thicker type, it sticks to the plastic better and doesn't spread so much as the thin. Then use any bathroom sealant to seal up the bottom of case to prevent water ingress. Job Done. Hope that helps.Regards from UK.
I'd recommend being very picky about any sealant you use near electronics. Particularly "bathroom" types as they cure by the release of acetic acid (vinegar). That is really bad news for any electronics. The right sealants are readily available. I suspect that the bodges of sealant round those original capacitors are an indication that somebody has been in before you.
Having been a retired automotive field tech, I always appreciate the deep dive diagnostics, especially system "ghost" codes. High end audio/electronic shops might have these (capacitors). Little critters sure enjoy those warm electronics on a cold night. You're a great diagnostician and really enjoy this side too.
Great video. That’s a big reason why I watch the channel. It’s because you share your knowledge. Some folks keep the knowledge to themselves for the power trip. Keep teaching there are people watching who value your knowledge.
Micro soldering hobbyist here . I work under microscope. Damn fine job . There are UV cured / natural light cured sealants that allow for thermal conductivity you can use on repair areas to help guard agaist future corrosion. " UV Mask " with a UV light . Takes 30 seconds to cure . Love your videos
I was a TV repairman 35 years ago. The only way to get are accurate test on the capacitors is to test them out of the circuit. But they’re cheap enough, just replace them. Good job
My only suggestion would be to seal the plastic cover as well. Maybe some self adhesive foam tape or something. Silicon would be a bugger for the next person having a go at fixing things. Most electronics die from leaky caps. They leak electrolyte like dry cell batterys! Nice work Clint. Cheers and G'day from Tasmania
Nice job Clint. You're finally in my wheelhouse! That sponge on your soldering iron stand is to clean the tip. They work much better if you wet them and wring out the excess moisture, and THEN clean the oxide and burned flux off the tip. As others have said, replace the capacitors with an equal or higher temperature rating without exceeding the physical size (looks like height is the limiting factor here). Replacing with the same capacitor (assuming you can still get them) will ensure you have that third stability leg ... and should last as long as the originals did. The NTE replacement parts will work, but I am unsure whether they have the same working temperature range the originals did ... BUT at least you know how to replace them if needed. The silicon around the capacitors is indeed intended to reduce vibration ... and keeping the leads and circuit board from breaking. I'd clean the old stuff off and replace with a non-acidic RTV. Thanks for bringing us all along ... I'm certainly not about to go into the heavy equipment repair/restoration business, but as I've said many times "Work fascinates me ... I could watch it for hours". Regards, R
Great Job!!! I just repaired our dishwasher by replacing a cap on its board... Easy cheap fix that would've cost $200 for part + labor!!! Made my wife VERY happy ;-)
Clint, you are a guy after my own heart. If you don't know something you'll find out and learn. If you can do it yourself cheaper you will. Fix it don't trash it out of hand. That's the way I try and do things. Being a jack of all trades isn't a bad thing. You learn things and the knowledge can help a guy keep from getting screwed from time to time. On another note, do you care to share the name of the radio shop? I wouldn't mind visiting if I'm in the are and you never know what you can find. Good video as usual.
To the guy that was at the auction with the dump trucks. Loved ur comment on the mack truck. The mack b models and the steelnose dms with the steel dash are the true macks. Learned to drive on a b model mack concrete truck and did drive a dm 600 steelnose with steel dash. Like all the big 22 inch steering wheels and and love all the macks with with the steel spoke wheels. No bud or aluminum wheels. As a kid best time was n that concrete truck with dad.
It's really good that you are willing to dive into a board repair, Clint. I have done some of that work myself for different things that are obsolete or very expensive to replace. I have a good friend who is a retired electrical engineer for NIOSH who helps me out when I get stuck. He is amazing with anything computer or electrical related. Like myself, he is also a farmer, machinist, mechanic, welder, and will do aluminum casting work as needed. He also is a national repair center for an electric fencer company and usually has at least a dozen of those at any given time in his shop for repair. He can build boards from scratch, or reverse engineer them, and have the bare circuit board built, then fit the components himself. He has also done some board work on JD equipment that people bring him for repairs and countless other things. People who can repair things like we do are getting fewer every day, so I like to watch you work with your boys teaching them how to make those needed repairs and build things because they will keep that knowledge the rest of their lives that was passed onto them from you.
I think you should have glued the keypad and screen in with silicone or something else that is waterproof. I enjoy watching you flicks. Keep it up. Thanks.
Brilliant video Clint , big business just wants everyone to either buy new equipment or buy whole controllers or modules! Parts that used to be fixed with a cheap Oring , capacitor , brush set , seal kit etc are now required to be replaced with whole units . Yes large sections of society can’t put a plug on an appliance or even change a fuse🤯🤯🤯 but unless slightly more skilled people are enabled to repair we’re doomed! Thanks for the hard work involved in making your team’s videos, keep up the good work and keep making us laugh sausage fingers😂 crossed
Awesome video!!! Love this kind of stuff. The white strip down the side of a capacitor is always the negative. Little tip keep the videos coming Mr. C have a blessed week. Seen you were using harbor freight tools mine mine mine!! Lol 😆🤣😭
I spent my whole life working in an office, doing accounting work, so I had no clue what you were doing here, but it was interesting and very informative,so thank you for that. All the best to you, from the UK
Free advice from a veteran Aerospace Engineer that has dealt with electrical components for many decades (through the phases from Vacuum Tubes, thru hole and now surface mount components). Even with "power off", those same capacitors have enough power stored to set up "decay" in the PCB components; it won't "fry" them immediately but down the road, they will begin to fail. My un-named multi $Billion Company learned the hard way ... we even took away "Solder Suckers" from our techs as it was doing the same thing via the internal springs ... letting loose "ESD" pulses. The answer is easy ... "ESD Wrist Straps" ... no matter the situation. "Antistatic wrist straps are designed to prevent build-up of static electricity and safely ground operators who are working with ESD sensitive components, . Antistat's range of wrist straps are designed to be worn close to the skin establishing a path to ground." So please use one when handling PCB's and components ... you can't really believe how little power can affect SMT components like this. You're welcome. P.S. Poor design by JD on the cover ... would recommend using some foam tape ("weather striping") on the cover faces to prevent future ingress of water during life cycle.
Way back in 1971, I worked in an oilfield wireline shop. We had issues with capacitors in some of our older equipment. In the 1960's the capacitors that were common were paper and aluminum foil construction. In Louisiana, it is very humid and the capacitors were shorting out because the paper (dialectic) part of the capacitor would break down in the humidity. Our circuit boards were fixed by installing electrolytic capacitors. It sounds like the exact same problem you are seeing. In fact, the old devices you removed even look like the old style capacitors we were replacing. It is amazing anyone would still be using the paper aluminum foil type of capacitor.
Another brilliant video, Clint Knowledge is power. It's like these transmission controllers are a legacy product that is designed to fail. Low quality membrane switches die-cast aluminium enclosure, which suffers from corrosion and moisture. We don't have any radio shops left in the UK. We used to have realistic, radio shack, tandy & maplins for electronic components. It's a shame you can't get someone to read the eprom microcontrollers in the board and reverse engineer it then use one of the large high volume pcb companies like JLPCB etc and make new ABS enclosures I wouldn't recommend glueing in the membrane switches and screen with superglue as Cyanoacrylate doesn't handle vibration and cracks. I'd recommend 1.1mm 3M VHB 5952 double-sided tape Also, when replacing the capacitors, reapply hot glue around them to hold them as the machines inherent vibration can snap the leads (legs) soldered into the board. Big shout out from the UK audience 🇬🇧
Sadly Clint, I now remember you doing this before but completely forgot everything till you did it again. It is a great video and think if people just calm down, think things through, life will continue as our nation is under a bad administration and think oil instead of us, the people who placed them in office to help us maintain a normal to us now life. I am the chicken little and tend to throw my hands in the air till I just calm down and say hey,..... they still can't eat us.... can they??? LOL
This is the same repair made to lots of older electronics. Jeeps with a 4.0L have an ECU which famously fails, and the fix is to replace all the electrolytic (can style) capacitors. I fixed a couple of those, and also a battery tender, all by replacing the capacitors. Good stuff.
One minute, you're hitting things with a wreaking ball , and now you're doing fine soldering work. Very impressive.
That was my exact thought!
Capacitors should be tested out of circuit, hope this helps
Indeed. Must be removed first or you are not measuring anything of value.
Nice work Clint ;) Cheers Ray (UK)

Vets and dentist charge for their knowledge their time. Keep learning and save thousand.
Thanks for being kind enough to share your knowledge, coming from a UK guy thats never had a JD anything...
You know your stuff Clint respect... The fix was easy but knowing what the problem was... Nice to see you went to a local "radio" shop, they know more about electronics or those things then the original engineers. They made their job out of their hobby. Top video!
The placement of that unit fits into the 'designed to fail' category.
Damn Clint
You ain’t scared of anything are you????
My my !!! 😊
Bet when you started your garage, that one day you didn't think you'd be a computer engineer as well. 😎 👍
Clint taking care of his customers again. Nice work.
I do like the way you explain things.
Thanks for the video!
Good stuff Clint, who says experience isn't better than school. Keep on smiling.
Wow I learned something new again. That's what I like about your videos. GOOD WORK!!
It's like fixing an older tv
For not being an electrician, I think you did a great job Clint! Thanks for sharing this video my friend, you made it look easy! All people have to do is watch Utube videos and learn, customer has to be satisfied when he comes back to pick up the dozer! It sure looks amazing Clint and Kevin’s awesome paint job! My oldest brother was a commercial AC engineer and he knows all about testing computer boards! Doesn’t do it anymore because he’s retired and has medical issues now! But if I need something I just call him! He’s always been one of those guys that takes things apart and studies them and usually fixes them! I’ve seen him tear down a starter when he was 19 years old and fix it! Thanks Clint! 🙏🏻🙏🏻🙏🏻👏🏻👏🏻👏🏻👏🏻👌🏻👍🏻👍🏻🇺🇸🇺🇸🇺🇸🇺🇸✌🏻✌🏻🙋🏼
Gotta love that Super Clean after spray cough....
Excellent low cost repair Clint. $3.00 & a few hours sure beats $5,000.00 any day of the week.
As usual, Clinton comes through. Just a couple of points, not criticism just word of caution. When you get in that same position, remove the capacitor from the board, then test it. You can get a misread from the circuit, most likely from resistors can/does happen with other components. As you were told, within 10% of target ok, higher than, discard. You will read lots of different views on solder. Both acid and rosin (flux) cored can cause problems. Never use Lead free solder on old circuit boards, it can cause different problems. Finally, use thicker superglue, ask your local mom & pop store for the thicker type, it sticks to the plastic better and doesn't spread so much as the thin. Then use any bathroom sealant to seal up the bottom of case to prevent water ingress. Job Done. Hope that helps.Regards from UK.
I'd recommend being very picky about any sealant you use near electronics. Particularly "bathroom" types as they cure by the release of acetic acid (vinegar). That is really bad news for any electronics. The right sealants are readily available. I suspect that the bodges of sealant round those original capacitors are an indication that somebody has been in before you.
Isn't easy - when you know how!
You never fail to impress!
Thanks.
Ha Ha, that's the way the world go's round Clint. I'm glad you got to know how to fix these magical boxes.
Having been a retired automotive field tech, I always appreciate the deep dive diagnostics, especially system "ghost" codes. High end audio/electronic shops might have these (capacitors).
Little critters sure enjoy those warm electronics on a cold night.
You're a great diagnostician and really enjoy this side too.
No replacement for experience. Your depth of knowledge continues to astound me!
A privilege to watch you work!
i wish you would have tested the old ones after you took them out. Nice job
Same thought here. In circuit would read wonky. Need to test out of circuit.
Never need to amaze me. Your trouble shooting skills are great! Reason I like to watch.
Great video. That’s a big reason why I watch the channel. It’s because you share your knowledge. Some folks keep the knowledge to themselves for the power trip. Keep teaching there are people watching who value your knowledge.
Micro soldering hobbyist here . I work under microscope. Damn fine job .
There are UV cured / natural light cured sealants that allow for thermal conductivity you can use on repair areas to help guard agaist future corrosion.
" UV Mask " with a UV light . Takes 30 seconds to cure .
Love your videos
Clint, you are the man! It is very rewarding to watch too simple things to save thousands of dollars. I really like watching Mrs.C’s videos.
I was a TV repairman 35 years ago. The only way to get are accurate test on the capacitors is to test them out of the circuit. But they’re cheap enough, just replace them. Good job
My only suggestion would be to seal the plastic cover as well. Maybe some self adhesive foam tape or something. Silicon would be a bugger for the next person having a go at fixing things. Most electronics die from leaky caps. They leak electrolyte like dry cell batterys! Nice work Clint. Cheers and G'day from Tasmania
Clint, you're awesome ,macanics like you are a rare breed.
Nice job Clint. You're finally in my wheelhouse!
That sponge on your soldering iron stand is to clean the tip. They work much better if you wet them and wring out the excess moisture, and THEN clean the oxide and burned flux off the tip.
As others have said, replace the capacitors with an equal or higher temperature rating without exceeding the physical size (looks like height is the limiting factor here). Replacing with the same capacitor (assuming you can still get them) will ensure you have that third stability leg ... and should last as long as the originals did. The NTE replacement parts will work, but I am unsure whether they have the same working temperature range the originals did ... BUT at least you know how to replace them if needed.
The silicon around the capacitors is indeed intended to reduce vibration ... and keeping the leads and circuit board from breaking. I'd clean the old stuff off and replace with a non-acidic RTV.
Thanks for bringing us all along ... I'm certainly not about to go into the heavy equipment repair/restoration business, but as I've said many times "Work fascinates me ... I could watch it for hours".
Regards,
R
Great Job!!! I just repaired our dishwasher by replacing a cap on its board... Easy cheap fix that would've cost $200 for part + labor!!! Made my wife VERY happy ;-)
Great video Clinton it’s amazing how a cheap part can cause so much grief and how much company’s like to charge to fix a small problem 👌👍
Clint, you are a guy after my own heart. If you don't know something you'll find out and learn. If you can do it yourself cheaper you will. Fix it don't trash it out of hand. That's the way I try and do things. Being a jack of all trades isn't a bad thing. You learn things and the knowledge can help a guy keep from getting screwed from time to time. On another note, do you care to share the name of the radio shop? I wouldn't mind visiting if I'm in the are and you never know what you can find. Good video as usual.
To the guy that was at the auction with the dump trucks. Loved ur comment on the mack truck. The mack b models and the steelnose dms with the steel dash are the true macks. Learned to drive on a b model mack concrete truck and did drive a dm 600 steelnose with steel dash. Like all the big 22 inch steering wheels and and love all the macks with with the steel spoke wheels. No bud or aluminum wheels. As a kid best time was n that concrete truck with dad.
This is oddly fascinating, glad to see it work!
Your depth of knowledge is impressive, to say the least, Clint.
You’re a man of many talents Clinton. Why not have a go,what’s the worst thing that can happen? Well done!..🇦🇺🍺🍺
Great idea about supporting the local shop. 😊😊😊
liked the comment " I'm going back to the mom & pop store to keep them in business - good on you
Thank you very much Clint for sharing this kind of knowledge, many would keep it to themselves by charging a lot for their repair! THANKS !
Very nice to support your local shop. Also nice to have a local shop !
It's really good that you are willing to dive into a board repair, Clint. I have done some of that work myself for different things that are obsolete or very expensive to replace. I have a good friend who is a retired electrical engineer for NIOSH who helps me out when I get stuck. He is amazing with anything computer or electrical related. Like myself, he is also a farmer, machinist, mechanic, welder, and will do aluminum casting work as needed. He also is a national repair center for an electric fencer company and usually has at least a dozen of those at any given time in his shop for repair. He can build boards from scratch, or reverse engineer them, and have the bare circuit board built, then fit the components himself. He has also done some board work on JD equipment that people bring him for repairs and countless other things. People who can repair things like we do are getting fewer every day, so I like to watch you work with your boys teaching them how to make those needed repairs and build things because they will keep that knowledge the rest of their lives that was passed onto them from you.
Awesome to see you dropping actual knowledge for people to do it themselves online! Great channel
I think you should have glued the keypad and screen in with silicone or something else that is waterproof. I enjoy watching you flicks. Keep it up. Thanks.
The dozer whisper. Nice
Brilliant video Clint , big business just wants everyone to either buy new equipment or buy whole controllers or modules! Parts that used to be fixed with a cheap Oring , capacitor , brush set , seal kit etc are now required to be replaced with whole units . Yes large sections of society can’t put a plug on an appliance or even change a fuse🤯🤯🤯 but unless slightly more skilled people are enabled to repair we’re doomed!
Thanks for the hard work involved in making your team’s videos, keep up the good work and keep making us laugh sausage fingers😂 crossed
Awesome video!!! Love this kind of stuff. The white strip down the side of a capacitor is always the negative. Little tip keep the videos coming Mr. C have a blessed week. Seen you were using harbor freight tools mine mine mine!! Lol 😆🤣😭
Very helpful, thanks for taking the time for this multi dollar saving video. Keep up the great work on your channel.
I always learn from your channel my friend! I’m retired but I can still learn things! lol 😂 😂
Hey man that DeoxIT D5 spray electronic cleaner does miracles on electrical connections.
I spent my whole life working in an office, doing accounting work, so I had no clue what you were doing here, but it was interesting and very informative,so thank you for that. All the best to you, from the UK
Great video Clinton, as always. I hope folks understand the tips and tricks you pass on have cost you countless thousands of dollars to learn.
Free advice from a veteran Aerospace Engineer that has dealt with electrical components for many decades (through the phases from Vacuum Tubes, thru hole and now surface mount components). Even with "power off", those same capacitors have enough power stored to set up "decay" in the PCB components; it won't "fry" them immediately but down the road, they will begin to fail. My un-named multi $Billion Company learned the hard way ... we even took away "Solder Suckers" from our techs as it was doing the same thing via the internal springs ... letting loose "ESD" pulses. The answer is easy ... "ESD Wrist Straps" ... no matter the situation.
"Antistatic wrist straps are designed to prevent build-up of static electricity and safely ground operators who are working with ESD sensitive components, . Antistat's range of wrist straps are designed to be worn close to the skin establishing a path to ground."
So please use one when handling PCB's and components ... you can't really believe how little power can affect SMT components like this. You're welcome.
P.S. Poor design by JD on the cover ... would recommend using some foam tape ("weather striping") on the cover faces to prevent future ingress of water during life cycle.
Thanks for the advice -Kevin
Way back in 1971, I worked in an oilfield wireline shop. We had issues with capacitors in some of our older equipment. In the 1960's the capacitors that were common were paper and aluminum foil construction. In Louisiana, it is very humid and the capacitors were shorting out because the paper (dialectic) part of the capacitor would break down in the humidity. Our circuit boards were fixed by installing electrolytic capacitors. It sounds like the exact same problem you are seeing. In fact, the old devices you removed even look like the old style capacitors we were replacing. It is amazing anyone would still be using the paper aluminum foil type of capacitor.
Probably because they are cheaper in the short haul.
Low bid. Everything by Deere is low bid.
trying to watch your live at the same time.All kinds of great content ,thanks Clint
Another brilliant video, Clint
Knowledge is power. It's like these transmission controllers are a legacy product that is designed to fail. Low quality membrane switches die-cast aluminium enclosure, which suffers from corrosion and moisture.
We don't have any radio shops left in the UK. We used to have realistic, radio shack, tandy & maplins for electronic components.
It's a shame you can't get someone to read the eprom microcontrollers in the board and reverse engineer it then use one of the large high volume pcb companies like JLPCB etc and make new ABS enclosures
I wouldn't recommend glueing in the membrane switches and screen with superglue as Cyanoacrylate doesn't handle vibration and cracks. I'd recommend 1.1mm 3M VHB 5952 double-sided tape
Also, when replacing the capacitors, reapply hot glue around them to hold them as the machines inherent vibration can snap the leads (legs) soldered into the board.
Big shout out from the UK audience 🇬🇧
Sadly Clint, I now remember you doing this before but completely forgot everything till you did it again. It is a great video and think if people just calm down, think things through, life will continue as our nation is under a bad administration and think oil instead of us, the people who placed them in office to help us maintain a normal to us now life. I am the chicken little and tend to throw my hands in the air till I just calm down and say hey,..... they still can't eat us.... can they??? LOL
This is the same repair made to lots of older electronics. Jeeps with a 4.0L have an ECU which famously fails, and the fix is to replace all the electrolytic (can style) capacitors. I fixed a couple of those, and also a battery tender, all by replacing the capacitors. Good stuff.
Slick job mate, and it’s good that you’re passing on this knowledge. 👍
Quality work as always.
Just imagine 6 miles in the bush working. Just because of two little....
-40 walking out. Rather have a older one rebuilt.
Your skills at repairing EVERYTHING are truly amazing. Well done!
Great video clint!!!...lots of guys could benefit from this!
Dude your knowledge of all these different machines is really something!!
