If you like having your cars in top condition and enjoy working mechanically you quickly find out that having tools and hobby is better than paying for gamble called mechanicall roulette. + no mechanic gives single sheet for tiny details... You can do it far more a better than some worker under time pressure. And no one gonna make things like replacing hardware with stainless where it makes sense

[@CanadianPenguin_]

If you work on your own car your gonna have most of those tools. Soldering iron and multi meter you can get fairly cheap, you can get away with no press if you use a hammer carefully, a lot of parts shops offer rental for bearing pullers or ever let you borrow it for free for a day.

[@tommost1]

If you don't have a vise in your shop then go out and get one right away. They're indispensable.

[@johnjensen2217]

Cool video but I would offer one recommendation. When cleaning the stator core iron laminations always run your cleaning tool parallel to the laminations. If you run the tool across the laminations and accidentally smear some metal across the laminations you will short the laminations together potentially creating a hot spot in the core.

This is so cool for you to make and share. The work shows that it's possible to repair, but also shows why it's a rational thing to purchase new. Not many part shops would show you in detail how to save cash, instead of just explaining why it's difficult, you show how and why. Thanks!

Thanks for the clarification, we'll think about what we can do with this in new videos.

[@ReallionaireDad]

I came here to study rebuilding an alternator for my Dodge Ram 1500 work truck. While I can afford a new one, I just knew there was a more affordable way cost wise; not sure if it’s more efficient time-wise. Nonetheless, I think I will buy the new alternator, and learn to rebuild the old one using this video and others. I’m even considering pulling the new one after the rebuild, and just use the new one as a backup. This was a satisfying watch start to finish. I think the only skill I like at this point is soldering which I can acquire with some training as well. Lastly, I’d need to acquire a few of the tools he used that I don’t have, but most everything else is covered.

Looks really smart... there is a positive terminal, how does the alternator ground to the battery? Generally through the engine block via the alternator mount then the earth strap. Here it has to go through a layer of nice orange paint. ie) mask the mounting faces before painting if you want the alternator to work.

Alternator Story Time: Had a 1986 Pontiac Firebird once. One evening going down the highway, the faster I went, the brighter the lights became. I limped the car home, going slow, as to not burn everything up. I took the alternator out, replaced the voltage regulator and the same thing happened? NAPA said the "new" voltage regulator I just bought from them was bad 🤔 so I purchased another voltage regulator. The alternator worked just fine after that. Definitely time consuming doing the repair twice!

The thing is that most of the parts like this you find online are refurbished original parts. Usually if it requires the old part in exchange for the new part, it's definetly a refurbished one.

[@KekeeBlack]

Yes 100%. It is worth an attempt at repair for original parts because you know it worked at one point. The new parts you have no idea if they work or if they are going to go bad in 500 miles because manufacturing tolerances have gone out of whack these past few years. I also don’t want to wait months on a new OEM part. The 1 or 2 days this takes to do, to me at least, is worth it to avoid waiting 4 months on a $300 part.

[@kristoffay1476]

This particular brand of altenator (Mitsubishi) is a very common system used by many manufacturers like Suzuki, Honda, Mitsubishi, Mazda, etc. with different regulators, communication protocols and mounting ears , and it can have four main weakness: regulator, stator, rotor, and contact points. Regulators: all D-P pin marked regulators (com. protocol introduced by Mazda in the very early times) with the three pin layout connector are sensitive, and commonly die if the brushes making arcs, because of the wear and grooves of the sliprings. It's the same with the honda three pin connector C communication protocol regulators. The toyota type two by two pin connector regulators with P-D or C data communication and all other regulators with lamp outlet are very reliable and mostly survive the harsh conditions like induction and high voltage peaks from the slipring sparks. Stator: They use a special thin surface impregnation (black epoxy) on the stator dynamo plates, instead of insulating sheets. 1 of three of this altenators need a stator rewinding, because, as the plates corrode, they expand and getting closer to the winding loops at the edges and making a ground short circuit. Faulty, expanded, corroded stators are valuable, because there are no other good alternative for them to replace. Chineese, aftermarket stators has very bad quality, low quality copper and non ferromagnetic steel plates which gets them overheated and burnt all the time. The factory stators can be burnt out, cooled down on a supporting cylinder, corrected on the lathe and rewinded by specialist using insulating sheets inserted into the grooves. Rotor: the slipring-brush pairment is overall optimal on this altenator system, so sliprings often need just to be turned and polished on the lathe to remove the grooves. But, as the sliprings are bigger diameter then usual, they have a higher tangetial velocity so even small grooves on the sliprings can lead into brush sparking and popping, and that small thing makes the altenator bad. Always check brush twisted connecting wire for fatigue. In 1 out of 10 altenators the rotor coil outlet wires around the slipring soldering or inside the insulator tube corrode (green corrosion product is visible) and the rotor coil gets a wire break, which is often invisible, because it can happen inside the coil too. First case can be easely repaired if there is enough wire lenght left to make an extension. Always use FBS glue fillout to take off the centrifugal loads from the the soldered connection. Contact points: Inside the altenator the negative power diode bridge and the ground point of the regulator are making the ground contact directly through the internal aluminia surface of the back case. This promotes the contact corrosion of the backcase and it leads into regulator malfuncion and high internal voltage drop (low voltage charge output on the vehicles grid), so in mani cases the altenator needs to be cleaned at this contact surfaces to resurrect. Older Mazdas have the windscreen washer fluid filling hole near the altenator connector, so small leaks slowly corrode the altenator connector wires. My opinion on the video: rust removal and painting the stator is necessary to prevent the corrosion and expansion, but painting the inside oft the back cover is a mistake, and the ground contact surfaces will never make contact again.

@@uranusneptun5239 indeed it is made out of aluminium alloy and often the engine block too which it is attached to. The engine is grounded with a wire and that is the only ground the alternator uses.

The coils have lacquer on them to prevent them from shorting out. Is there any concern with using cleaners on the coils that might degrade the lacquer and lead to an electrical short later on?

The cleaning agents used are not aggressive and do not affect the varnish.

[@deedle6073]

Wouldn't painting it interfere with the heat dissipation?

[@alejandroperez5368]

Interesting question. This is mentioned when painting brake calipers too.

[@us7876]

Neither alternator housing or caliper have heat dissipation as a primary function. Since they are not static parts (internal rotation moves air plus the car is moving) there should't be a problem. Also painting a literal heatsing with several coats (~0,2mm) only worsen temps by 2-5°C increase

You can pry and tap the rear housing and stator assembly first before you remove the pulley, this way you can hold the rotor and rattle off the pulley and you wont need a puller to remove the rotor from the rear housing. I would have replaced that slip ring instead of machining it unless you had a spare rotor, also get a bigger soldering iron.

is this really worth it if i can buy a new one, i mean the parts to do this must be more expensive than a new one or just as much

[@MattyH64]

Not all alternators can be bought new.

[@stco2426]

Lovely. I like the trick to hold the brushes back. Very good and a great video. What were the cleaning solutions, please?

[@autodocuk]

Thank you for your feedback! In the description of the video, you will find all the links to all the products in the video.

[@RobertYayo]

So only the regulator guts get changed, once gutted, is that what you took off/ installed with the soldering gun?

[@warmaster1001]

Great video idea! Especially since the alternator I ordered from Autodoc was defective right out of the box!

[@autodocuk]

WOW - a 10 of 10 !!!! Great Work!

[@danceHHmusic]

What is that drip/ tray they you were cleaning parts over?

[@Tonyv1951]

Brilliant. So much better than throwing it in the trash.

[@HakimiYT403]

Bruhh.. Is it painting the alternator body not making the grounding worst?, THX

[@Xiltch]

Love watching this but given the amount of time, it's cheaper to pay a mechanic to replace it. This guy just made that look super easy when most people struggle just to change a tyre.

[@spotmyimpactbro]

Satisfying to watch. Silence is under rated.

Hi Thank You. What type of solderind was used?

[@HOVREDDY]

My grandfather used to work at a gas station/auto repair shop back in the 70’s. He said when someone drove in with a bad alternator, they’d tell the customer “No problem! I’ll get you a new one. Be back in 30 minutes.” They’d take the bad one out back into the shop, disassemble it, clean it up like this video, and paint it with silver rally wheel paint to make it look brand new. 15 minutes to take it apart, clean it, and spray it after making sure it works. 15 minutes for the paint to dry. They’d come out to the customer with the old alternator and sell it as a brand new one. That’s one of the ways the shop made extra money.

This guy is good new techniques to all car enthusiasts

[@BBQTheRaptor]

For those learning and wanting to do this themselves, how long in total did it take you to do this? Granted you went above and beyond what most do, just trying to get an idea.

[@audiwankenobi361]

Aye! This was very interesting! I've been using your videos for my VWs for quite a few repairs now. Respect from Daytona Beach Florida!

[@autodocuk]

We are glad that this video was useful to you!

[@Arexodius]

Love it! Came out super clean. One question: Did you not use any anti-seize or dielectric grease when re-assembling? If you go through all of that trouble restoring it, would you not want to prevent future seizes and hiccups? Swapped the alternator on my 1989 Toyota Celica couple of years after I got it. Looked half decent but didn't work. Got a new one for 200 euros. If that one ever fails I might try this instead.

Great video AutoDoc! Thank you

[@WiPri0371]

This was one of those "satisfying to watch" videos. I was also wondering how the brushes were going to be kept out of the way.

[@SaycoPworrell]

awesome, wish he did a complete rebuild doing a full rewind of the coils.

[@StefanCiob]

NICE

[@CalligraphywithAnas]
