CHEAP GM one-wire alternator upgrade for the FLOODED Corvair! Double your charging power!

[@HAVOCRISING_]

Man you have been a good teacher for me, after watching your videos I have been climbing all through out my 65 and learning and checking everything! Thanks from Texas - Havoc

[@AutoAnatomy]

Thank you for the kind words, hope it’s helped!

[@arizonaguy7574]

Great job bringing the Corvair back to life and awesome job in documenting the journey.

[@AutoAnatomy]

Thank you!!

[@vayabroder729]

Awesome work; I wonder why you didn’t clean up the front part and make it look nice. Makes sense to get in cleaning, reconditioning and painting stuff up as you go and save yourself time doing it later?

[@AutoAnatomy]

I wanted to verify proof of concept, will probably go back and clean up now that I know it works.

[@howardkoster4026]

Great point about supporting the lower control arm before removing shocks. 1st time I removed front shocks on my Valiant, I didn't realize this..

[@AutoAnatomy]

It only takes once to learn that lesson!

[@arrowblockentertainment7893]

Great video. I remember using a very similar alternator to convert my 1961 Oldsmobile from a generator to alternator. The generator never worked right even when rebuilt. Alternator is the way to go on cars.

[@AutoAnatomy]

Thanks!

[@DavidMartin-mz8jj]

Being a motor mechanic many years ago I can see that you are a very competent guy. I loved your work and approach.

[@ricknorris6943corvair]

I did this before but on my 66 turbo I got a chrome unit from Amazon. I then repainted the Corvair side after blast cleaning it. Chrome is fast!

[@MrGlideral]

Well done, my first car was a Blue 1966 Corvair 110 Monza with a 4 speed. Your project gave me flashbacks to all the same things I did in my senior year in auto shop, man they are a fun ride. Thanks

[@AutoAnatomy]

Thank you!

[@67Stang]

I know this is an old video but just found the channel. I did similar replacements on my Mustang. I had to clean and paint the old parts before I put them back on though. New bushings made a big difference.

[@AutoAnatomy]

Thanks for checking out the channel, and the 67 Mustang is one of my favorites!

[@servicetechnician3264]

Hello Sean. I am glad you found this car to work on. It looks like a fun project. I noticed that you are very knowledgeable about the cars you have been refinishing/restoring. Keep up the good work. I am enjoying your videos. George B. in Michigan

[@AutoAnatomy]

Thanks George! Glad you like the videos, and hope to keep bringing classics back to life for a long time

[@SpeedyG289]

Nice work, bushing are often overlooked, they can definitely make a car go from deathtrap to a really nice driving car.

[@parribaby8049]

Where did the white wire to the alternator go ? Could you share any feedback

[@AutoAnatomy]

Going by memory, but I don’t think it’s connected at all.

[@danr1920]

On mine, I replaced all the bushings, springs, shocks ball joints and tie rods front and rear. Was like a new car. I never upgraded the alternator. I suppose if it needed replacing I'd think about it. 37 amps is plenty for me and my car. Perhaps you are putting more stress on the belt.

[@kenedmisten7995]

I bought an 65 amp Alternator at the corvair swap in Palm Springs. I think it is one wire set up but has the original connections. I was wondering about wiring. A

[@Friedbrain11]

I did basically the same thing except I used the newer pulley and fan. Worked just fine and the 10si/12si only outputs 63 amps stock. I used to rebuild the things as well as starters and electrical systems on automobiles.Good kob though.

[@AutoAnatomy]

I believe the alternator fan on the Corvair is reverse rotation, so you may want to check that.

[@tomhughes6486]

@@AutoAnatomy You are correct. For a Corvair, you MUST you the original, stock fan pulley for the alternator.

[@kenwatman5959]

Cleaning assemblies before reinstalling should come a little closer to the top of the list . T he wire wheel on a bench grinder is mighty helpful In quickly preping parts for a spray bomb of quick dry chassis paint !

[@solo2r]

Not really a '1 wire' Alternator! On a Corvair, it is VERY important that the 'Gen/Fan' light on dash works! This light on when driving tells you that the alternator is not turning hence the cooling fan belt has come off/ broke.

[@AutoAnatomy]

What's interesting is that my Gen/Fan light works (somehow), even though I didn't hook it up. I was told that on some cars it needs to be hooked up and some it will work without. I tried without and it worked, guess I got lucky. Sean

[@tomhughes6486]

​@@AutoAnatomy When you say "it worked", did you test it with the fanbelt off, and did the light actually stay on? Or did you disconnect the wires going into the alternator, and did that cause the light to come on?

[@Rick-O-Shay60]

@@AutoAnatomy Here again proves you don't have a One Wire alternator. Try unplugging the two prong field plug on the alt. and you will note the alt light on dash will illuminate. Luck has nothing to do with it. With a One Wire alt will not operate the warning light on dash because it loses the signal from the alt. that turns off the light. The warning light will stay on with a One Wire even if it is charging. One Wire alternators are not ideal for street because of this. They were actually designed to work on commercial vehicles such as tractors, etc.

[@MrWaalkman]

Kinda looks like your old alternator was an upgraded one based on the color difference between the front half and the rear half. And the windings look pretty much the same between the two, not sure how the new one would provide more power. Nonetheless, this will be my go to video for if and when I need to do mine. Thanks!

[@mikeconnelly7032]

Did you have to bend the alternator brace so that it mounted to the new backside of the alternator? I did not see any spacers.

[@AutoAnatomy]

No, it just bolted right up without any modifications

[@mikeconnelly7032]

@@AutoAnatomy I used a 76 Camaro alternator. I clocked it correctly. But needed spacers at both ends

[@matthewcalifana488]

Thanks for a great video , Maybe someday i,ll get a corvair that,s not 90% rusted out / Yours looks pretty good , Best Wishes !

[@kyledavis4890]

Ours has a generator, is the mount different for a generator vs. the alternator? Also, do you have a part number for this gm one wire alternator?

[@AutoAnatomy]

No idea about the generator, but I would assume it would work the same way. I picked up one for a 1978 Camaro from RockAuto. Here is what I got: www.rockauto.com/en/moreinfo.php?pk=3379887&cc=1035188&pt=2412&jsn=1

[@davidp187]

Hi Sean, I like your real life videos! Can you tell me the part number on that alternator?

[@davidp187]

It doesn't mater, one needs the wire to the dummy light.

[@Monza62000]

remember the eng runs backward ,,air has to flow from the back to the front,,,..i got a new one from rock auto had the wrong fan on it...

[@AutoAnatomy]

I swapped the fan from the old alternator to the new one. You’ll see exactly what I did in the video

[@tomsheets6399]

Enjoyed the video. thank you

[@AutoAnatomy]

Thanks!

[@rupe53]

Double the charge rate is a great idea but the OEM wire is only #10 so kinda light for the extra amps. You might want to run a second wire over to the battery. Also, on the wiring harness on left side near the carb has a molded plug and if there's a poor connection in there (probably!) it will melt the plastic by the heavy wire feeding to the front. Ask me how I know this and I will tell you I had to source another harness section from a donor car because the melted plug would not fully seat and just made more heat. Adding more amps might make that condition worse. That wire feeds the wipers, heater blower, and the headlights. IOW, 95% of the car's needs. Clean it up or it will bite you later.

[@AutoAnatomy]

Good to know, thanks for the info!

[@shelliecarlson7015]

The only thing I would've done, clean the front housing, and run a heavier gauge wire off the output. You double the amperage, should double the road between.

[@AutoAnatomy]

That's on the to-do list for sure!

[@twistedwired]

I need me one of them power ratchets

[@AutoAnatomy]

Makes such a big difference!

[@gvet47]

You are driving me crazy! Why when you have things apart do you not clean them up. Front of the alternator and fan is a mess and the struts and suspension parts are still a rusty mess. 🤔

[@AutoAnatomy]

Proven fact…the camera adds 15# more rust.

[@tomhughes6486]

Time is precious. Cleaning something just to make it look pretty without affecting its ability to do its job can be a waste of time on a vehicle that is not a show car.

[@Monza62000]

that has the org shocks ..keep them...some are rebuilding them ,,,i worked on the line that made them....ok showing my age lol....

[@AutoAnatomy]

I kept them, now to find someone who wants them!

[@Rick-O-Shay60]

That's NOT a one wire. That is a internally regulated 10si. A true one wire does not use the two prong field plug connected to it.

[@AutoAnatomy]

True, but I think many refer to this style alternator as a one-wire.

[@Rick-O-Shay60]

@@AutoAnatomy Only those whom are mis-informed. So let's be clear, What you have here is a three wire alternator.
