alternator upgrade choices
Posted by: Ron62 ()
Date: October 11, 2019 12:52PM

Im planning un upgrading from the stock 37 to a 63 amp 10si alternator. Can anyone who has done this recommend any brand of either rebuilt or new that has held up? Most of the reviews I see on Flaps sites aren't very good.

Thanks
Ron

I bought an Internally Regulated High amp alternator from California Corvairs!

It works great!

JMHO!

Looked at those but the price is a bit on the high side for me.

I have never had any real issues with better rebuilts from major local parts stores.

If you buy the FLAPS better version you get a longer warranty. I've had to return a few FLAPS rebuilt alternators, but so far none of them were rebuilt 10SI units. Keep in mind a "rebuilt" is only cleaned up and the bad parts replaced.

The best rebuilts are usually done at a small independent shop, but you pay more and the little independent rebuilders are mostly gone now as they can't compete with the FLAPS. The few that remain tend to specialize in old generators and starters that the FLAPS don't carry.

and remember, if you buy a new SI and take the front end off to replace with the Corvair specific front mount, you effectively void any warranty (if they can figure that you opened it up)

Id have to take my chances with the warranty I guess. My car has the original alternator and regulator. I would rather to go an internally regulated version and up the amperage as im adding power hungry accessories.

If you have time, energy, and some skills (and a local self serve junkyard) go to the yard and purchase a good looking/clean IR alternator assembly. They are pretty easy to assemble using the Corvair specific pulley and front half. Ron, is your car a 62 with a generator still?

Hi Tim,
No My car is a 67 Coupe. Sorry should have mentioned that. Wasn't thinking of going the junk yard route only because of the age of a 10si. I dont think they have made them in production for quite some time. I could be wrong of course.

I you go to the junkyard, keep in mind the 10SI came in different amperage ratings. Usually cars with A/C have the 65Amps units.

My '91 C3500 doesn't have a 10SI. My '84 Caprice does.

Look for a interchange 7294. Say a 85 Buick Riviera.

Just get the "used parts emporium" one and put new brushes and bearings in it while you are transferring the pulley/fan/housing. It will last for YEARS!smileys with beer

Unless the unit caught on fire, only the brushes and bearings wear out. Yes, the regulator fails, but at the same rate a new one fails!winking smiley

If you really need the extra Amperage and know how to swap the fan and front case half, you might consider this.

Use a higher amperage 10DN and you don't have to mess with the wiring.

Swap the Corvair specific Alternator parts and reinstall as original. No need to hack up the original wiring.

I've just been buying rebuilt Wilson 90-01-3106 63 amp internal regulator from O'Reilly's for $50 and switching the Corvair base. I don't suppose Mister Wilson is happy with my old Corvair core, I'm a menace.

I had one this year that wasn't charging. I put it back to it's original configuration when returning to the store. They tested it and it wasn't charging so they gave me another one and all was well. I don't think I did anything wrong when changing the base...

Many of the rebuilt real Cover type alternators are now 48 amp version used on AC cars.

A bad Ass Battery and a 100 amp Alt is the way to go. At Idle in the winter with the heater, Lights and wipers on the lights will stay bright, wipers wont slow down. If you Have AC Yes A big Alt. Mike

Keep in mind the GM 100Amp alternators had a revised fan and housing to improve cooling that CAN NOT be used with the reverse rotation Corvair. The 10DN 10SI units had a cooling systems are rated for a MAXIMUM 85Amps. On a hot day 65 Amps is about the limit.

Nothing wrong with an aftermarket 100Amp 10SI as long as you don't run it at more than 65Amp continuously with the Corvair alternator fan. Also check the output vs. speed amperage chart - some "high output" modified alternators put out less amperage at low RPM than the old stock units.

Agreed - that's why I keep the original housing and fan in the original rebuilt box in case I have to return it during warranty.
