Re: Adjusting the Voltage Regulator

There is a gent who is on this forum who does generator rebuilds. I got parts from him and did my own.

It all started when the aftermarket regulator in my 54 Cavalier failed.

I first bought an old stock unit on EBAY which works fine then I ended up buying an original new old stock regulator (Delco-Remy) from the gent.

Both regulators I had to burnish the voltage relay contacts before it would work, like some kind of oxidation.

I did learn the contact material is different in a Pos ground vs a Neg ground unit.

My generator is rated at 45 Amps and the old after market seemed to have to light duty contacts in the cutout relay which actually welded shut and left the generator connected to the battery, which may have led to the failure of the commutator in the generator.

The whole story is in a thread on here about november of 2012.
