I just wanted to make sure whereas the GMC is Pos. ground and the Chev. is Neg. ground. My thinking is that it should make zero difference to the generator, the rotation is the same on both engines, output should be the same...etc...etc...
I need a serviceable generator to replace my bad existing generator. | | | | | Joined: Feb 2004 Posts: 29,850 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,850 | A generator can be polarized either way. The part numbers might not match up between Chevy and GMC, but as long as it's polarized properly the charging system should work OK. Not so for regulators- - - -most of them are polarity-specific.
