I’m having some charging issues this year and previously I have not had any issues charging so the issue is not relayed to the way it’s wired but I just replaced the overdrive. My car has a negative ground so the information for testing the generator seems like it may not be exactly right.
For exam it says to ground the field terminal to bypass the regulator and go full charging. But I’m assuming that’s with a positive ground. So do I connective positive to the field terminal?
Mainly what I’m finding is that my charge meter will be indicating normal which was middle to just over middle as revs increase. Then it’ll start dropping to full draw then just below middle in the draw area and my overdrive quits working because the relay won’t close.
I have a rebuilt voltage regulator and generator but I want to actually
Test and diagnose the issue instead of throwing parts at it. Just how
I am.
