Re: Charging system issue

Grounding the Field terminal did not affect the voltage at all, so I will pull the generator and replace the brushes to see if that does it.
I spend about 1/2 my time in China, so I don't have many weekends to work on the car. But, plenty of time to order parts. It will probably be mid-March before I have a go at this.
One thing I noticed as I was trying to figure this out. My regulator terminals are F, Gen, Batt going from driver to passenger side. The ones I see on line that purport to fit my car seem to go from Batt, F, Gen. Not sure why this is or which is correct?
I frankly do not remember if this system ever worked, I got the car just as I began my gig in China and it literally sat is storage for a year before I could touch it. Then six months doing brakes, wheel bearings, ...
It came with an 8 volt battery, grounded negative (which I assumed was incorrect). I put in a dry cell as they have been pretty bullet proof in my cars. I did hook it up positive ground, but my understanding is that there is not much in the charging system that really cares.
Now I wonder if it has actually been changed to Neg ground (what would that entail) and is there a way to tell. The radio does not, and never, worked even with the 8V in the car. Everything else (except of course the charging system) seems to work fine.
Can this be causing my current problem?
