It may be that it only has 3 caps since when I have tested the voltage after a full charge on a battery charger it only registers 6.5 volts but then if I am charging it with a 6 volt charger that would also make sense that it only charges to 6.5 volts. Since I have no way of visually checking the battery at the moment this will remain a mystery.

You stated in one of your other replies to my posts "I might look toward intermittent conditions for the kind of radical jumping ammeter readings that you report. Maybe wiring shorting or bad/loose/intermittent gen and/or VR grounds."

This reminded me that after I put the first new VR on I did drive the tractor down a path in the woods, it was bumpy, when I would hit a bump the ammeter would in most cases jump to a different level, maybe from -30 to -20, then hit another bump it would jump back up. I even raced the engine while not moving ant the ammeter would go back to +1 for a time until it got jostled some more. Could this be that the field on the generator may be grounding against the generator housing and jostling it causes it to ground at vearious levels? Boy I wish I had access to the trator I would like to try some of these things.

Quoting Removed, click Modern View to seeWe can guess forever, but with too many unknowns to do any good. Need to know if battery, gen & reg are 6/8/12v?

I agree until I can get back to the tractor, and get all the right information, plus do some other things there is no way to diagonose the problem. Thanks to all for the back and forth discussion. I will let you know how things are going when I have done some of these things.
