It doesn"t change at all with the rpm"s? Where did you get the VR from?

Jason, no change with RPM's. Got it off Ebay. No markings at all on regulator, just the lettering on the terminals.

Was the regulator marked for 6V positive ground? They usually are. What happens when you pull the negative cable off while it's running? If it keeps running, drive it. Although I can tell you from personal experience I had the amp gauge go bad on our TO-30 many years ago and it wouldn't charge until I jumpered around it.

Is the battery discharging? Keeping a charge the whole time it is running? Then there may not be anything wrong. You wouldn't want 8 or 9 volts constantly going into a 6 if the battery is fully charged. If the VR invisibly keeps up with the discharge of coil and points, but you don't notice the needle bobbing now and then- the only time you will notice the needle go up is after you start it again, and the battery has a drain to recover from. That could take several seconds to a few minutes... but then the needle can sit at zero almost the rest of the day, wait till the tractor can't start anymore before you fix anything. The voltage 'regulator' might just be 'regulatin'...

Thanks Tony, my main concern was the sudden drop from +8 to -10. If it stopped at 0 I would feel more confident. When it does this it is not a gradual decline, it snaps back to -10.
