I have to-20 6v pos ground system. I just installed new voltage regulator. I checked continuity on all wiring leading to voltage regulator- no issues. I jumped "battery" terminal on voltage regulator to "generator" terminal on voltage regulator before starting it. When I turn lights on with tractor running amp meter reads -10. When I turn lights off amp meter reads 0. It never goes to charge side, low idle or high throttle speed. Voltage across battery terminals with tractor off is 6.2v; and it is 6.2 tractor running. I took one of the battery connectors off( the + ground off with the tractor running at high throttle and the tractor died. Is this a conclusive test that the generator needs to be rebuilt?

I think you need to polarize the regulator. Most of us putting new regulators in have had the same problem, no charge. Use the link to polarize the system all you need is a jumper wire.

Let us know how you make out. With lights on and generator running you may only see a slight charge. Lights off better

Thanks Tom
I found a short in a wire in the lighting system, tightened all connections to voltage regulator and I changed an in-line fuse, pulled the lights on for at least 30 seconds and when I turned them off the voltage regulator and generator began to talk with each other. The ammeter was showing a charge on the plus side which the battery was in need of. I have my fingers crossed and am happy.

One thing often overlooked, the regulator base needs to be well grounded.

Sometimes paint or rust needs to be cleaned away.
