Put a working battery in my Super A today and got the tractor running. I turned on the lights and the ammeter showed a discharge. I polarized the generator per John T's instructions:

To Polarize the Generator, first temporarily dead ground the Gens Field post to case/frame, then momentarily flash jump a wire from the Cutout Relay or VR's "BAT" terminal over to its GEN (or ARM) terminal and you ought to get a small spark. Same things accomplished by momentarily flash jumping a hot wire (BAT terminal on Cutout Relay or VR or starter post etc) direct to the Gens ARM post to get the spark.

I was getting 6.3 volts at the battery with my multimeter but when I throttled her up, the voltage didn't increase. It' stayed at 6.3 volts and the ammeter never showed a positive charge. It just stayed on zero. I even had the lights on for quite a while and still showed no positive charge on the ammeter.

I then temporarily grounded the generators's Field post to the case to see if it showed a charge then. But it didn't. After that, I just removed the generator and voltage regulator and brought it back with me. I'll have it tested at shop that specialized in that. Hopefully they'll find the problem. I don't think the problem is in the ammeter.

Thanks for the help guys,
John
