Super A charging system

gonoles6100 · Apr 30, 2011

Were all Super A's 6v positive ground? I figure they were. It looks to have the original style generator and regulator, but the battery is hooked up neg ground. The starter turns and the lights work and the engine runs, but it does not charge the battery. With the tractor off, if i turn the lights on, the ammeter goes to charge not discharge like I would expect. Also, when I pull the ignition switch out, it goes slightly to charge instead of discharge. Is the battery hooked up wrong? I just got this tractor today, and the battery was that way. Im used to my 6v's being positive ground, so its kinda making me wonder.

Yes they all were positive ground and by hooking it backwards, negative ground your gauge will real just like you say, backwards. I would turn it around and then polarize generator. Do this by touching battery terminal to gen terminal(just a flash is all it takes) at cutout or regulator which ever you have. This may solve your charging problem or then again it probably won't. If it doesn't charge, you can ground the field terminal and if it charges then you know gen is ok and grouding of the field is problem. I you have high low charge position on light switch the field is supposed to ground directly on high charge and through a resistor on low charge. If you have a regulator then that would be the problem. Pitted or burned points or maybe reglator itself not grounded.

pete 23 just gave you a good answer how to do it.
