I disconnected the wire from the BAT terminal and connected the battery with positive ground. When I touched the wire back on the BAT terminal there was no spark so I screwed it in.
I then momentarily shorted the GEN terminal to the BAT terminal and got my little fireworks show.
I started the tractor and at first it seemed it was not charging. It was the least negative in second from left position. In this position I measured 6.37 volts on the battery. I turned the bright lights on and measured 6.17 volts. Then noticed the ammeter was slightly positive. Put the switch back to second from left and the ammeter needle was on the mark between the middle and "+". Went back and this time measured 8.0 volts at the battery.
I shut the engine off and the ammeter showed negative. The needle was just touching the "-" symbol.
Started it back up and it showed positive charge and 8 volts again.
Shut it off and still a negative charge so I disconnected the battery.
So it looks like we fixed the no charge while running problem and replaced it with a discharge when not running problem.
Any obvious things I should check or should I just replace all the old cracked wiring?
