So electrical is not my strong part but I have a multimeter and know enough to be dangerous. Battery is in good shape takes a charge and load tests fine. When I charge it up the tractor fires right up. Checking at the battery posts when running its showing 12 volts, so there is no charging happening. The plug on the back of the Alt was in bad shape, broken and sun burnt. I put new connectors on. Still the same, no charge. with it running I pulled the connector off the back of the Alt and checked the battery spade, at idle it’s showing 14 volts. Ok now what to check? I looked at the wiring diagram and it looks like the only other thing in the line back to battery would be the key switch. i cleaned all the other connections from the Alt to starter with no change. The key switch has three positions, on/lights/lights and in any of these positions the battery shows no charging. Where do I go From here. Thanks in advance.
