So the original ammeter had a crack in the glass so I wanted to replace it. Never really seem like it did anything anyway. I ended up replacing all the wiring from the generator back. Cleaned all the connections. Wired up the switch. And it fired right up, but the ammeter does nothing. I found the wiring diagrams on here and wired it as it should. From the battery to one side and the battery terminal on the generator as well as the fuse connection from the switch to the other side. I ran The F connection on the generator to The resistor on the bottom of the switch. As per some advice on here I ran a ground wire from the switch before the resister that the F wire is connected to, To A starter bolt. Tractor runs fine and it does not die after working it so I believe the generator is working but I don't know how to test how much it actually putting out. If anyone can help me I'd really appreciate it.
