I don’t know about a 1984 with the kf82 so maybe take this with a grain of salt

But I know on the newer style with the FE290 the ground wire from the generator runs to the frame rail right above the starter gen. It’s pretty short and when you do a lift kit it drops the engine lower and can break that ground strap off the frame above it.

Worth a quick check anyway. If that’s not it, then need to verify power is making its way to the starter when you press the pedal and verify the ground wire on the S/G as well
