I know I have seen the answer on a previous thread but could not find it. With the motor turned off, I turn the head lights on and the Amp gauge shows charge instead of negative. Do I have something miss wired or a ground somewhere.
Just switch the wires at the ammeter posts. That will set it correct.
Is your battery hooked up negative ground as it should be? If so, swap the wires on the back of the ammeter and you should be OK.
