Good question: "If the wire from the ammeter to the "batt" is hot, will that make the wire going to the "A" hot and make the generator try to run like an electric motor?
NOOOOOOOOO NOT NORMALLY UNLESS THE CUTOUT RELAY INSIDE THE VR IS BAD AND STUCK CLOSED.
The Cutout Relay between the VR's BAT and ARM is normally open and only closes once genny is spinning fast enough and producing sufficient voltage.
If alls well when the tractor isn't running the VR's cutout relay is OPEN so theres no hot voltage on its ARM terminal so the genny wont try to spin. BUT if the VR is bad and relay is stuck closed YES there will be hot voltage on the VR's ARM terminal which is wired to the gennys ARM post and it will try to spin like a DC motor.
The design is ONLY once a good working genny spins fast enough will the cutout relay close so the gennys output can get to and charge the battery......
