I wanted my battery light to work on the dash, which doesn't with a one wire alternator, so I added the attached gizmo to my alternator and wire harness, but I couldn't turn the engine off and had to yank the coil plug.

Ah, so it's a dual mode alt. Yes, PowerMaster uses a regulator that works as either a 1 wire or a 3 wire, even if they only list it as a 1 wire.

Instead of running the 'red wire' to the back of the post on the alt, run it to the common post. That is your voltage sensing wire.
