No, I don't have a battery hooked to the voltage limiter. The limiter plugs into the back of the instrument panel which has been removed from the car. Just for kicks I probed the disconnected blue wire that goes back to the tank and to my amazement there was a pulsating voltage on it with the ignition on! It just didn't seem to ring true with what I was seeing on the wiring diagram to have voltage on that wire when the limiter was disconnected and removed from the car.
