Just wondering.When the smoke started appearing, was your car started (ignition key at the "On" position) and running or were you trying to start the car (key at the "Start" position). The wire from the voltage regulator joins with the wire from the ignition switch at the ballast resistor and that wire runs back to the ignition switch at Ignition 1. However, Ignition 1 is the circuit used when the engine has started and is running.
