So i purchased a wiring harness from rebel wiring. Anyways, the harness has a "alternator excitor" wire. I am assuming this supplies 12 volts (or 14) when the accessory bus is energied I.e. when the ignition is in run. I didn't want to damage anything as the voltage regulator would only sense 12 volts once the key is off start. It would "see" no volts until I let go of the key. Is this an issue?
