You nailed it! 10.9 ohms from switch to alternator unplugged. Yes I have been testing the voltage with the plug installed on the alternator. Ok, now we are getting somewhere! I have 12 volts on the brown wire at the alternator with the connector unplugged. So from the switch to the alternator I have 12.67 volts. So what could be causing the voltage drop when I plug the connector into the alternator? So let me guess, this is normal with the plug connected and I've been chasing rabbits?
