[quote=“theShoe” post=60767][quote=“turbo329is” post=59949]Problem: Alternator is inop after removing the factory cluster.
Solution: The alternator has to be energized at startup by the battery idiot light circuit or rewired into an ignition on(green wire) or relay.[/quote]
Boy I wish I had know this 12 months ago when building our replacement car. Took seven months before BTM Motorwerks figured this out for me. Dead batteries and replacing an alternator were no good. Wasted time and money, arghh.
We tapped the blue wire in the gauge cluster harness and all works fine until this past sunday when a bunch of the wires right at that spot where we tapped in burnt up! When this happened the Shift light began to dimmly glow and the tach (aftermarket) bounced around and the motor cut out. Thought I blew the motor.
Maybe the wires burned up because we did not use a resistor or Diode???[/quote]
Give me a buzz/email. I spoke to Jeff about your wiring issues. Gotta be very careful what you tap. A 15ohm resistor between pin 15/16 with shrink is all you need.
