The self exciting regulator was supposed to be set at 14.7v, it's been running the high voltage for 2 months. I don't know if the cluster is even right. I need to put in an actual gauge.
That brown exciter wire that didn't work I could not figure out and neither could the guy that had the truck before me, which is how I got the truck for $500. I thought it would be an easy fix and couldn't pass it up, but I was wrong.
I know that the voltage is way too high, not sure how to fix it. The truck doesn't have a stereo (afraid to put one in until issue is fixed), no shift cable because it's a 5 speed and doesn't have cruise control. The ecm part worries me tho.
My battery ground is going to the frame. There's no grounds to the engine.
