It all started with an intermittent flash of the alternator light. Most recently, in a 1/2 hr drive, it might blink 4 or 5 times, quick blink on, then off again. Meanwhile my dash voltage gauge is pegged. Have yet to follow the wires to see exactly where it's connected (it's not OEM).
So I hooked up a DPM reading directly off the battery at the firewall junction post, ground at the ground of the isolator. Most of the time in the 1/2 hr 55mph drive, it is about 13.6v, sometimes 13.8; but at least once it went erratic, and bounced around from 14v to 16v. Is this just a loose connection or is this an intermittent failure mechanism going on? (Erratic meter didn't coincide with light flicker.)
Thanks for your help.
