Tried searching for threads on this but turned up almost nothing under bouncing alternator gage, so having to post my own.
66 Satellite Hemi I just got started today after replacing all of the harness except the rear one, and a whole lot of other stuff. Standard round back alternator, professionally rebuilt and bought from a forum member. Old, black voltage regulator that I haven’t changed out. Haven’t done any voltage checks as I’ve been concentrating on getting the distributor positioned to where I can time it. I dragged the battery down pretty good before finally getting it to start and the gage was showing pretty much full charge but it was gradually coming down as it ran - all that looked perfectly normal. But then I started noticing twitches in the gage needle - always dropping towards the middle of the gage and then back to wher3 it was showing to be charging. No bounces to full scale - just fro mid-point charging position to middle of gage (no charge) and back. The bounces are random and will sometimes stop for a bit and then resume in random fashion.
Does any of that sound familiar. I will double check the mount screws and run a separate ground. Probably need to just find a solid state regulator to put in it?? Any other things to check?
