Generator Light

[65GMCFirstride]

We just got the 65 GMC running this weekend after 10 months of restoration. I will share some photos soon.

The Generator light stays on while driving. I figured out from the forum that it is either not charging or it is a grounding issue. The PO installed a single wire alternator and jumped 1 and 4 on the voltage meter.

I check the voltage at idle and it was 14.1 I did an ohm test from the negative terminal to the alternator casing and it showed good continuity. I verfied continuity on the frame, block, and firewall. I assume that verifies that I have a good ground.

So, any other suggestion on what I should do. I hate to simply pull the bulb.

Thanks!
