Amp Meter connections
You guys think this is why the car only starts occasionally and was surging? thoughts
I would only go so far as to say it could have been a contributor to electrical issues.
It does and I think that’s a result of the loose, burnt connection. Not a cause.
Hard to say where it started until the ammeter itself is removed but the heat damage seems to be at the wire going into the terminal. However I have theory that someone messed around behind the dash and moved the wires.
The wire routing here looks like someone had been in there and moved the harness and or connectors.

I think the insulation got worn where it was touching the headlight switch. Eventually this
may have caused some occassionally grounding although the copper conductors aren't showing burning in this photo.
The ring terminal on the Red (A1) wire looks to have more corrosion and heat damage than the ring terminal Black (R6A) wire. Again leaves us wondering if that stud got yanked, or there was more water (leak) that landed on it, or the wear on the insulation and conductor led to resistance and heating during recharge.
AFAIK the ammeter wires on models with this instrument panel should be coming along the top of the dash and then over the headlight switch, as shown in this '70 Plymouth Chassis Manual.
How should I joint the two ring connectors? I would rather connect them with a butt connector, but I'm going with a factory ammeter connection later
Do a search here on splices
Heres a couple

But the ring terminal and the lead going into it at minimum needs to be cleaned up.
And all of the other connections still need to be checked.
