Amp guage maxed out.

Wiring harness shorted out at the shop and was.......fixed. I was talking to a wiring guy on the phone today where I could explain things much better I'm not a very good reader answerer ...much better on the phone and from what we discussed the best thing I can come up with is take the car in and get a new painless wiring kit put in because of what happened and also because of how old the original is.

So was this a recent incident, in other words had it been running OK for some time after being "fixed?"

I'm not sure I understand why you cannot explain what the mechanic told you. Maybe he dressed things up in bullshit. Did he suggest there are multiple problems he did not fix?

I do understand, however, that old harnesses can have "problems"
