Electrical Help Needed - Big Time

"Started the car today" unquote.
So what work has been done since the last time it ran ?

Nothing has changed, car has only been running for a week or so. The dash gauge has been high the whole time but this smoke is new to me.
I have driven about 30 miles so far, just a few at a time with no problems, trying to make the distance "comfort circle" a little larger each time LOL.
Runs great other than that.
