73' duster wont start after dropping steering column

One problem here is that we have different goals.
You just want to start the car, I'm trying figure out what went wrong so it can be addressed and doesn't happen again.

the ampmeter pegged to the right.

And how could this happen?


This is a big clue. It tells you which way to look.

A. Power only comes from the alternator or the battery. Now we know it was coming from the alternator.

B. We know the engine kept running "drove to the next exit" hence the observation
that's just what was going back to the battery.

This narrows it down a lot. Only a few situations that can draw that much current through the ammeter toward the battery. (such as very high voltage, busted battery, short between battery and ammeter, stereo wired to battery that shorted, etc)
You observed smoke from location(s) you know, and had a stereo that got very hot that is wired to a location you know.

Fill in the rest of the story and I think you will know where to look.
