A wire getting hot almost certainly means a bad connection. Yuo need to clean all of your main gonnections, both positive and negative, at the batteries, to the motor & starter and to the body as well. You should also clean the alternator connections.

While you are at it you should check and charge both batteries.

It may not be that wire either that is the problem there should be another else where, but now the wire you have found is doing the work for 2, instead of just is own.. just a thought.
