  1. can second battery if bad drain main battery? YES

    A shorted battery that is connected will be a short in the entire circuit. A short is a short and will drain everything given time.

    Replace the Second battery and you should be good. This is assuming you haven’t recently installed any new wiring for a sound system or security system, etc.
