I agree that the alternator should be checked (probably a bad voltage regulator).
However, electricity does not work that way, JFP.
Electrons have a negative charge, thus they are attracted to the positive "holes" of the positive terminal. In a DC circuit, electrons flow from negative to positive (electrons are pushed away from the negative terminal because likes repel, and attracted to the positive terminal because opposites attract).
However, the direction of current flow in any part of a given circuit is unknown and only theoretical. You can calculate the net charge of a complete circuit, but the actual directional flow of current within the circuit is completely unknown. Any electronics engineer knows this
That said, electronic circuits are designed with the flow of negative to positive in mind, so reversing the polarity can and will damage things.
1) possibly
2) very likely
3) less you had a hook up that way for a long time, no.
4) I believe you are referring to the gym points in order to pop the funk in the case of a dead battery...?
Check all of your fuses.
