If you want the engine to run backwards, rewire the starter to reverse rotation when engaged and change the cam.
Engine will then run backwards.
Good on Marine applications with twin engines.

Starter doesn't care about polarity. But don't forget your lights. They care about amount of volts.

Never worry about a stupid question here. Always safer to ask than wreck something

NO, it won't, starter drive will simply "overrun" and won't engage or crank the engine.
