Most times it's the starter foot switch that is your current leak.
As for re-polarizing it is not necessary. If you stop and think how many folks use a battery disconnect switch and just connect it and go. The need for polarization usually only occurs when the generator has been removed for repairs or when a reverse current has occured by crossing battery terminals.
