Kw: killowatt unit (for starter output). 100a: 100 ampere output (for alternators). 120a: 120 ampere out (for alternators). 80a: 80 ampere output (for alternators). All orders from Canada will need a phone number.
I bought another starter motor just before I bought this. I had return it due to imcompatible terminals. I assure that this is compatible and working good.
