has anyone out there besides mr haynes got a simple wiring diagram for a simple bloke? ive just grafted a solienoid from a biger stater, with slightly diffferant bolt on fastenings, bench tested works fine! only when i connect it to the vehicle and attach the wires solenoid kicks in starter fires off, only it keeps going till i yank the battery lead off, then put it back on. what have i wired up wrong?
