what wires should be goin to the starter motor on my m30 engine?
i've got one that goes direct the the battery, one into the loom then there's two wires goin onto the small threded stud, should i have one or two here??

haynes manual wiring diagram shows there should just be three wires in total goin to the starter motor, can any1 help. i'm killing starter motors !!!!!!!!

cheers

The large stud with a wire going direct to the battery should also have a large wire on it that goes to the alternator.
The yellow/black wire goes to the small terminal on the solenoid, and the green/black unloader wire will have to be connected to the inner large stud.

i've just been looking at my wiring, the black/green wire, what does it do exactly and if it's not connected what happens to the motor??

both the bk/y and bl/gr where on the same post, just removed the bl/gr and the ring terminal has come off. any ideas?

Nothing happens to the starter motor if the black/green isn't connected - just that your windows, roof, heater fan and door mirrors won't work.
The E30 starter motor has a seperate terminal for the black/green wire, but I understand this is absent on the M30 motor. In this case, it should be connected to the inner large stud; the one that has a short link to the motor itself.

oh ok,

thanks alot Brian.
