OK, so from the terminal to the field coil, then to one of the brushes, through the commutator to the other brush and then to the casing, completing the circuit. Yes?

McCabe-Thiele (Ted):
Okay the body of the starter motor when bolted to the crankcase is one side of the connection that must mean to avoid a dead short the bolt that connects the starter cable must be insulated from the motor outer casing.

Bryanj:
Thats correct. If you look at the brushes one tail(correct name for that wire) is crimp connected to a field winding, which mskes it a bugger to change as you have to cut the existing tail leaving a short bit and solder the new one too it. The other brush bolts on

oldchuffer:
As a footnote i replaced the terminal bolt, fashioned a new insulator and soldered the field wires back on, all good  :)
Thanks all for all your help on this query.
