3) Wiring on the starter motor, I have a black lead attached to the terminal closest to the chassis which has a terminal ring and rubber boot on the other end. Any ideas where is meant to go. looking at it there are 2 brown leads in the car wiring harness attached to the chassis and the red power lead from the battery that is meant to attach to this terminal of the starter motor, am i correct ? should i disregard the current attached lead? Commonly used wiring colours. That thick black lead is the earth lead that takes the high current from the starter. It needs to go to the chassis or the battery earth terminal. Jonathan
