Just shows how little I know about electrics
So in this picture, the black wire (circled red) goes onto one of the gearbox bolts? Are the positions of the thick red wire (circled yellow), and small red/black wire (circled blue) correct?
Then for the battery connections in this picture, the medium thickness black wire that comes from the negative terminal (circled red) should be bolted to the chassis and I remove the small wire going from the chassis to gearbox (circled blue)? Or should the wire go from chassis bolt to head (blue circled one)?
