PINION PROTRUSION LENGTH
1. Compare movement “L” in height of pinion gear when it is pushed out with magnetic switch energized and when it is pulled out by hand until it touches stopper.
2. Connect 12V battery and ammeter to starter motor as shown in the figure. Check no load current with pinion gear driven out and starter motor operating.
