3. At the starter switch off
Starter motor started off
After the starter switch turned to off, and the main switch in the state open (yet free from contact plate). The flow of current is as follows:
Battery - terminal 30 - play switch terminal C - Field coil - anker - mass
Because the starter switch is turned off then the pull-in coil and hold coil does not get in the flow of the terminal 50 instead of terminal C so that the current flow will be:
Battery - terminal 30 - play switch - terminal C - Pull-in coil - hold-in coil - mass
Since the current pull-in coil and hold coil in the opposite direction of the magnetic force generated is also opposite each other so that both eliminate, this resulted in the return spring force can restore the contact plate to its original position. Thus the drive clutch lever and pull the starter pinion gear apart from docking.
