(2) Function of motor stopper
1. Before engine starts
SG06033E
1) Before starting engine, the contact ACC of starter switch is kept open, and so excitation current
will not be sent to motor stopper relay so that the interior contact is positioned at the condition
shown in Fig a.
2) When the contact plate inside the motor stopper assembly is positioned shown in Fig a, there is
electrical conductivity between connector No.6 terminal and No.2 terminal. Accordingly, battery
voltage will be applied to motor stopper relay No.5 terminal.
