- Is the voltage greater than 12.5 volts?
- Yes : GO to A2.
- No : REPAIR circuit 1523 (DG) for an open. TEST the system for normal operation.
A2 CHECK THE VOLTAGE TO THE STARTER MOTOR SOLENOID
- Measure the voltage between the starter motor solenoid positive terminal and ground.

- Does the starter solenoid engage?
- Yes : GO to A4.
- No : INSTALL a new starter. TEST the system for normal operation.
A4 TEST THE STARTER MOTOR RELAY
- Carry out the relay component test on the starter motor relay. Refer to RELAY COMPONENT TEST .
- Does the starter motor relay test good?
- Yes : REPAIR circuit 113 (YE/LB) for an open. TEST the system for normal operation.
- No : INSTALL a new starter motor relay. TEST the system for normal operation.
