CIRCUIT OPERATION
The [1][2]Power Distribution Center (PDC) supplies battery voltage to the engine starter motor solenoid on circuit T40 when the coil side of the engine starter motor relay energizes.

Circuit A0 from the battery is double crimped at the positive battery post. One branch of circuit A0 (battery positive cable) connects to the starter motor. The other A0 branch supplies voltage to a bus bar in the PDC. Fuse B (30 amp) connects to the bus bar and protects circuit C26. Circuit C26 splices to circuit A0 which connects to the contact side of the starter motor relay

The ignition switch supplies battery voltage to the coil side of the engine starter motor relay on circuit A41 when the key is moved to the START position and the [1][2]PARK/NEUTRAL switch is closed. Ground for the coil side of the starter motor relay is supplied by the case grounded PARK/NEUTRAL switch. Circuit T41 connects the coil side of the relay to the PARK/NEUTRAL switch.

When the starter motor relay energizes and the contacts close, circuit T40 supplies battery voltage to the starter motor solenoid. Circuit A0 from the battery supplies voltage to the starter motor when the solenoid energizes.
