Cold Cranking Test

For complete circuit diagrams, see WIRING DIAGRAMS  . The battery must be fully-charged and load tested before proceeding.

1. Connect a suitable volt-ampere tester to the battery terminals. See Fig 1 . See the instructions provided by the manufacturer of the volt-ampere tester being used.

2. Fully engage the parking brake.
3. Place the automatic transmission gearshift selector lever in the Park position.
4. Verify that all lamps and accessories are turned off.
5. To prevent the engine from starting, remove the Automatic ShutDown (ASD) relay. The ASD relay is located in the Power Distribution Center (PDC), in the engine compartment. Refer to the fuse and relay layout label affixed to the underside of the PDC cover for ASD relay identification and location.
6. Rotate and hold the ignition switch in the Start position. Note the cranking voltage and current (amperage) draw readings shown on the volt-ampere tester.

1. If the voltage reads below 9.6 volts, see STARTER MOTOR  under COMPONENT TESTING. If the starter motor is OK, see appropriate article in ENGINES. If the starter motor is not OK, replace the faulty starter motor.
2. If the voltage reads above 9.6 volts and the current (amperage) draw reads below specifications, see FEED CIRCUIT TEST  under SYSTEM TESTING.
3. If the voltage reads 12.5 volts or greater and the starter motor does not turn, see CONTROL CIRCUIT TESTING  under SYSTEM TESTING.
4. If the voltage reads 12.5 volts or greater and the starter motor turns very slowly, see FEED CIRCUIT TEST  under SYSTEM TESTING.
