Cranking Test
NOTE:
Ensure engine is at normal operating temperature. High viscosity oil, extreme cold temperatures, or tight engine will increase amperage draw.
- Using a battery load tester, connect positive and negative leads to battery. Connect inductive ammeter pick-up to positive battery cable. Ensure all lights and accessories are off. Place automatic transmission in Park, or manual transmission in Neutral. Apply parking brake. Remove Automatic Shutdown (ASD) relay from Power Distribution Center (PDC). Refer to PDC cover for relay location. PDC is located in engine compartment. On manual transmission models, depress clutch pedal.CAUTION: During cranking, DO NOT draw battery voltage down to less than 9.6 volts. Use care not to overheat starter.
- On all models, crank engine and observe voltmeter reading. If voltage drops to less than 9.6 volts, recharge and test battery. Retest voltage. If voltage remains at less than 9.6 volts, bench test starter. See BENCH TESTING . If voltage remains more than 9.6 volts, observe amperage reading. If amperage draw is less than specified, perform circuit resistance tests. See STARTER SPECIFICATIONS . Also see FEED CIRCUIT RESISTANCE TESTS .
- If voltage reads more than 12.5 volts, and starter does not turn, problem is in battery, starter relay, starter solenoid, ignition switch, park/neutral switch, clutch switch or wiring. Check each component until problem is found. If voltage is more than 12.5 volts and starter cranks very slowly, perform circuit resistance tests. See FEED CIRCUIT RESISTANCE TESTS .
