Cranking Test
- Using a battery load tester, connect positive and negative leads to battery. Connect inductive ammeter pick-up to positive battery cable. Disable ignition system. See DISABLING/ENABLING IGNITION SYSTEM.
- On all models, ensure all lights and accessories are off. Place A/T in Park position or M/T in Neutral position. Apply parking brake. Crank engine and observe voltmeter reading. If voltage reads more than 9.6 volts and ammeter reads more than 250-300 amps, proceed to CIRCUIT RESISTANCE TESTS. If voltage reads 12.4 volts or more and amperage reads 0-10 amps, proceed to SOLENOID TEST.CAUTION: During cranking, DO NOT draw battery voltage down to less than 9.6 volts. Use care not to overheat starter.
- If starter cranks engine freely, but problem with starter is still suspected, engage starter several times while observing volt/ammeter readings. A starter that has a problem should fail when performing this procedure.
