Cranking Test
- Using a suitable volt-ammeter-load tester, connect positive and negative leads to battery, and inductive ammeter pick-up to positive battery cable. On all models except 3.3L and 3.8L, disconnect ignition coil secondary wire from distributor cap and connect coil wire to ground. On 3.3L and 3.8L models, disconnect coil pack electrical connector at coil pack. See Fig 1.
- On all models, ensure all lights and accessories are off. Place A/T in Park or M/T in Neutral. Apply parking brake. Crank engine and observe voltmeter reading. If voltage reads less than 9.6 volts and ammeter reads more than 250 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.
- Recharge battery as required, after starter tests have been completed. Disconnect all test equipment. After starter problems have been corrected, install secondary coil wire to distributor cap, or reconnect coil pack connector on 3.3L and 3.8L. See Fig 1. Start vehicle several times to ensure problem has been corrected.
