Circuit 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 jumper wire between coil wire and 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 below 9.6 volts and ammeter reads more than 250 amps, proceed to CIRCUIT RESISTANCE TEST . If voltage reads 12.4 volts or more and amperage reads 0-10 amps, proceed to SOLENOID ON-VEHICLE TEST .CAUTION: DO NOT overheat starter or draw battery voltage less than 9.6 volts during cranking.
- If starter cranks engine freely at times, 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.
- After starter problems have been corrected and test completed, charge battery as required. Disconnect all test equipment. Remove jumper wire from secondary coil wire. Reconnect coil wire (coil pack connector on 3.3L and 3.8L). Start vehicle several times to ensure problem has been corrected.
