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.
