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 A/T in Park or M/T in Neutral. Apply parking brake.
- Crank engine and observe voltmeter reading. If voltage drops below 9.6 volts, recharge and test battery. If voltage remains above 9.6 volts, observe amperage reading. Replace starter if amperage draw is more than specified. See STARTER SPECIFICATIONS.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.
