battery cable to solenoid connection. If reading is (b) If resistance tests do not detect feed circuit failures, replace the starter motor. DIAGNOSIS AND TESTING - FEED CIRCUIT NOTE: The following results are based upon the The following procedure will require a suitable volt-ampere tester (Fig. 1). CAUTION: Before performing any starter tests, the (1) Check battery before performing this test. Bat- tery must be fully charged. (2) Connect a volt-ampere tester to the battery ter- minals. Refer to the operating instructions provided (3) To disable the ignition and fuel systems, dis- connect the Automatic Shutdown Relay (ASD). The (4) Verify that all lights and accessories are OFF, and the transmission shift selector is in the PARK CAUTION: Do not overheat the starter motor or (5) Rotate and hold the ignition switch in the START position. Observe the volt-ampere tester (Fig. • If voltage reads above 9.6 volts, and amperage draw reads above 280 amps, check for engine seizing • If voltage reads 12.4 volts or greater and amper- age reads 0 to 10 amps, check for corroded cables • Voltage below 9.6 volts and amperage draw above 300 amps, the problem is the starter. Replace (6) After the starting system problems have been corrected, verify the battery state-of-charge and SPECIFICATIONS TORQUE DESCRIPTION N·m Ft. Lbs. In. Lbs.
