THE USE OF HEAVY WEIGHT ENGINE OIL WILL ALSO INCREASE STARTER AMPERAGE DRAW. STARTER MOTOR DIAGNOSIS AND TESTING - STARTER MOTOR Correct starter motor operation can be confirmed by performing the following free running bench test. (1) Remove starter motor from vehicle. Refer to Starter Motor Removal and Installation. (2) Mount starter motor securely in a soft-jawed bench vise. The vise jaws should be clamped on the (3) Connect a suitable volt-ampere tester and a 12-volt battery to starter motor in series, and set (4) Install jumper wire from solenoid terminal to solenoid battery terminal. The starter motor should operate. If starter motor fails to operate, replace (5) Adjust carbon pile load of tester to obtain free running test voltage. Refer to Specifications for (6) Note reading on ammeter and compare reading to free running test maximum amperage draw. Refer (7) If ammeter reading exceeds maximum amper- age draw specification, replace faulty starter motor STARTER SOLENOID This test can only be performed with starter motor removed from vehicle. (1) Remove starter motor from vehicle. Refer to Starter Motor Removal and Installation. (2) Disconnect wire from solenoid field coil termi- nal. (3) Check for continuity between solenoid terminal and solenoid field coil terminal with a continuity VA STARTING SYSTEM 8F - 33 |
