TM1O-393O-66O-2O Table  2-2. Electrical Troubleshooting (Cont’d) MALFUNCTION TEST OR INSPECTION CORRECTIVE  ACTION l Result of #89 starter solenoid voltage drop test should be less than 0.3 volts.    Result of #71 starter current average test should be between 0 and 250 amps. l Result of #72 starter current first peak test should be between 300 and 1000 amps. If test parameters are not met, check for loose or corroded connections at battery and starting motor. Inspect, clean, and tighten all connections as required. Step 3. Check for proper engine oil. Verify oil weight with oil sample (TM10-3930-660-10). If  incorrect, drain and add correct oil. (see LO10-3930-660-12). 4. STARTER MOTOR KEEPS RUNNING Step 1. Check for defective starter switch or short in wiring harness. Test starter switch and wiring harness for continuity, para. 8-46 and 8-47. Repair or replace as necessary, para. 8-9, 8-46, and 8-47. Step 2. Check for defective starter relay. Test starter relay for continuity. Replace if defective, para. 8-22. GAUGES  AND METERS 5. ALL GAUGES AND HOURMETER DO NOT WORK Step 1. Check if circuit breaker (CB1) is tripped l The circuit breakers will trip if there is a shorted or grounded wire. . The circuit breakers will automatically reset after cooling. They cannot be reset manually. l Under  normal  operating  conditions,  circuit  breakers  should  never require replacement. However, if a circuit breaker does not reset after it has cooled, the circuit breaker is defective and must be replaced, para. 8-12. 2-14
