TM10-3930-660-20 Table 2-2. Electrical Troubleshooting (Cont’d) — MALFUNCTION TEST OR INSPECTION CORRECTIVE  ACTION Step 3. Check if circuit breaker (CB6) is tripped. . The circuit breakers will trip if there is a shorted or grounded wire. l 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. Step 4. Check for continuity of starter switch between CB6 and neutral safety switch, para. 8-46. Replace starter switch if necessary, para. 8-9. Step 5. Check for broken or disconnected wiring. Check wiring and replace if necessary, para. 8-46. Step 6. Check operation of neutral safety switch. Test safety switch, para. 8-5. Step 7. Check operation of starting relay. Listen to relay for “click”. If click is not heard, check coil continuity, para. 8-22. Replace relay if necessary, para. 8-22. 3. STARTER TURNS ENGINE SLOWLY Step 1. Check for low battery output with STE/ICE. Test battery voltage using STE/ICE #67. Battery voltage should be 24 volts or higher.  Service  or replace batteries as required if voltage is below minimum requirement.   Refer to TM9-6140-200-14. Step 2. Check for proper starting system operation with STE/ICE. Test starting system using STE/ICE tests #68, 69, 70, 71, and 72. l Results of #68 starater motor voltage test should be between 18 and 27.5  volts. l Result of #69 starter negative cable voltage drop test should be between O and 3 volts. l Result of #70 starter solenoid voltage test should be between 18 and 27.5 volts. 2-13
