TM 9-4910-663-34 Table 2-5. TROUBLESHOOTING (Continued) MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION indicate 10 volts. If meters fail to indicate 10 volts, replace DC VOLTMETER OUTPUT VOLTAGE SELECT switch S11. Step 12. Set circuit breaker CB1 to OFF position. Connect external DC voltmeter to DC VARIABLE VOLTS OUTPUT binding posts, observing polarity. Connect a test lead from positive (red) DC VARIABLE VOLTS OUTPUT binding post to positive (red) EXTERNAL DC VOLTAGE INPUT binding post, and connect another test lead from negative (black) DC VARIABLE VOLTS OUTPUT binding post to negative (black) EXTERNAL DC VOLTAGE INPUT binding post. Set DC VOLTMETER OUTPUT VOLTAGE SELECT switch S11 to EXT position. Set circuit breaker switch CB1 to ON position and adjust DC VARIABLE VOLTS 0-32 VDC control to provide 10 volt indication on external DC voltmeter. Then, change external DC voltmeter connections to calibration jacks below DC VOLTMETER OUTPUT VOLTAGE meter M2, and check to see that both meters indicate 10 volts. If meters fail to indicate 10 volts, replace DC VOLTMETER OUTPUT VOLTAGE SELECT switch S11. 9. BATTERY CHARGE CIRCUIT a. BATTERY CHARGE CIRCUIT INOPERATIVE. Step 1. Check to make sure that all batteries are disconnected from battery compartment battery terminals. Check to see that CIRCUIT BREAKERS CB2 DRIVE CONTROL circuit breaker, CIRCUIT BREAKERS CB5 RELAY CONTROL circuit breaker, CIRCUIT BREAKERS CB6 AC BATT. CHG. circuit breaker, CIRCUIT BREAKERS CB8 DC BATT. CHG. circuit breaker, and CIRCUIT BREAKERS CB11 DC circuit breaker are all set to ON position. Set circuit breaker switch CB1 to ON position. Set BATTERY CIRCUIT SELECTOR switch S6 to 24V position. Set DC VOLTMETER OUTPUT VOLTAGE RANGE switch S12 to X2 position, and DC VOLTMETER OUTPUT VOLTAGE SELECT switch S11 to BAT position. Set MASTER LOAD DISCONNECT switch S8 to ON position. Adjust CHARGE TIMER (MINUTES) control TD1 to 5 minute position and BATTERY CHARGE CIRCUIT control T3 to maintain 12 volt indication on DC VOLTMETER OUTPUT VOLTAGE meter 2-39
