TM 5-6115-593-12 TO 35C2-3-463-1 Table 5-3. Remote Control Module Troubleshooting (Organizational Level)-Continued MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 5. VOLTS AC METER DOES NOT INDICATE CORRECT VOLTAGE. Disconnect cables to remote control module and, using a multimeter, check for continuity across the terminals of VOLTMETER select switch S101 as it is set to each position. If multimeter does not read zero ohms when particular position is closed and infinite when open, the switch should be replaced. 6. AMMETER DOES NOT INDICATE CORRECT CURRENT. If feasible, disconnect cables to remote control module and, using a multimeter, check for continuity across the terminals of AMMETER select switch S102 as it is set to each position. If multimeter does not read zero ohms when particular position is closed and infinite when open, the switch should be replaced. 7. WHEN OPERATED, FREQ ADJ SWITCH DOES NOT AFFECT OUTPUT FREQUENCY OF GENERATOR SET. Set 24V DC CONTROL CIRCUIT BREAKER (on generator control panel) to OFF and, using a multimeter, check for continuity across terminals of FREQ ADJ switch S5 as it is toggled to each position. If switch does not read zero ohms in one position and infinite in the other it should be replaced. 8. WHEN OPERATED, VOLT ADJ SWITCH DOES NOT AFFECT OUTPUT VOLTAGE OF GENERATOR SET. Set 24V DC CONTROL CIRCUIT BREAKER )on generator control panel) to OFF and, using a multimeter, check for continuity across terminals of VOLT ADJ switch S6 as it is toggled to each position. If switch does not read zero ohms in one position and infinite in the other it should be replaced. 9. GENERATOR SETS DO NOT LOCK INTO OPERATION WHEN SWITCHED TO THIS MODE. Set 24V DC CONTROL CIRCUIT BREAKER (on generator control panel) to OFF and, using a multimeter, check for continuity across the terminals of PARAL LEL OPERATION switch S8 is toggled to this position. If switch does not read zero ohms in one position and infinite in the other it should be replaced. 5-9
