TM 5-6115-593-12 TO 35C2-3-463-1 Table 5-2. Remote Control Module Troubleshooting (Operator/Crew Level)-Continued MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 10. AMMETER DOES NOT INDICATE CORRECT CURRENT. Set AMMETER select switch to each position and observe AMMETER indication. If indication is incorrect in all positions of AMMETER select switch, the AMMETER is, most probably, at fault (refer to next higher level of maintenance for replacement). If AMMETER indication is correct in at least one position, refer to next higher level of maintenance. 11. VOLTS AC METER DOES NOT INDICATE CORRECT VOLTAGE. Set VOLTMETER select switch to each position and observe VOLTS AC meter indication. If indication is incorrect in all positions of VOLTMETER select switch, the VOLT AC meter is, most probably, at fault (refer to next higher level of maintenance for replacement). If VOLTS AC indication is correct in at least one position, refer to next higher level of maintenance. single-throw) toggle switches as follows: (a) Operate toggle switch to the ON position. (b) At rear of the panel, remove one lead from the switch. (c) Using an ohmmeter (Rx1 scale), test switch for a closed circuit. If meter indicates an open circuit, replace switch. (d) Operate toggle switch to OFF position. Using an ohmmeter on Rx1 scale, test for open circuit. If meter indicates a closed circuit, replace switch. (2) Test all DPTT (double-pole, triple-throw) toggle switches as follows: (a) With switch in center (neutral) position, check that contacts 1-2 and 5-6 have continuity. Ohmmeter should be set to R x 1 scale. (b) With switch in up (on) position, check that contacts 2-3 and 5-6 have continuity. (c) With switch in down (off) position, check that contacts 1-2 and 4-5 have continuity. (3) Activate ANNUNCIATOR TEST switch (16, figure 2-14) to energize the alarm horn. If alarm does not sound, test switch according to (1), above. If switch is not defective, connect 24V DC across terminals 1 and 2 of alarm horn. If horn does not sound, it is defective and should be replaced. 5-6
