ARMY TM 9-6115-60412 p. PARALLEL Indicator DS35R and SINGLE SET Indicator DS36R (21, Figure 5-2). These lights provide visual indications of the PARALLEL switch positions. Do not touch exposed electrical connection when a source of power such as utility power or another generator set is connected to the load terminals. Death or injury may result from failure to observe this warning. (1) Test See Figure 5-2. When a lamp fails to light when expected proceed as follows. (a) Open the RCM panel by unlocking three oval studs across the top of the panel. (b) Set multimeter to 120 V ac scale and check for presence of 120 V ac at lamp holder (23) terminals. If 120 V ac is not present when lamp should light, check wiring using FO-3 to the lamp. Trace back through main generator circuits using FO-2 until defective wire or Item is found. Replace or replace as required. (c) If power exists at lamp holder (23) terminals, replace lamp (21) with a known good lamp. (d) If known good lamp (21) does not light, replace lamp holder (23). (2) Replace. See Figure 5-2. (a) Remove clear lens (22) covering lamp (21). Remove lamp. (b) Tag and disconnect wires from lamp holder (23). (c) Remove lamp holder (23) from panel by removing attaching hardware. (d) Install lamp holder (23) in RCM panel. Secure with attaching hardware. Connect wiring to lamp holder (23), remove and discard tags. (e) Install lamp (21). (f) Install clear lens (22). q. MASTER Switch S9R (24. Figure 5-2). MASTER switch S9R allows the operator to start or stop the generator set from the remote control module. The toggle switch is spring loaded to return to the RUN position after having been held In either the START or STOP position. (1) Test. (a) Shut down the generator set. See Figure 2-23. (b) Open the RCM panel by unlocking three oval studs across the top of the panel. (c) Disconnect negative leads from MASTER switch S9R (24) terminals 3 and 4. NOTE Do not remove jumper across terminals 2 and 6. (d) Set a multimeter to RX1 scale with MASTER switch S9R in RUN position, test for continuity across terminals 1 and 2 and 5 and 6. Multimeter should indicate 0 ohms. (e) Hold MASTER switch S9 in START position. Multimeter should indicate zero ohms across terminals 2 and 3 and 5 and 6. (f) Hold MASTER switch S9 In the STOP position Multimeter should indicate 0 ohms across terminals 1 and 2 and 4 and 5. (g) Connect negative leads to terminals 3 and 4. (h) Replace MASTER switch S9R (24) if It falls any test described above. 5-24
