(2)
Replace.
(a)
Perform steps (d) and (e), above, if needed.
(b)
Install horn (12) in electrical box (13). Thread horn wiring through bottom hole of horn assembly and
connect as tagged. Remove and discard tags.
(c)
Secure alarm horn LS1R (12) to the electrical box (13) using mounting hardware.
(d)
Close RCM panel and secure by locking three oval studs across the top of the panel.
(e)

u.
RCM Cable Assembly (34, Figure 5-1). The RCM cable assembly is used for power and control interfacing of
the main generator set with the RCM.
(1)
Test.
(a)
Shut down the generator set. See Figure 2-23.
(b)
Detach the remote control cable (34) from the generator and RCM chassis.
(c)
With multimeter set to RX1 scale, check for isolation between all connector pins. Resistance
reading across each pair of pins tested should be infinite ohms. Also test each pin for isolation from
ground (connector body). Resistance reading should be Infinite ohms.
(d)
Reconnect remote control cable assembly.
(e)
Reconnect remote control cable (34) and wiring harness (see Figure 5-3) If required.
v.
Wiring Harness (Figure 5-3). The wiring harness is used to interconnect the RCM circuits with the main
generator set in conjunction with the connector receptacle and remote control cable.
(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)
Unplug the wiring harness (Figure 5-3) from the connector receptacle (36, Figure 5-1). Set a
multimeter to RX1 scale and test for continuity of each conductor from Its pin to its terminal point
(refer to FO-3) and wiring diagram in this manual. Resistance reading for each conductor tested
should be zero ohms.
(2)
Replace.
(a)
Unplug harness from connector receptacle (36, Figure 5-1).
(b)
Tag and disconnect wires to all components in RCM chassis.
(c)
Remove straps securing harness (Figure 5-3) and remove harness.
(d)
Connect wires on replacement harness to components as tagged Remove and discard tags.
(e)
Plug harness (Figure 5-3) Into connector receptacle (36, Figure 5-1).
(f)
Close RCM panel and secure by locking three oval studs across the top of the panel.
(3)
Repair.
(a)
Remove harness in accordance with step (2), above.
(b)
Disconnect and remove defective wire.
(c)
Connect replacement wire of the same size and type to the terminals from which the defective wire
was removed.
(d)
Secure new wire to harness using tiedown straps.
w.
Replacement of Nameplates and Identification Plates. If any of the nameplates (33, 35 through 48, Figure 5-2)
are damaged to the point of being illegible, remove rivets (34) to remove damaged plate and Install a new plate using
M24243/6-C602H rivets (34).
