(3)
Light and Wire Assembly Test.
(a)
Remove 16 screws (1, figure 4-5), lockwashers (2), and flat washers (3) from switch box panel (4) and pull
panel forward.
(b)
Set multimeter for continuity test.
(c)
Test wires (11) and socket (12) associated with GEN 1 indicator light by testing for continuity between
switch terminal (6) A2 and socket XDS1 and switch terminal A1 and socket XDS1. If multimeter does not
indicate continuity exists on both of these wires, replace light and wire assembly (paragraph 4-23b).
(d)
Test wires and socket associated with GEN 2 indicator light by testing for continuity between switch
terminal B2 and XDS2 socket, and switch terminal B1 and socket XDS1. If multimeter does not indicate
continuity exists on both of these wires, replace light and wire assembly (paragraph 4-23b).
(4)
Cable Assembly Test.
(a)
Remove 16 screws (l, figure 4-5), lockwashers (2), and flat washers (3) from switch box front panel (4) and
pull panel forward.
(b)
Set multimeter for continuity testing.
(c)
Set switch box rotary switch (5) to GEN 1 position and locate power cable assembly (13) associated with
switch position.
(d)
Test white wire by touching one probe of multimeter to load terminal LO on generator set and touching
other probe to load terminal (8), associated with white wire, on switch box. Multimeter must indicate
continuity between these points.
(e)
Repeat step (3) for black wire (between L1 on generator set and Al on switch), red wire (between L2 on
generator set and A2 on switch), and blue wire (between L3 on generator set and A3 on switch).
(f)
Test the ground wire (14) by disconnecting the ground wire that runs from generator to skid mount ground
stud; disconnect wire at skid mount. Test for continuity between free end of wire and ground stud El,
EQUIPMENT (FRAME) GROUND (15), on switch box.
