TEST OR INSPECTION
2. ONE OR MORE REEL LIGHTS ARE INOPERABLE.
Ensure FRS 120/208 VAC is functioning properly.
Ensure FRS generator is started for all voltage checks (TM 9-4940-568-10).
Check circuit breaker #10 (1) inside 120/208 VAC control panel (2) is not tripped. If circuit breaker is not
tripped, go to next test.
Reset circuit breaker #10. If circuit breaker #10 will not reset, Notify Supervisor.
Ensure multimeter is setup to check AC volts in the correct range.
Check for voltage at AC outlet on reel light cable at light end.
If voltage is present, remove bulb and check for voltage across bulb sockets. If voltage is
present across bulb sockets, replace bulb. If no voltage is found, replace reel light
If no voltage is found, remove junction box cover and check for voltage on wires 11 and
12. If voltage is present, repair or replace wires 11 and 12 to reel light (see schematic
Figure 2-4). Recheck voltage and if no voltage is found, Notify Supervisor.
