Reflector/Flash Tube Assembly
Replacement.
WARNING
High voltages are present inside the lightbar.
Wait at least ten (10) minutes, after shutting
off power, before servicing this unit. Failure
to do so may result in property damage, seri-
ous injury, or death to you or others.
Disconnect ALL power to the lightbar before
any maintenance is performed.
As strobe lights are used, flash tubes begin
to darken, causing the light output to decrease. Also,
as flash tubes age, they may have a tendency to
misfire (not fire periodically).
After extended operation, occasionally
check for flash tube degradation. Should the tube
misfire, have a noticeable decrease in light output,
glow continuously, or darken excessively, it should be
replaced.
NOTE
Not replacing the reflector/flash tube assem-
bly when any of the above conditions exist
could cause a break-down of other power sup-
ply components.
To replace a reflector/flash tube assembly,
proceed as follows:
1.
Unplug the reflector/flash tube
assembly’s connector from the wiring harness.
2.
Remove and retain the two #8 thread-
forming screws which secure the reflector/flash tube
assembly.
3.
Install the new reflector/flash tube
assembly (Part No. 8552443) by performing the
previous steps in reverse order.
