Servicing the Light Bar Controller
The controller generates and receives the signals that control the light bar’s flash
patterns. If the light bar fails, the problem may be one or more blown fuses. To
replace a fuse, you can remove the controller from the aluminum extrusion without
completely disconnecting it.
STATIC SENSITIVE DEVICE: This light bar circuitry can be damaged by
electrostatic discharge (ESD). Follow anti-static procedures when servicing
this light bar.
Removing the Controller
To remove the controller:
1.
Remove the passenger-side end dome as described in "Removing and Inspecting
the Domes" on page 39.
