Chapter 5: Servicing the Lightbar
4. Secure the end bracket to the aluminum extrusion with the ten 5/16" screws.
5. Install the end PCB and end dome as described in "Installing an End Board" on page 29.
6. Reconnect power to the lightbar.
Replacing a Fuse
The control board, which is beneath the passenger-side PCB, has two 15 A automotive mini-
blade fuses to protect the lightbar. The fuse in position F3 is for the passenger side of the lightbar
and the fuse at F4 is for the driver side, if available in your model, and the driver side of the
lightbar. Before replacing a fuse, investigate the cause of the circuit failure.
STATIC SENSITIVE DEVICE
The PCBs can be damaged by an electrostatic discharge (ESD). Follow anti-static
procedures while servicing the PCB.
1. Disconnect power to the lightbar.
2. Use a flat-head screwdriver to remove the two 1/4-20 screws that secure the passenger
side end dome to the aluminum extrusion and remove the nameplate (Figure 3.1 on page
16).
3. Slide the dome off the aluminum extrusion.
4. Use a 5/16" nutdriver to remove the ten hex-head screws securing the end bracket to the
aluminum extrusion.
5. Turn the bracket over to expose the control board.
6. Use needle-nose pliers to pull the fuse straight out off the board.
7. Insert a new fuse of the same type and amperage into the slots and ensure that it is prop-
erly seated.
DO NOT OVERTIGHTEN SCREWS/NUTS
To avoid damage to the lightbar, do not overtighten the screws and nuts.
8. Secure the end bracket to the aluminum extrusion with the ten 5/16" hex head screws.
9. Reinstall the dome.
10. Reconnect power to the lightbar.
