 Table 10 Troubleshooting tips

Problem

Corrective Action

The light bar 

does not light

•  Verify that the light bar’s Red power line (+BAT) and the Black ground- 

power line (–GND) are properly connected to a good, fully charged 

12-volt battery. Check the 40 A fuse.

•  Ensure that the ground connection from the light bar controller to the 

aluminum extrusion is good.

•  Verify that the CAT5 cable is connected to the Serial Interface Module 

(J1) and there are no damaged pins in the sockets.

•  Try a new CAT5 cable.
•  Check the connections on the Serial Interface Module: 

•  The Black wire and the Black/White wire are connected to ground  

(–GND) 

•  The White wire is connected to 12 Vdc. Check the 1 A fuse. 
•  A MODE wire has 12 Vdc.

•  Check the position of Switch 1 on SW-2 in the Serial Interface Module. 

If Switch 1 is down (ON), ensure that the ENABLE control wires (Green/

White and Orange/Black) have 12 Vdc applied.

•  Check the positions of the DIP switches in the Interface Module. 
•  Check the fuses on the mainbar controller.
•  Reset the controller (page 31).

An LED 

module does 

not light

•  Swap the LED board with good board to see if the board is bad.
•  Check the connections of the cable that goes from the light bar controller 

to the LED ROC board.

•  If it is a rear module, check the SignalMaster connections.
•  Reset the controller (page 31).

Half of an LED 

module does 

not light

•  Replace the ROC board that the LED is on.
•  Reset the controller (page 31).

The light bar 

turns off when 

the Flash 

Takedown/

Alley lights 

turn on

•  Ensure that the vehicle battery is fully charged.
•  Verify that the light bar’s Red power line (+BAT) and Black ground-power 

line (–GND) are properly connected to a good, fully charged 12-volt 

battery. 

•  Check the Red power line (+BAT) and the Black ground-power line  

(–GND) connections in the light bar and vehicle.

•  Reset the controller (page 31).
