Reinstalling the Controller
To reinstall the controller:
1. Insert the four standoffs into the controller.
2. Gently push the controller's standoffs into their holes on the ROC panel until
they lock.
3. Reconnect all wires and harnesses.
4. Turn the PCB over and place it on the two standoffs with the holes in the PCB
centered over the holes in the standoffs. Ensure that the ground wire is not
caught between the edges of the PCBs.
5. Gently push on the PCB until it clicks into place.
6. Turn the ROC panel over and connect the ground wire using the 1/4-inch hex
bolt that you removed in step 2 in "Removing the Controller" on page 44
7. Place the dome over the PCB, ensuring that it is properly seated in the lip seal.
8. To prevent cross-threading, turn the barrel nuts counterclockwise until you hear
a click, then tighten them. See Figure 14 on page 39.
9. Test the light bar to ensure that it operates properly.
