Troubleshooting using the manual slide

To verify the brake controller is properly wired, follow these steps:
A. Disconnect the tow vehicle/trailer electrical connector. Move the manual slide lever (Figure 1) to
the left. The red indicator light must become increasingly brighter and the tow vehicle stop lamps
must illuminate.
B. If the red indicator light does not illuminate or glows dimly, the tow vehicle has a short to ground in
the trailer brake circuit or the white ground wire is not connected to ground. Check and/or repair
wiring and tow vehicle/trailer connector.
C. If the stop lamps do not illuminate, check the red stoplight wire connection of the brake controller
for connections to the non-powered stop lamp wire of the vehicle stop lamp switch.
D. Connect the tow vehicle/trailer electrical connector.
E. Move the manual lever to the left. The red indicator light must illuminate from dim to bright and the
trailer stop lamps must illuminate.
F. If the red indicator light does not illuminate or glows dimly, check the trailer brake magnets and
trailer brake circuit (including the tow vehicle/trailer connector) for a short to ground.
G. If the trailer stop lamps do not illuminate, check and repair trailer wires, bulbs, bulb ground
connections, and the tow vehicle/trailer connector.
H. Also check the red stop light wire connection of the brake controller for connections to the non-
powered stop lamp wire of the vehicle stop lamp switch.
