1. Power Issues

      A. Unit does not power on/comes on dim/does not hold a charge

1. If the light does not appear to power on properly when you turn the switch to the “On” position, first try turning it on when it is plugged in to the charge cord.

 

     a) If the light comes on fully while plugged into the charge cord but not at all when off of it, it could be a blown fuse in the light or a battery.

        (1) To check the fuse in the light if it is a magnetic unit with end caps, open the end of the light opposite of the switch. You will find a fuse link in line of the red wire going to the battery. Check the fuse and replace if blown. (If the light is not magnetic or does not have end caps, remove a light from the face of the unit in order to access the battery and fuse link.)

 

     b) If the light comes on fully while plugged into the charge cord but only dim when off of it, the battery needs to be replaced.

 

     c) If the light does not come on fully while it is plugged in, check the fuse in the charge cord to be sure that it is intact.

          (1) If the fuse is blown, replace it with a 5-10Amp fuse and try to power the unit on again.

          (2) If the fuse is not blown, use a test light or volt meter to check the output of the charge cord.

 

     (d) If the charge cord is not putting out voltage and the fuse is good, it will need to be replaced.

 

     (e) If the charge cord is supplying voltage all the way through, move to the next step.

 

2. If the fuse in the charge cord is good, but the light will not power on fully while plugged in to the charger, see if the unit comes on when the switch is bypassed.

 

     a) To bypass the switch, take the two sets of wires that go to the contacts of it and jump them together using another piece of wire or a paperclip.

          (1) If the unit comes on fully when the switch is bypassed, the switch needs to be replaced.

          (2) If the unit does not power on when the switch is bypassed, move on to the next step.

 

3. Since the light did not come on with the unit plugged in to the charger or with the switch bypassed, the problem is either in the charging port or the battery.

 

     a) Open the unit from the right side (the side opposite of the switch) in order to remove the battery or fuse. You may need to remove the lens or lens screws on that side of the light, and possibly the magnet,

     in order to remove the battery from the unit.

          (1) If removing the battery, please disconnect at least one of the two wires in order to eliminate it from the equation.

         (2) Plug the unit in to the charge cord and try to power it on.

 

     (a) If the unit comes on bright, the battery will need to be replaced.

 

     (b) If the unit does not power on at this point, the charging port will need to be replaced.

 

 

 

2. Communication Issues

 

A. No Range

1. If the unit communicates when in close proximity to the sending unit or transmitter, but not at the rear of the load you are hauling, the electronics have likely failed and will need to be replaced under warranty. Simply call

(800) 680-4455 for service.

 

B. Turn Signals Are Backwards

1. If the turn signals appear to be responding opposite to what is activated on the truck, it is likely that the wiring in the transmitter is simply opposite from how the truck is wired.

 

     a) To fix this, simply open the transmitter by removing the set-screw at the base where it receives the pins and pull the end out.

 

     b) Switch the yellow (left turn) and green (right turn) wires and put it back together.

 

C. No Signal

1. If your light is not responding or only one side seems to be responding, there is a chance that it is merely a connection or ground issue.

 

     a) First, spread the pins on the truck to ensure that all of the pins are making good contact with the transmitter.

 

     b) If step (a) does not fix the issue, run a bench test utilizing a 12V source and run direct power to the transmitter with the light powered on.

          (1) A jump pack or simple 12V battery will provide an easy 12V source to run a power and ground wire off of.

 

          (2) Touch the ground wire to the ground pin of the transmitter and the hot wire to the other pins to get your turn signals. The brake on a 4-Pin is created by combining the two turn signals. On a 7-Pin there is a separate pin for the brake function.

 

                (a) If the light does not respond when tested in this manner, the electronics are faulty and will need to be replaced. Simply call (800) 680-4455 for service.

 

                (b) If the light responds when tested in this manner but not when plugged into the truck, there is either mismatched wiring or an insufficient ground.

 

3. Tips and Tricks

     

        (i) The instructions that came with your light should show the wiring of our transmitter and can be used as a guide while you verify the wiring on the truck.

 

        (ii) If the wiring of the truck matches the wiring shown on the instructions, verify that the ground pin of the truck is grounded directly to the chassis, which will provide the best ground.

 

        (iii) Note that a wired set of tow lights will often use the plug itself as the ground and may not be the best indicator of whether the wireless tow light will work or not. Follow all troubleshooting steps before drawing any conclusions based on a wired bar.
