Troubleshooting Dimly Lit Tail Light Circuits on a Tekonsha 7-Way Emulator with 2002 Toyota Tundra


Installed a 7-pin plus the 4 way to a 2002 Tundra. After plugging in the # 6562, the LT- TL - RT are dimly lit, but when I check each light the lights become much brighter. Is there some feed-back voltage causing this dimly lit condition or is this normal? I have had several issues with this new trailer, up to and including the backing plate welds on one side broke and tore out the brake wiring. The manufacture replaced the axle. I am still have electric brake problems and was wondering if I may have a feed-back issue. The trailer is very sturdy, but I am not impressed with its wiring.


Helpful Expert Reply:

If the Tekonsha 7-Way Trailer Emulator # 6562 that you referenced is picking up a small amount of voltage then that issue is coming from your 2002 Toyota Tundra and not the trailer. Some vehicles will have a small amount of voltage available on certain tail light circuits. If the tail lights of your trailer seem to work when connected to your vehicle then I would not let this bother you.

If you are still concerned you could take a multimeter like our part # PT89ZR and test to see how much voltage is present at those circuits.

I am sorry to hear you are having so many issues with your trailer. It sounds like the manufacturer should stand by their work and take care of your problems.

I attached an FAQ article on troubleshooting brake controller installs for you to check.
