Troubleshooting a Tekonsha Primus Brake Controller # TK90160 That has Power But Does not Work

Question

Question:

The first time I used my system I set it on 8 and that was good. But the last time I used it I could not get it to set so I was wondering is there anything that could have been pushed to stop it from working right. It does have power to it

Are there any error codes popping up with your controller now that it seems to no longer be working? If not, it almost sounds like your trailer connector is not making good contact anymore and its not able to send brake voltage to your trailer.

Unless somehow the power knob got turned all the way down it should function just like it did as long as everything is hooked up correctly.

I also attached an FAQ article and video on troubleshooting brake controllers that you might find informative also.

Most likely you have either corrosion on the brake output pins of your trailer wiring or the pin was bent which is preventing the contact from being made. I attached a help article on brake controller troubleshooting for you to check out as well.

Answer 9

Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make…

Answer 10

There are a number of factors involved when converting a semi 7-way to an RV 7-way. Semis generally use a 7-pin round pin socket, similar to #PK11720. And RV style 7-way uses blades, like #PK12706. We do not offer any pre-made adapters to make this…

If you have a vehicle specific wiring harness for a brake controller then that would indicate that you have a factory tow package and subsequently would already have a 7-way at the back of your vehicle. The universal 7-way connector #ETBC7 is meant…
