Performance Tool Cordless Circuit Tester Review Video

There are a few things that can cause the brakes to lock up on a trailer. First, disconnect the trailer from the vehicle. Then use a circuit tester like #PTW2979 if needed to test the connector on the vehicle. Have someone sit in the truck and run…

Since your brakes have been adjusted properly, that definitely rules out one issue. The overgreasing of the hubs and failing grease seal wouldn't have any impact on the braking unless somehow the grease got inside the drum, but you still want to…

It sounds like your problem may be that you are installing too much grease into the hubs and that is why they are blowing out. If you are pumping your grease into your hub with a grease gun you should note that you should only continue to add grease…

There are many things that can affect the voltage on the brake output wire from your brake controller to your trailer brakes such as the power setting on your brake controller, how you are testing the wire and if you are testing it with the brakes or…

The best way to add a 5-Way connector to your 2016 Jeep Wrangler is by using the Tow Ready Adapter #20036. This plugs into an existing 4-Way on your vehicle, like the T-One #118416, for the basic trailer light functions, and then you splice in the…

For some reason Toyota isn't very forthcoming with how to figure out if you have the tow package or not. From my understanding all of the V6 models of the 2019 Toyota Highlander have the tow package but it isn't specified as to what else…

You can hard-wire in a brake controller, and it seems that there are not a lot of the Sprinter 3500 models that are pre-wired, at least from what I've seen in my research. I have not seen any reports that this isn't possible, and we even have…

Not necessarily. If your 2015 Lexus RX 350 came with the tow package then you just need the T-One #118252, but if it doesn't have the tow package then you need the T-One #118255 with the converter. The tow battery fuse slot would only be used if…

Typically, if your trailer is exposed to the elements, the breakaway battery should last at least a full season. There are many variables that can affect a batteries life expectancy. The Engager trailer breakaway #20099 includes a built in battery…

When this happens it means the stoplight circuit is shorting out to the brake output circuit. I bet if you turned on your blinkers one side would cause the brakes to intermittently lock up too. What you need to do is go over the wiring of the trailer…

If your breakaway battery is dead, your brakes should operate while connected to your vehicle's 7-way trailer connector. If your brakes are not operating, then it sounds like you might have a short in the brake wiring of the trailer. Battery…

I have a suspicion about what might be causing the problem you mention. Do your trucks have 6-way trailer connectors? Or, do the trucks have 7-way connectors, but you are using a 6-way to 7-way adapters because the trailers use 6-way connectors?…
