Cordless Circuit Tester: The Breakdown Video

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…

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…

A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…

It is very likely the fuse if you are not getting the 12 volt auxiliary power at the 7-way of your 2020 Ram 3500, so you'll want to check your owner's manual to see where that fuse is located or your local Ram dealer can tell you. If it's…

Trailer wiring generally uses 16 gauge wire, part #16-1-1. However, with a long trailer like yours you may want to go with a larger like 14 gauge #DW07550-1 or even 12 gauge #12-1-1. Each size is sold by the foot. You will need to have the lights at…

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 a number of potential issues that could be causing your running lights not to work, but you will have to troubleshoot the problem with some detail. The first thing to do is take a look at your vehicle's owner's manual to locate any…

Thanks for the pictures! The plate you are needing to get behind is for your gooseneck ball in bed hitch. You will have to remove that to reach the bolt. This will allow you to install the Firestone item #F2703 air bags on your 2012 Ford F-250. I…

Installing the #F2703 on your 2012 F-250 will require moving the block in your picture. However, I'm not sure if it can be moved to the top of the jounce stop since we don't have any information on it and neither did Firestone. I recommend…
