Video Transcript for Brophy 4 and 5 Way Flat Circuit Tester Review

Today we're going to be taking a look at the Brophy 4 Pole and 5 Pole Flat Pass Through Circuit Tester. Part number is F5CT. As you can see our tester, this is going to be a completely one-piece unit here. We're not going to have different pieces clicked together or anything. That gives us really good dependability. Each of our connection areas here is going to have some corrosion resistant material there to helped prevent any rusting or corrosion.

Lights molded right in so we won't have to worry about those coming loose or anything. It's kind of a rubberized material, so it's going to be good and rugged and the reviews say it's really dependable, it's going to last a good long time. A nice thing about the cap, it's also been molded on so we don't have to worry about losing that or it falling off. It will always stay permanently attached for us. A pass through so we're actually able to plug our trailer in on the other side of it, if we just want to leave it in place. If we want to store it in the car, simpy remove it and plug our trailer in normally.

This is going to test out, one our ground, to make sure we've got a good ground, but also it's going to test out our tail light, left turn signal, right turn signal and also the back up signal. That's labelled as an A. That's going to be for a lot of marine applications. That's going to be if you have a 5 pole. If you only have a 4 pole, it's going to be the first four.

When you step on the brakes, you want to see the two in the middle there light up. It plugs directly in line as we said, with any any four or five pole application. This is just going to slide in just like that, and then we can either cap that off if we're just going to be running tests. If we're actually going to use it as an in line tester, so we can monitor that, we can plug our trailer in right there, nice and easy. Let's get it plugged into our vehicle here. Now I'm using the aid of a seven pole round to a five pole adapter that we sell here at etrailer. We'll start with our running lights.

Left blinker, right blinker, brakes and reverse. This is going to be a great, quick and easy way to test our wiring to make sure everything is working before we get on the road, or monitor it as we head down the road to make sure we don't have any shorts. Now as far as measurements are concerned, you can see we're going to have a lip 00:02:24. That's about an inch and three quarter. Then the total of what we're going to add to our actual plug, is going to be about two inches. If space is an issue for you, definitely want to check and make sure that you've got that extra two inches that you need, but then you can simply plug in and head down the road. That will complete our look at the the Brophy Four Pole and Five Pole Flat Circuit Tester, part number F5CT.

Pros - Well made product that works as designed. - Dual connector design allows user to leave circuit tester installed between vehicle and trailer for continuous circuit monitoring while the trailer is hooked up. Cons - Lacks a means for securing the circuit tester to the vehicle connector or trailer connector. A pair of 'fore - aft' eyelets on both sides of the circuit tester would allow user to secure the various connectors to each other while in use. - (minor) Why no dust cap for the vehicle-side connector? Both connectors have female receptacles, so capping both would be best. Overall, a great product with an innovative design. I would have given it 5 stars if it weren't such a pain to secure the connectors when used inline between my truck and trailer. 452235

Ask the Experts about this Brophy Wiring

  • Recommended 4-Way Trailer Wiring Connection For 2005 Toyota Tacoma
    The blinkers and brakes should be on the same wire. 4-way systems put the right blinker and stop on one wire and the left blinker and stop on another wire. Then the remaining two wires are running lights and ground. I've attached an article to assist. You can test your vehicle 4 way using the Brophy 4- and 5- Way Flat Circuit Tester # F5CT to ensure proper function on the vehicle side. My recommendation is to use the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer...

  • No Function on any Right Side Lights on Trailer Behind 2010 Subaru Forester
    I have found the best way to find a bug in an electrical system is by process of elimination. Eliminating possible sources will eventually lead to the right spot. First thing I would do, is check the 4-Way connector on your Subaru Forester. Using a circuit tester like part # 40376 or a 4-Way tester like part # F5CT or part # I26. The white wire is ground, the yellow wire is left turn and brake, the green wire is right turn and brake, and the brown wire is tail lights. Chances are, the...
