Video Transcript for Pollak 7 Way to RV Socket Circuit Tester Review

Today we're going to show you the Pollak 7-way RV socket LED tester. Part number PK12741. This tester is designed to work with seven pole connectors, works on your RV or in this case we have a truck with a seven pole built in from the factory. It has LED indicators for all the functions. We'll go ahead and cover the markings. LT for left turn, TM for marker lights or trailer marker lights, RT for right turn, [email protected] volt for our constant supply out for our trailer, BK for brake controller output if your truck or RV has it, and BU for our back-up light. Now we have six functions here, number seven would actually be our ground.

We'll take a look a the top here, you can see has all brass contacts just like any other seven pole connector. So this is very handy to keep with your trailer. If you happen to use your trailer on different vehicles, you can verify if the truck that's pulling it is working correctly or not. Let's go ahead and try it out on our truck. It plugs in just like any other seven pole connector. Line up this key with the groove.

On the connector just push it in firmly and you can let the lid rest, but I'm going to hold it up and you can see right off the bat it's showing us that we have a constant 12 volt supply from the truck. Next we'll go ahead and go through the functions and we'll make sure everything works. Okay, first off we'll go ahead and take a look at the left turn signal. Okay, that works. Now we'll turn on the running lights or the headlights. Okay, we have a good circuit there.

Let's turn that off and now we'll try the right turn signal. Okay, good function there. Of course we have our 12 volt power supply. Now our vehicle does not have a brake controller, but it would light up the same way as the other two. We've put the vehicle in reverse.

Okay, we see we got reverse light. And also if we had the brake light we'd have the brake pedal pushed on. WE can also see how the right turn and left turn come on at the same time. All right, and with that that'll finish it for the Pollak Seven-Way RV Socket LED circuit tester, part number PK12741.

There have been several times this tool has helped isolate problems with trailer wiring by insuong tow connector AOK. 5th wheel, horse trailer, flatbed, and touhauler all had either a bad connector, a bad wire, corrosion issue, difficult to isolate but easy to repair. Saved a lot of time.

Not much to say about a trailer plug tester other than it works just fine and is as advertised. Shipping was prompt and I was able to solve my neighbors wiring problem quickly without a hassle. If I ever need any trailer related parts or ?? You people will be the first that I will contact. Thanks

I bought the 7-way LED circuit tester. I bought a used Class A motor home and have had problems with the 7-way plug on the motor home This will help me resolve the last issue. A few weeks ago I had also purchased the 4-way flat LED tester and now have both in my tool box. Thanks

works well. worth the price. you have to make sure you get the correct one. those 7 pins can be wired differently. email them and tell them what vehicle you have. some trailer hitches have the groove on top some on the bottom. if yours is on the bottom you will have to lay on the ground to read it, because the lights will be pointing at the ground. the lights are on the groove side.



- PK12741
by:

Arrived promptly and it worked as expected when I tested it on my tow vehicle. A previous reviewer stated that he wished there was a card that listed what each light tested. It is marked on the plug around the test lights, but the printing is the same color as the plug. That is the only reason that I gave this product 4 stars. I used a paint stick to highlight the markings so that I can read them easily without my glasses.



- PK12741
by:

The tester plugs in easily and works fine. It's hard to remember what the lights mean. It would be helpful to include a small heavy paper or plastic card that could be carried with the tester that identifies the lights.

Super helpful to have one of these testers. I suspected my trailer battery was not getting charged by the tow vehicle, and this tester confirmed the problem was my 12 volt wire is not active. Saved me time as now I know where to go next for resolution. Also easily can confirm my truck's trailer plug works without having to hitch up. Totally worth it in time saved.

Good and useful product. Only problem is that if the Pollak keyway on your vehicle is on the bottom side you can't easily see the LED lights! This would be a more useful product if the lights were visible from both sides. Suggest a design change to do that would be appropriate.



- PK12741
by:

It works great. I have used it on several vehicles. Only problem is using it on GM vehicles the light display is on the bottom side when you plug it in which makes it hard to read.

Worked well. After testing, my new RV is headed back to the dealer to fix a wiring problem with the trailer light jack.

  • Tow Package Fuse and Relay Locations for a 2005 Ford F-350
    The fuse locations and functions are listed in the owner's manual for the 2005 Ford F-350. There are a lot of documents on the Ford site for the truck so it is possible you were looking at one of the others which would not be helpful for this. The fuses related to any tow package wiring are as follows: Passenger compartment fuse panel: Location 20: 15 amp, Trailer tow Electric Brake Controller (EBC) Location 28: 10 amp, Trailer tow EBC logic Location 38: 20 amp, Trailer tow park lamps Location...

But I can tell you that. If you are looking at the face of a vehicle side 7-Way where you would connect the trailer: 1 o'clock position is 12 volt power 3 o'clock is right turn and brake lights 5 o'clock is output to trailer brakes 7 o'clock is ground 9 o'clock is left turn and brake lights 11 o'clock is...

  • Tip for Pulling Out Fuses of 2002 Ford F-350
    Sometimes fuses can be difficult to pull out as they are pretty small, fit tightly in the slot they are installed in, and typically there's just not enough room to fit your fingers between them enough to pull them out. I'd grab a set of needle nose pliers to pull out and install the fuses of your 2002 Ford F-350.

  • Does Flicker of Brake Output Circuit on Trailer Wiring Mean There's an Issue
    The flicker you are seeing on the brake output circuit of your vehicle is normal. Brake controllers will lightly pulse their output circuit to check to see if a trailer is connected due to the amperage draw of the brake magnets. So what this all tells me is that your issue is most likely on the trailer side of the equation. This can be as simple as corrosion on the pins of the trailer wiring connector or it could be damaged wire, bad brake magnets or the grounds of the assemblies having...

  • How Could Pollak 7-Way Tester part # PK12741 Test Brake Controller Circuit
    To use the Pollak 7-Way tester part # PK12741 that you have to test the brake controller of your vehicle will require a buddy to press the brake pedal of your truck to see if the voltage from the brake controller makes it to the tester and lights up the correct LED. Also have them use the override handle of it to see if that lights it up as well.

    There are a couple of ways to do this, the easiest way would be to use a plug-in tester like # PK12741. Simply plug the tester in to the 7-way trailer connector on your truck and have a helper activate each taillight function while you observe the tester. A circuit tester like part # 40376 could also be used. Turn on the running lights on the truck, ground the tester and touch the pin in the 11:00 position with the probe of the tester. If that pin doesn't show power, you likely have a...

  • Can 7-Way Circuit Tester Be Used on Upside Down Ford 7-Way
    We have 7-way testers that will work for you like the part # PK12741 but since your 7-way is upside down the display would be harder to view since you'd have to be underneath the tester. We don't have an easy solution for that unless you wanted to try and rotate the 7-way 180 degrees.

  • Troubleshooting Only Running Lights Working on Trailer
    The first thing to do is take a look at your owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order. If they are, in order to determine the specific problem you will need to purchase a circuit tester if you do not have one - the very handy Cordless Circuit Tester # PTW2979 would be my strong recommendation due to how easy it is to use - and test the connector on your vehicle after disconnecting it from your trailer. Check the wiring going...

You should have both the stop and turn combined for the left side at the 9 o'clock pin position and the stop and turn for the right side combined at the 3 o'clock position. When you have the brake on, the turn signal should still function. You can use a 7-way tester like # PK12741 to test that function as well. I've attached a video to assist. If you have the both functions for each at that location,...

    The P3 brake controller # 90195 will only send back a little bit of power when just sitting so if you use the manual override on the controller then it should light up the tester solid. Using the brake pedal to test also will not work properly because the controller will not send back power if the vehicle is not moving. There are other ways to test a brake controller. In the truck cab you will need to sever the blue wire several inches from the back of the controller. Then use a circuit...

  • Will 7-Way Trailer Connector Tester Work With 2011 Chevrolet 2500 HD Factory Brake Controller
    The TowReady 7 Way Trailer Connector Vehicle Tester you referenced, # TR20117, is not compatible with all factory brake controllers. I don't believe it is compatible with your 2011 Chevrolet 2500 HD. A similar design that is compatible is the Pollak 7-Way to RV Socket LED Circuit Tester, # PK12741. This will work with your vehicle's factory controller and will be bright enough for outside use. You may need to shield direct sunlight from interfering with your reading.

  • Troubleshooting Black Screen on Hopkins Smart Hitch Camera in 2013 Ford F-150 with OEM 7-Way
    I reached out to my contact at Hopkins and they suggested testing the center pin on your 7-way with the help from a friend who can shift the vehicle into reverse while you test. You can use a tester like the Pollak LED Tester # PK12741 which is super easy and simple to use. If no power is going to the center pin then check your fuse box as it may be missing a fuse and/or relay to activate the trailer tow backup lamp circuit. This is very common on Ford trucks like your 2013 F-150.

  • 2004 Ford F-250 Auxiliary Charge Line Fuse for 7 Way Connector
    I'll start by saying that how your trailer lights are powered depends on how the trailer is wired; in most cases the lights on your trailer are going to be powered the auxiliary battery on your trailer and not on a separate circuit. This battery is going to be charged by the 7 way connection between your truck and trailer. I would start by verifying that your 7 way connector is providing power to all of the circuits; you can use a 7 way tester like the # PK12741 to test to make sure that...

There have been issues with vehicles such as Audi, Mercedes-Benz, and Volkswagen that have issues due to the LED lights having such a low power draw.

    Circuit tester # PK12741 will likely not draw enough power to make the tow package on your 2013 Audi Q7 think a trailer is connected. This is due to the light power draw from the LED lights. What you need is adapter # C57003 for a 7-Way to 7-Way or # TR20141 for a 7-Way to a 4/5-Way. These adapters have load resistors that will simulate additional load on the system so that the vehicle won't throw the bulb out alert when a trailer is connected.

Since you said you checked out the #63 fuse, and it's all good, I recommend checking your 7-way connector/receptacle. You'll want to ensure that your connectors are free from debris and not corroded.
