Video Transcript for Performance Tool Cordless Circuit Tester Review

Today we'll be taking a look at the Performance Tools Cordless Circuit Tester, part number PTW2979. Now this is going to be your Performance Tool Circuit Tester. It's going to be a handy little thing that's only about 6 inches long. It detects voltage from 3 volts all the way up to 28 volts. The nice thing about this is it's going to be cordless. It's going to use you as the ground so you're not going to need a wire or a clip with it.

It's going to be safe to use on ECMs, sensors, and transducers as well. It comes with 2 end type long term, long life batteries. Now here we'll go ahead and test it out. It does come with your probe as well, so if you like to just press that on to your wires and then probe your wires you can. If you have a four-pole like we do here, you can just remove that cover, hold it on the chrome or shiny part here. Then you're just going to touch the ground.

This is going to use you as a ground, so if we don't touch the ground, we're not going to get anything out of it. If we touch the ground with our finger with our freehand, you'll hear the audible beep as well as see the light flash. Now, if we let off that ground . So you'll know right away if you have a bad ground. That will do it for our review of the Performance Tools Cordless Circuit Tester, part number PTW2979..

  • Troubleshooting Hopkins 4-Way Flat Trailer Wiring Kit on a 2015 Jeep Cherokee
  • I do have a way you can test to see what it going on with your Hopkins # HM11142464 unit. If you are getting constant power on all of the lighting function pins then what you want to do is take a circuit tester like part # PTW2979 and test the wires coming from the connectors that tee in behind the taillights on your 2015 Jeep Cherokee. If those wires don't have constant power going in but they do coming out then the power module is messed up internally and you need to replace your wiring. Since...

  • Finding the Stop Light Switch Wire on a 2014 Volvo S60
  • Typically the location of the stop light switch is up and behind the brake pedal but you would need to use a circuit tester like part # PTW2979 to verify which one it is. The wire you are looking for will show power only when the brake pedal is pressed. If you check out the installation video (23:40 mark) that I attached you can see this testing being done on a 2012 Volvo XC90. If you don't already have a brake controller then I recommend the Tekonsha Prodigy P3 # 90195. This is...

  • Troubleshooting Tekonsha PowerTrac Brake Controller on a 2018 Toyota Tacoma
  • To determine if your Tekonsha PowerTrac # 39523 is bad or not all you need to do is test the blue wire coming from the controller with a circuit tester like part # PTW2979. Put the power to the highest setting and then use the manual override to send power along the blue wire to your trailer brakes. If the blue wire on the PowerTrac isn't sending power but it is receiving power on the black wire then the controller is bad and you need to replace it. The PowerTrac and the Voyager # 39510...

  • 5-Pole Round Connector for Trailer to Match Connector on 1989 Electra Glide Harley Davidson
  • For the 5-Pole round connector on your 1989 Electra Glide Harley Davidson, like part # PK11502, we have the Pollak 5-Pole, Round Pin Trailer Wiring Connector # PK11501. All you have to do is cut off the 5-Way flat connector on your trailer and then verify which pins carry which functions by using a circuit tester like part # PTW2979 so you can wire your trailer connector up accordingly! You may need a converter like part # RM-732 which takes individual stop and turn signals (like what...

  • Can Trailer Brake Controller be Used on Harley Davidson Motorcycle Pulling Small Trailer
  • The Curt Spectrum Trailer Brake Controller # C51170 can be absolutely be used with your Harley pulling a small trailer for your pups (and in the process making your wife happy). Normally with a motorcycle you want to use a time-delayed controller like the Curt Discovery # C51120 but since the Spectrum's main unit can be mounted at any angle, this is one of the proportional controllers that can be used so long as you can find a good mounting point for both the main unit and the control...

  • Recommended 7-Way Trailer Wiring Harness for 2018 Dodge Durango Without Factory Tow Package
  • The 7-way wiring harness I recommend for your 2018 Dodge Durango is the Tekonsha 7-Way Trailer Connector # TK22113 because of its relatively simple installation and the strong reputation its manufacturer, Tekonsha, has for creating quality wiring products. Installing this wiring harness on your '18 Durango will only require you plug it into connection points behind your taillights and run the body harness to your battery. I have added a link to the instruction manual for you to check...

  • Troubleshooting Interior Lights Not Working for Enclosed Trailer
  • The interior lights of your enclosed trailer are likely connected to the 12V (Auxiliary) power pin on the 7-Way of your trailer. You can verify this by applying 12V power from a separate battery to this pin and seeing if that supplies power to your lights (see attached picture). If your 2007 Chevy TrailBlazer doesn't have power on the corresponding pin (see attached photo) then that would explain why your interior lights aren't working. I took a look at the online owner's manual for...

  • Troubleshooting OEM Brake Controller on a 2011 Ram 3500
  • Yes, there are a few things you can look at to troubleshoot what is going on. First off if your brake controller is proportional like the Prodigy P3 # 90195 and you are testing your brakes while sitting still then that is the problem. Proportional brake controllers use inertia sensing to help determine how much power to send back to the brakes. If you are sitting still then the controller senses this and won't send very much power back at all. If this is not the case or you get poor...

  • Does 12V Power Need to be Run for Installing the Curt Echo Brake Controller on a 2013 Ford F-150
  • If you have a 2013 Ford F-150 then you should be getting constant 12V power on the pin in the 5 o'clock position. If the fuse in position 21 in your power distribution box (under your hood) is working properly and you just don't have that 12V power (you can use a circuit tester like part # PTW2979 to test) then you will either need to take your F-150 in to the shop or run 10 Gauge Wire # 10-1-1 from your 7-Way to your battery with a 40 amp circuit breaker like part # 9510 in-line. There...

  • Troubleshooting Curt T-Connector # 56042 on a 2017 Toyota Highlander
  • The first thing that you want to do is troubleshoot the Curt T-Connector 4-Way # 56042 itself. You can do this with a circuit tester like part # PTW2979. If you are getting signals then that means you likely have a short or damaged wiring on your trailer. If you don't get signals then you either need some fuses or relays on your 2017 Toyota Highlander. There could be wiring damage on your Highlander but I doubt it since the vehicle is so new. If the problem is on your trailer side check...

  • How to Determine Wire Functions to Wire 7-Way
  • To determine how to wire any connector you will need to determine the function of each wire with a circuit tester as there is no universal color code. I recommend the very handy Cordless Circuit Tester # PTW2979 due to how easy it is to use. Once you find their functions you can match them to your 7-way, and the accompanying diagram shows the connections for the different style of 7-ways. You should also consider going to a 6-round plug just for ease of use. I have added a link...

  • Do Trailer Lights Wire by Color
  • To wire your trailer you need to go by function instead of wire color because there is not universal wiring. So you will need to use a circuit tester such as such as # PTW2979 to find the function of your wiring as someone runs . Once you find the functions of each wire you can connect your 7-Pole, RV-Style Trailer Socket - Vehicle End # PK12703. I have added a link to a help article on wiring which I also recommend checking out.

  • Parts Needed to Tow a Trailer with Brakes Using a 2015 Nissan Pathfinder with Tow Package
  • If you have a fully functioning 7-Way already installed on your 2015 Nissan Pathfinder with the tow package then all you need is a brake controller and an adapter. You can verify that your 7-Way is fully functional by using a circuit tester # PTW2979 to test the functions like you see in the attached picture. I recommend the Tekonsha Prodigy P3 # 90195. This is a proportional brake controller that will apply the brakes on your trailer at the same time and with the same intensity as the...

I am attaching some pictures to demonstrate where each function is connected to for both...

  • Does 4-Flat to 5-Flat Adapter Require Splicing
  • Each of the vehicle-side 4-Pole to 5-Pole Trailer Wiring Adapters such as the Tow Ready # 20036 will require you to spice the blue wire of the adapter into the reverse light wire on your 2018 Toyota Highlander. It is not difficult to accomplish because this kit does come with a quick splice connector and I have also linked a video for you which shows this adapter being installed on a Highlander. You will need a circuit tester like # PTW2979 to find the reverse light signal on your Highlander. The...

  • Troubleshooting Electric Brakes Not Working
  • Although I'm not quite sure what you are referencing when you say your ground is not working there is a way you can find out if the issue is on the brake controller, truck, or trailer. To test the brake controller, sever the blue wire a couple inches from the back of your controller. Then use a circuit tester such as # PTW2979 to test the end of the blue wire coming out of the controller. It should only have power when you apply the manual override; if it shows power at idle then there...

  • The installation of a 4-flat connector such as the T-One Vehicle Wiring Harness # 118496 in your 1995 Toyota T100 is a very simple and straightforward process; it only requires plugging in the T-connectors at the taillight wiring harness. I was unable to locate what harness you ordered from us so I'm not certain what exact harness you used but the process should not be any different (see linked installation video which shows how this harness installs). If you only cut off the connector...

  • Troubleshooting No Power to Trailer Connector on 2016 Ram 3500

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 because one of these being blown is normally the most likely culprit. Should your fuses be in working order to determine the specific problem you will need to purchase a circuit tester if you do...

  • Troubleshooting Tekonsha Voyager Brake Controller

You mentioned your brakes work on your other truck with this trailer so it is likely the Voyager or the wiring on your 1988 K1500 causing the issue. To test the brake controller, sever the blue wire a couple inches from the back of your controller. Then...

  • Troubleshooting No Trailer Lights Working with 2011 Ford F-350
  • If you aren't getting any trailer lights at all I first recommend testing the connector itself on your F-350 with a circuit tester like # PTW2979. Test the pins while you have a buddy run through the lighting functions in the cab. If you don't get power at the connector then you at least know the problem is on the truck. If this is the case I first recommend inspecting the connector for any debris or corrosion around the pins that needs to be cleaned out. Check the wiring immediately...

  • How to Determine Wire Color Functions for 7-Way Connector on a 1997 Ford F-350
  • Attached is a picture of the typical wiring colors for the wiring on a vehicle-side 7-Way connector. This may differ from your 1997 Ford F-350 though for a few reasons. The first is that vehicle manufacturers don't always follow this wiring configuration so it is very likely the OEM wiring is different. The other reason is that since your vehicle is older it is very possible that someone else has done surgery on the OEM wiring and they could have used whatever color wiring they had...
