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..

Not sure. Tried testing a 12v wire, had to go back to tried and true tester with pigtail & clamp, which gave me the result I was looking for. Maybe not doing something right, or I'm not enough negative polarity to give it a ground source. Inexpensive enough, I'll try again

The best suggestions that I can give you is to test it out on some different wiring. Once I know whether or not its working on some different wiring, then I can better assist you.



by:

I lost a $75 Snap-On circuit tester and bought this one to replace it. Not only is this tester easier to use but the cost is less than a third of the Snap-On version.



by:

Still using it on occasion. Have to watch the batteries.

  • How to Determine What Wire Functions are on 2007 Ford F-250
    If you take a look at the accompanying diagram, which is from our linked help article on wiring, you can see the common wire colors used by manufacturers. I want to stress that the only way to know for certain the functions of each wire on the 7-way of your 2007 Ford F-250 is to use a circuit tester such as # PTW2979. There are a couple reasons for this, notably because there is not a standard color for 7-ways in regards to function, and also because wiring may have been changed out in...

  • Troubleshooting Running Lights on Trailer Not Working
    There are a number of troubleshooting steps you can take in order to determine the specific problem, but if these were working before it likely isn't a fuse or relay, it is almost certainly the wiring on your trailer or tow vehicle. To start you will need to use a circuit tester such as # PTW2979 to test the connector on your tow vehicle after disconnecting it from your trailer. Check the wiring going into your harness from your tail lights to see if those wires are carrying the correct...

  • Troubleshooting Trailer Turn and Brake Lights Not Working as They Should
    I do have ideas about the issue and it sounds like you do not have a good ground, which is what causes the majority of trailer light problems. What you need to do is make sure your grounds are attached to bare metal surfaces and free of any paint, dirt or corrosion. Another thing to take a look at is both your vehicle and trailer connectors; check them for corrosion which can be green or white in color. A build-up of corrosion can interfere with the signals getting through the connectors...

  • Can Brakes be Added to a Trailer That Doesnt Have Any
    It is possible to add brakes to a trailer that currently doesn't have any. The place where you need to start is with the brake mounting flange. If your trailer axle(s) currently has brake mounting flanges then just let me know what the weight capacity is for your axle and I can let you know what parts you need. Otherwise you will need to have some welded to your axle. We do have options for new axles that have electric brakes already installed if you'd rather swap out your entire axle (see...

  • Locating Brake Wire on Horse Trailer to Resolve Brakes Locking Up
    The brake wire on a trailer is typically blue but this can certainly vary as trailer manufacturers tend to change up the colors they use at the factory and a previous owner may have also re-wired it using different color wiring. This is why it is always best to either try and trace the wiring back to its connection or test them by applying 12V power to the wire when trying to determine its function. The brake controller output pin on a trailer's 7-Way should be at the 5 o'clock position...

    There are a number of troubleshooting issues you will need to take a look at if the brake lights on your trailer are not working. 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...

  • Troubleshooting Brake Controller Not Working
    I'm not familiar with the Pod brake controller but I can give you some general brake controller troubleshooting steps to go over. You will need to 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 circuit tester # 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...

  • Brake Controller Troubleshooting
    I am not sure which of our aftermarket brake controllers you purchased or exactly what you mean by the "manual control works but it does not work with the brakes," though I can help you with some troubleshooting steps to go over on your 2019 Chevy Silverado 2500. If you were referring to the trailer brakes working with the manual override but not your truck's brakes, what you can do is check for a blown CHMSL fuse and the CHMSL bulb as well. If you have done that, you will need to find...

  • How To Wire 5-Pole Flat To Kia Telluride For Trailer With Reverse Lockout
    To adapt the 4-pin flat connector like part # 118784 on your 2020 Kia Telluride you will need to use the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter part # 20036 which changes the 4-pole flat to a 5-pole flat on the Kia. The 5-pole flat are commonly used on boat trailers for the reverse lockout on the surge brake actuator. Since the blue wire powers the reverse lockout on the trailer the blue wire gets spliced into the reverse light wire behind the tail lights on the Kia. To find...

  • 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 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 knob. To install the Curt Spectrum...

  • Troubleshooting Trailer Brake Lights and Running Lights not Working
    Since you hooked up your trailer to your Explorer and the lights all worked but the trailer's brake and running lights are not working when hooked up to your 2014 Ram 1500 we can pinpoint the issue to your Ram's wiring. Start by using a circuit tester such as # PTW2979 to test the connector on your Ram after disconnecting it from your trailer. Check the wiring going into your harness from your tail lights to see if those wires are carrying the correct signals, if not then check that wiring...

  • Troubleshooting Trailer Brake Controller That Only Works With Manual Override
    It sounds to me like you have misidentified the stop light switch and wired the brake controller incorrectly, which explains why your brake controller only works with the manual override. The stop light switch won't be hot all the time, only when the pedal is depressed, so you will need to use a circuit tester such as # PTW2979 and find the wire that is only hot when the brake pedal is depressed; this will be your stop light switch. I have linked help articles on installing brake controllers...

  • Weak Trailer Brakes When Using The OEM Brake Controller
    If you connected a separate 12v source to the trailer and the brakes seem to work fine then it could be your factory brake controller itself. There has been issues with factory brake controllers on the Ram trucks. In order to connect an aftermarket brake controller to the Ram truck the factory brake controller has to be disabled by an authorized dealer or the two will interfere with each other. It sound as if the power wire coming from the factory brake controller has a weak spot or a short....

  • 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...

  • How to Tell if 2019 Toyota Highlander Has Factory Tow Package
    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 might have the tow package (or if it's even available elsewhere). If you don't have a V6 then you can try contacting your local dealer with your VIN to see if they can help you out with that or you can use a circuit tester like part # PTW2979 and test the...

  • Troubleshooting Right Blinker on Vehicle Causing Left Blinker on Trailer to Function
    There are a few possible reasons as to why the right turn signal on your tow vehicle is causing the left tail light on your trailer to blink but most likely there's a simple crossing of wires on the trailer or a short on the vehicle. What I first recommend doing is taking a circuit tester like # PTW2979 to test the pins on your vehicle side connector. Test the pin for the right turn/brake signal on the connector while you have that function activated on the vehicle. If you don't get power...

  • Installing Curt Powered Light Converter Kit C56190KIT on 2013 Audi A5
    When installing a universal trailer wiring kit like the Curt Powered Light Converter Kit # C56190KIT the best thing you can do is simply test the wires behind the tail lights to ensure the correct functions when splicing into them with the harness. I wasn't able to track down specific wire colors for your Audi, but even when a diagram is found it's still always best to test them, as vehicle manufacturers tend to switch up wire colors without notice at the factory. You will need to use...

  • 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 out...

  • Troubleshooting Intermittent LED Tail Lights
    The problem you are experiencing with intermittent LED tail light functionality is very likely because you have a poor ground, which can cause all sorts of funky problems. What you should do is make absolutely sure your grounds are attached to bare metal surfaces and free of any paint, dirt or corrosion. If you have a good ground you will want to move on to your connectors and check them for corrosion, which can be green or white in color. A build-up of corrosion can interfere with the...

  • Replacement 7-Way Trailer Connector for a 2003 Chevy Silverado
    The 7-Way trailer connector on the back of your 2003 Chevy Silverado should have a round plug behind it that plugs into another harness that continues up to the front of the truck. What you can do is use # C55774 which comes with a new mounting bracket and has both a 7-Way blade style connector and a 4-Way flat. Or you could use # PK11916 that you referenced if you just want the 7-Way. Both options are assuming none of the wiring was damaged. You can use a circuit tester like # PTW2979...

Because of this and the picture you sent in it looks like someone may have modified the wiring on your Ram. I can give you some pointers on how to install a 7-Way but unfortunately I don't know what color wire is for what function in your picture.

    I can help you figure out exactly how to determine how to connect your wires, but wire colors are not an indicator of function on trailer wiring (or any wiring) because there is no universal color code, though that would be great.
