Video Transcript for Performance Tool Hook Probe Circuit Tester Review

Hi there, do-it-yourselfers. Today, we're gonna be taking a look and covering some of the features of Performance Tool's, hook probe circuit tester. A test light's a great object for verifying whether you've got power and ground at a specific location. It's also really useful if you're setting up lights on your vehicle for trailer lighting, so you can test your circuits and get those installed. So real quick, we're just going to show you here, how it works, one end needs to have ground, and the other end needs to have power in order to light the light. So we're gonna take the clip end here, we're gonna put this on the negative side of our battery for brown.

And then if we press in on the plastic sleeve here, that'll expose the probe at the end. We're just gonna touch this to the positive side. You can see there that it lights up our test light. This will also work if you we're to hook it up backwards. So if he's got the clip on power and you we're to use your probe and touch any ground point, it should also light up.

So you can see your ground on the battery or ground over here on anywhere on the vehicle frame or anything like that. Lets see if there's a bolt right down here. Look at that there, we got the power, it's lighting up our test light because that's ground and we've got power coming from the clip side. Our customers typically use these to check their circuits, especially if they're either setting up a four-pole connector on their vehicle, or if they've recently just taken their vehicle and they hooked it up to their trailer and they found, "oh no, the lights aren't working on my trailer." Well now you've got to figure out why the lights don't work and the test light can be a great tool to help you determine that. One of the first things that I would do if I had an issue with my trailer not working properly is I wanna verify is the issue with my trailer, or is it with my vehicle And I'd start here on the vehicle and check this out.

So we've got our four pole tester here which gives us all of our necessary lighting signals, in order to get these to operate without an assistant, we can go ahead and turn on our hazard lights that will operate both the left and the right turn signal. And we can go ahead and turn on our tail lights for our last circuit, the fourth circuit there is your ground and that's the exposed lug there. We went ahead and used the clip to clip it onto the ground side. So now we've got those lights operating. We should get some signals from the first one here next to it's going to be our tail lights.

We should have a constant voltage it should light up our light and look at that, there we go. So we know our taillight signal is working properly on the vehicle. Next is the yellow circuit, which is our left turn signal. And we can see it's flashing, so we know that our left turn signal is working properly. And lastly is the green circuit that's our right turn signal and it's working as well. So we plugged this vehicle into a trailer and the trailer doesn't function, there's some issues on our trailer side, maybe there's a ground missing to the light that's not functioning or maybe there's just an open and the power circuit go into it. But we know, at this point that our vehicle is working properly and we can continue the diagnosis over on that side. And while we we're showing it off on a four-pole here, it's also great for testing out your six and seven-pole connectors as well. You just need to make sure you've got a way to activate the particular circuits to make sure they're working. For example, like your seven way, your auxiliary circuit probably is going to have 12 volts on it at all times, but some of those require the vehicle to be started in order to get that 12 volt output. Likewise, your brake output circuit for your trailer brakes aren't gonna activate unless you've got an assistant inside either pressing the brakes or activating the manual slider. But if you've got somebody to help you out, you can check all those circuits with this as well. So now, since we know that our problem is not with our vehicle, you can go ahead and plug your vehicle out to your trailer, or you could use a test box. We've gone ahead and plugged up and got our tail lights turned on and our light here is not functioning. So let's check our circuits and see if we can figure out the issue. I've gone ahead and clipped the wire there where the ground wire was attached. We could potentially just have an issue with our ground, but we're gonna go ahead and use that and see if we can get a reading here. So here's our two circuits coming from the front, you got a green wire there and a brown one. Brown is your typical color for your taillight circuit. So I'm just gonna push this away from the probe there. Gonna slide it over and then I'm now letting it return. And we're gonna stab into the wire. And with our taillights on, if we've got a good ground here at the back, we should get a reading. Now, even though brown is the most common color, that's not always the case though sometimes it can be another color. So we have nothing here. So we're just gonna go ahead and probe the other wire. 'Cause even though brown is the most common, it doesn't necessarily mean that the manufacturer, followed that particular color coding. So now we are on the other one, we're gonna probe into that one, and we've got nothing on that one either. So that probably leads us to believe that we either have a short from, other than just to believe that we have an open in our circuit here preventing current from getting to the back or that we've potentially got a bad ground here at the back. We're gonna take that clip off the ground circuit, where we had it, where it was getting ground from before. And we're gonna move it to a new spot here on the trailer. 'Cause we should have good ground just about anywhere on the frame, as long as the paint's not too thick. And look at that, we moved it over to the other stud there. We kinda rocked it around to clear up some of the rust on it and we've got power which we now know that from the vehicle all the way back to our circuit here is good. So the only issues that's potentially left is our ground or the bulbs could be burnt out. But since we moved our circuit from where the ground wire is here over to a different spot we got our lights light up. I suspect our issue is more than likely with our ground here. So we're just gonna go ahead and tighten the circuit up, kinda clean up that rust there and see if we can't get this light to come back on. And that's all it took, I just took that bolt loose. I knocked some of the rust off with a wire brush, re-installed it and now our light's functioning. So you can see our test light was able to help us determine that the issue was on the trailer side and also figure out where that issue was. And that completes our look at Performance Tool's, hook probe circuit tester..

I bought this prob/circuit tester in order to make some minor electrical repairs to our Scamp 13. I carry it along on all our trips. It has been tremendously helpful isolating shorts that result from vibration and wear and tear. Furthermore, the tutorial videos here on etrailer have been equally helpful.

Easy to use and definitely helpful when looking for a specific wire.



by:

I had a tester like this years ago and I broke the end off.
I really liked the tester as you can hook it over a wire and probe it to see
if you have voltage.
Been looking for one for a long time.
You can find cheap junk ones but this one is just like the good one I had years ago.
Glad I found it and is is very well built.
Should last me a long time.
Was shipped fast also.
Will try and not break this one.
Thanks e trailer.

  • No Numbers Display on Prodigy Brake Controller when Setting Up the Controller
    It sounds like there could be a problem with the brake controller or the connections going to it. The first thing you will want to check is to make sure the controller is getting power. Use a circuit tester such as # PTW2993 to test the black wire going into the controller. If it does not have 12-volt power, then that would be the problem. There are different things that can occur that would make this happen. If you happen to have a Chevy/GMC truck or SUV then it is likely that you will...

  • Trailer Lights Work on One Trailer but Not on Three Other Trailers Towed by 1998 Toyota Tacoma
    It sounds like a problem with the ground or wiring on the trailers, but it would be wise to check all of the components in your wiring system. You can test the trailer connectors on the 1998 Toyota Tacoma and the trailers with a circuit tester like part # PTW2993. I am including a link to a FAQ page on trailer wiring that will show you the functions of each pin on your connector, depending on if it is either a 4-Way, 5-Way, 6-Way, or 7-Way. This will help you determine if there is a problem...

  • Prodigy Brake Controller Flashes SH After Moving it from One Car to Another
    The circuit breaker would reset so the power would be interrupted, and you wouldn't see a display during that time, so I don't think it is the circuit breaker. The white ground wire, if hardwiring in the controller, should go to the negative battery terminal. It needs a substantial ground and that is the best place to get it. The SH is indicating a short circuit It could be the red wire. On a brake switch there can be more than 1 wire that shows power with the brake pedal. If the wire...

  • Troubleshooting Draw-Tite Activator ll Brake Controller On 2002 GMC Sierra
    Since you said the trailer lights work great on other vehicles that helps narrow down the probable cause of the problems you are having. There is some testing you can do. In the truck cab you will need to sever the blue wire several inches from the back of the controller. Then use a circuit tester like part # PTW2993 to test the end of the blue wire coming out of the controller. It should only have power when you apply the manual override or brake pedal. If it shows power at idle, then...

  • Electric Trailer Brakes Make Noise But Will Not Engage
    The first thing you will want to check is the output voltage on the brake controller. If it is set too low, it will not send enough power back to engage the trailer brakes. For testing purposes, it is easiest to set it to full power. Using a meter or circuit tester like # PTW2993 make sure that power is getting back to the trailer connector, which it does sound like it is. Then with the trailer connected make sure power is getting to the brake magnets which again it sounds like it is. That...

  • Troubleshooting Left Stop/Turn Light Not Functioning On Trailer
    Sounds like you are trying to figure out why the left brake light on your trailer isn't functioning but the rest of the trailer lighting seems to be working. Typically this problem is due to a bad ground on the light assembly. The light grounds should be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding tongue, any of these things can interrupt...

  • Troubleshooting Electric Brakes Not Working on Dual Axle Box Trailer
    In order to determine why the brakes aren't working on your dual axle trailer, I recommend first cutting the blue wire 5-6 inches behind the controller and use a circuit tester like part # PTW2993, to verify that power is present. Power should be present when the manual override control is used. If no power is present, the brake controller may be malfunctioning and require replacement. The next step would be to test the 7-way on your tow vehicle. Using a circuit tester, verify that power...

  • Trailer Right Turn Signal Problems with a 2006 Chevy Silverado
    First thing I would do is disconnect the trailer from your 2006 Chevy Silverado so you can check the vehicle side connector with a circuit tester like # PTW2993. Test the right turn/brake signal. You should experience the same issue here since it sounds like you've isolated the issue to the truck and not the trailer. Make sure the connector is clean and free of any dirt or corrosion. Using a wire brush should suffice. If the wires behind the connector are frayed, cut them off at the damaged...

  • Can Trailer Wiring Harness for 2011 Kia Sorento be Powered through Wiring at Back of Vehicle
    First you will want to confirm that your 2011 Kia Sorento does in fact have the factory tow package. The presence of the wiring does not necessarily mean that the vehicle has the tow package as the wiring might not be active. The easiest way to do this without doing any work is to have a Kia dealer run the VIN and they can tell you how it is equipped. Alternatively, you can test the wire you found with a circuit tester such as # PTW2993 to determine if it has power (the vehicle may or...

  • Troubleshooting Trailer Running Lights that Arent Working
    The first step to troubleshoot your problem would be to determine if the wiring problem exists with the vehicle or the trailer. Turn on the vehicle headlights, and use a circuit tester like part # PTW2993 on the pin on the trailer connector that feeds the running light circuit. If your vehicle has a 4-pole connector, test the pin being fed by the brown wire. If you are dealing with a 7-way connector, you would test the pin in the 11:00 position. If the tester indicates voltage on the...

  • Troubleshooting Weak Trailer Brakes on a Toy Hauler Even After New Axles
    This could be a magnet wiring problem. It is unlikely that the magnets are bad on new assemblies, but if the wiring is not properly connected, it could cause problems. Check to see that the magnets are properly grounded to a clean, bare metal surface free of corrosion. A bad ground would not allow the circuit to be complete and lead to the brakes not performing like they should. You can also try running all of the brake grounds back to the main ground of the trailer. The new brake assemblies...

  • Troubleshooting Low Taillight Circuit on Trailer Taillight Converter
    What you will want to do is test the wires going into the box of the converter box for voltage with a circuit tester like the # PTW2993 to see if there is voltage going into the box when the taillight functions of your vehicle are applied, and then test the output side of the box to see if the current is making it through the converter. If not then the problem is that the converter box has shorted itself out and would need to be replaced. Before you replace it you will want to inspect...

    CIPA does not provide the wire function schematic for your 1996 Chevy pickup, so I am unable to tell you the wire functions. You might be able to figure it out by using a circuit tester such as # PTW2993. What you would do is plug in your old factory mirror to the wiring harness and then probe each wire with the tester, one at a time, while using the adjustment knob to move the glass up, down, left, and right to determine the functions of the wires. Please note that the only way the...

  • Trailer Brakes Activate Every Time Turn Signal is Used
    It sounds like you wired the brakes into the combined stop/turn signal circuit on the trailer. Trailers use what is called a combined system meaning that the brake lights and turn signals are on the same tire. So when you are using the turn signal the wire is energized and will apply the trailer brakes when the light blinks. To use the electrical trailer brakes you have to have a dedicated wire just for the brakes and you must use a brake controller in the tow vehicle. The most common...

  • Weak Trailer Brakes On Trailer Towed by Ram 3500 or Chevy 2500
    Which brake controller are you using? What are the years of the trucks? If using factory integrated brake controllers you may need to adjust the gain (same on aftermarket controllers) to increase the output voltage. Trailer brakes work on varying voltages. At 4 to 5 volts that is not quite half of full power. At 12 volts the magnets would be fully energized. Also, where are you testing for voltage? Adjust the power output on the brake controller to the maximum and then have someone fully...

    To determine if the issue is on your 2012 Ram 1500 or the trailer you will need to disconnect the trailer and use a circuit tester such as # PTW2993 to test the vehicle side connector. With the running lights on, test the pins on the vehicle side connector. If there is no power at the connector, then the issue is on the truck. If there is power at the vehicle connector, then the issue is on the trailer. You can check to see if the tow package fuses and relays are present or just bad by...

  • How Do I Wire Utility Trailer that has 2 Yellow and 2 Green Wires
    My suggestion is to test the wires for function with the trailer connected to the tow vehicle. You will need a circuit tester, like part # PTW2993 and a 12v power source, like a car battery. You can then probe the connector with the tester to determine the specific functions of the wires. I have included a link to a wiring FAQ that explains the functions, wire colors, and size wire used on various connectors.

  • Troubleshooting Trailer Wiring When Turn Signal Is Not Working
    One of the most common causes of trailer light failures is the ground. You will want to make sure the ground wire is secured to a clean, bare metal surface and that there are no signs of damage to any of the wires on the trailer. Check the harness connector to make sure it is clean and free of rust and corrosion. If that all checks out on the trailer you will want to check the output from the vehicle with a circuit tester like part # PTW2993.

    Thanks for sending a diagram! The fuse panels on your 2007 Jeep Commander are located under the hood and on the lower instrument panel just to the left of the steering column. I did some research on your Jeep and fuse location number 21 (rear turn/taillights) in the front underhood fuse box is a 20 amp yellow mini fuse. Replace if blown. I would still take a look at your owners manual to confirm and I think it's page 399. I would also check your 10-pin connector for any corrosion and...

If you have no current showing there may be a fuse missing or blown for that circuit. You would want to check the owner's manual or with your dealership to see which fuse is dedicated to that circuit. There are times when the dome lights may be attached to the running light circuit.

With the brake pedal applied, you should get a signal both the right and left turn signal pin, as shown in the photo I've provided. If you or a friend have another trailer handy, you might try plugging that in, to see if the lights behave the same way. I'm doubtful it's a fuse, because the tow package on your Silverado combines the signal for the trailer turn signals and brake lamp...
