Video Transcript for Performance Tool Wiring - Tools for Wiring - PTW2993 Review

Speaker 1: Today we're taking a look at a hook probe circuit tester. Now, this circuit tester easily identifies shorts in six volt, 12 volt, and 24 volt circuits, fuses, test connections, and wiring harnesses. It's great to have around the house, it's great to have around the shop. It features a wire piercing molded hook that locks onto the wires to free your hands while working. All you have to do is push this up, it's spring loaded, place the wiring inside here. The wiring that you're wanting to test.

Let go, put your fingers on top, push down to pierce it, and that's all there is to it. The extended molded hook allows for testing in confined spaces or with limited access. It does feature a high intensity light bulb, and a four foot long cord, that's insulated and resistant to oil and heat.I'm going to go ahead and show you how to use it. I have a power box here, I'm going to zoom out so you can see exactly everything that I'm doing. I just have a power box that we use, mostly for testing lights and trailer wiring, and stuff.

What I'm going to do is, I'm going to turn that on, so with power running to it, that means that my 12 volt supply, which is my black wire here, has power. To test that, I need to hook this to my ground connection, it's just a big alligator clip. I'm grounded, and then I take this, open it up so that I have area or space to put my wire through, and then I just allow the little point to do its job. Push down, and then because I have power running to it, the light comes on.Now, if I don't have power running to it, it's going to identify that and my lights not going to come on. Again, it allows you to easily and quickly identify issues in your wiring.

It's a nice easy way to identify, and a nice easy to use system. That's going to do it for today's look at the hook probe circuit tester.

- PTW2993
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. 847531

  • Troubleshooting the Electric Trailer Brake Controller on 2011 Chevrolet Silverado 2500HD
    For your 2011 Chevy Silverado 2500 with integrated brake controller, the brake output wire will run directly from your controller to the 7-way. You can test the 5 o'clock pin of your connector for braking function using an incandescent tester like # PTW2993. An incandescent tester will draw power like a connected trailer would to give the unit signal that a trailer is connected to allow function. You can then use the manual override feature to test function. The light should get brighter...

  • Grounding Peterson Trailer Tail Light Part # V457L to Trailer Frame
    The Peterson Trailer Tail Light # V457L that you referenced is designed to ground through the mounting hardware which means that a bolt runs through the base which is attached to the ground circuit of the light and when it contacts the metal frame of your trailer the ground circuit is complete. If you wanted to ground this light with a wire you'd need to run the ground wire to the bolt you use to attach the light between the base and the trailer frame. The white wire on your 7-way wiring...

  • Fantastic Vent Ceiling Fan Won’t Open or Close
    The most common problem when a fan like the MaxxFan Plus Roof Vent part # MA00-04500K will run the fan but won't open is the Replacement Rain Sensor for MaxxAir RV or Trailer Roof Vent Fans part # MA34FR . I would first attempt to clean the sensor really well and check for operation. If it works your good to go. If it doesn't use the replacement sensor listed here.

  • How to Allow 12 Volt Accessory Circuit of 7-Way to be Active All the Time
    Sounds like you have a 7-way trailer wiring connector and the 12 volt accessory circuit turns off when the vehicle is turned off. The only way to bypass that so that the circuit is on all the time is to run a length of 10 gauge wire like part # 10-1-1 from the positive post of the battery through a breaker like # 9510 to the 12 volt accessory circuit of the 7-way which happens to be the pin in the 1:00 position.

  • Troubleshooting 7-Way to 6-Pole Wiring Adapter Operation
    It sounds like you are using a 7-to-6-way coiled adapter cable like # RM-1676-7 between your Class C Jayco Melbourne's 7-way and the 6-pole on your towed vehicle. Some trailer wiring testers that use LEDs may not always work correctly. If you have a probe tester like # PTW2992 I suggest you re-test the 7-way contacts one at a time. You can refer to the linked photo to see which pin to test for each function. The photo shows the usual RV circuit configuration but there are multiple ways...

  • Trailer Taillights Not Functioning, Reading 3.5 Volts at Trailer Connector
    The typical culprit would be a dirty or damaged trailer connector. Especially if the truck is more than a few years old. Take a look at the pins in the connector. If you see any white or green corrosion on the pins, there is the potential that the corrosion has spread to the interior of the connector and is interfering with the signal from passing through the connector. The # HM40975 would make an excellent replacement.

  • Troubleshooting Trailer Running Lights Not Functioning on 2013 Nissan Xterra Wiring
    The one missing running light relay is a common issue on certain Nissan vehicles. It is usually a missing relay in the in-cab fuse panel and it is # 38666-1 but you can check the owner's manual for all fuse and relay locations to verify. The relay is attached to a wiring harness which is located behind the passenger side kick panel near the passenger door (see picture).

  • Troubleshooting Intermittent Running Light Failure on 2017 5th Wheel Trailer
    I'll start off by saying that this could be as simple as a ground wire issue, so you'll want to make sure that the trailer end of the plug is grounded properly to a paint and rust free spot on your trailer and that it is secured tightly. If this doesn't correct the issue you'll need to locate the running light circuit on your trailer's 7 way connection, which when looking at the plug's socket, will be in the 11 o'clock position. From there, I would first make sure that the pin/blade...

  • Where is Cold Side of Brake Switch Normally Found
    The phrase "the cold side of the brake switch" refers to the circuit at the brake switch that carries voltage only when the vehicle brakes are applied. This circuit varies widely from vehicle to vehicle so the best way we can recommend you find it is to use a circuit tester like part # PTW2993 to test the wires of your brake pedal switch till you find one that only carries voltage when the brakes are applied and none when released.

  • Troubleshooting Wiring Brake Controller Into 2006 Ram Using Factory Wiring Labeled
    Thank you for the picture of the factory brake controller wiring in your truck that I believe is a 2006 Dodge Ram. I can tell you how it's "supposed" to wire up to your brake controller so that we can from there eliminate that as the problem and see where the problem might be. So the wire labeled ground goes to the white wire of the brake controller, the one labeled trailer brakes goes to the blue wire of the controller, the one labelled 30 amps max goes to black wire of the controller,...

  • Troubleshooting Trailer Taillights that Behave Strangely and Random Circuits Light Up with Blinker
    What you described is the classic and super bizzare insufficient ground scenario. It's hard to explain how it all works, but basically if you improve the ground wiring of the trailer you'll see that the lights will all come back like they should. Check the main ground wire that goes from the connector to the frame and then make sure all the lights are grounded properly as well.

  • Finding Brake Switch Output Cold Side for Electric Brake Controller on 2010 Jeep Wrangler Unlimited
    The cold side of the brake switch is located behind your brake pedal. You will need to use a circuit tester like # PTW2993 to test the wires to the switch. There will be a constant power 12v that will come into the switch and the wire you are seeking is one that has no signal when the brake pedal is not pressed, but has the signal when the pedal is pressed. So it is cold (not showing power) when the pedal is up and is hot (showing power) when the pedal is pressed. I've attached...

  • Options for 7-Way to 6-Way Adapter
    The Hopkins 6 Pole to 7 Pole Adapter, # 47435, does have a pin for the brake output for a brake controller. This adapter will work for your set up as long as the center pin of the 6-way plug on your RV is for 12v power and the pin in the 10 o clock position is for the brakes. You can verify this using a circuit tester like part # 3808. If the center pin on your 6-way plug is wired for brakes and the pin in the 10 o clock position is for 12v power, then you can still make an adapter using...

  • Troubleshooting 5th Wheel Wire In Junction Box That Isnt Connected And Error Message
    On your 2014 Open Range 5th wheel trailer, the color of wire unfortunately doesn't help. You will need to test the wire for function. Because you have the lighting functions, you may have a ground or reverse function. You may also have a brake that is not fully functional. I recommend tracing that wire and using a circuit tester like # PTW2993 to determine the function. I recommend connecting that single wire to a battery to see if you can quickly determine function.

  • Troubleshooting Trailer Running Lights Not Working with 2006 Nissan Murano
    There are a few possible reasons why the trailer running lights aren't working with the connector on your 2006 Nissan Murano. It sounds like you may have already done this, but if not, I recommend starting by testing the connector itself on your Murano with a circuit tester like # PTW2993. Test the running lights pin on the connector with this function activated on the vehicle to see if you get power there. If you don't get power, you at least know the issue is somewhere on the vehicle....

  • Installing Brake Controller in 1999 Toyota Land Cruiser with Factory Tow Wiring
    Because you have a plug under your dash, you will want to use a circuit tester like # PTW2993 to determine wire functions. You will need to find the 12V constant power and that will connect to the black wire of your brake controller. Then you will want to find the wire that only gives signal when the brake pedal is pressed. It should not give any signal without the pedal pressed, but should light up your tester when it is. This wire will connect to the red wire of your brake controller....

  • Troubleshooting Right Turn Signal Flashing Twice as Fast As Other After Harness Installation
    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56272 should not have changed the speed of your turn signal, so I recommend using a circuit tester like # PTW2993 to test the wires. Next I recommend checking the connections for bent pins and using a little dielectric grease # 11755 on the connections to give you a connection free of debris and moisture. Then doublecheck the ground connection on the harness. Make sure the connection is bare metal to...

    To locate the correct brake switch wire on your 2016 Mazda CX-9, you will need to use a circuit tester like # PTW2993 to test each of the 3 wires you mentioned in your question. You are looking for the wire that shows power only when the brake pedal is depressed and not for any other function like turn signals or running lights. I was not able to locate what color this wire might be in your Mazda CX-9, however testing the wires is still the best method as vehicle manufacturers tend to...

  • Troubleshooting Brake Controller Short Code
    Since you have inspected all the connectors, the short can absolutely be on the trailer itself. It can be in the wiring leading to the brake magnets, the brake magnets themselves, or a bad ground on an electric brake system. Because you referenced Servo, I assume you have hydraulic brakes and an Electric Over Hydraulic (EOH) actuator. This issue can only be between the electrical components in such a case, so it will not be all the way back at the wheel cylinder servo. I recommend...

  • Troubleshooting Tail Light/Running Lights on 2006 Class C Lexington GTS Motorhome
    I recommend checking your light bulbs first and then your ground connection as that is often times the issue if you have some functions and not others. You will want to make sure the ground wire is connected to bare metal and is free of corrosion or debris. If you ground connection is solid, then you will want to use a circuit tester like # PTW2993 to test wires and check fuses (check owners manual for locations). This will help you find a short in a wire if there is one so you can...

  • Locating Cold Side of Brake Switch Wire on 2016 Mercedes-Benz Sprinter
    In order to determine the correct wire in your 2016 Mercedes-Benz Sprinter to connect the brake controller red wire to, you will need to find the cold side of the brake light switch. Using a circuit tester like # PTW2993, simply test each of the 4 wires you mentioned to see which wire receives power only when the brake pedal is pressed, and not during any other function such as the turn signals or headlights. From what I could find, it appears the correct wire on your 2016 Mercedes-Benz...

  • Troubleshooting Trailer Taillight That Is Dim on One Side
    The right taillight/stoplight assembly has a weak ground. What you need to do is improve the ground of that assembly and it'll start working like it should. You can try cleaning how it attaches to the trailer if it grounds through the mounting hardware or you can run a ground wire back from the main ground wire of the trailer to the trailer connector.

  • No Power On Running Light Circuit Of Vehicle
    It sounds like either you have a bad ground on the truck at the 4-pin or 7-pin connector or there is a bad/missing fuse. Since you are not getting power at the running light circuit only, it is a good idea to check the owner's manual of your vehicle for the fuse location of the trailer tow park lamp or any other fuses related to towing in your vehicle. If you double check the fuses and there are not any missing or damaged, check the ground on the connectors to make sure they are grounded...

  • Trailer Brake Lights and Turn Signals Not Working When Running Lights are On.
    This is most likely a trailer grounding problem as indicated by your report that (all) trailer lights sometimes flicker and do not work at all if the trailer is not hitched (grounded) to something. First check the ground point at the tongue of the trailer. From the trailer electrical connector you will find a white wire. Follow that to the nearby end where you will find a ring connector crimped to the end and then screwed to the trailer frame. I would ensure that the ring connector...

  • Recommended Electric Trailer Brake Controller for 2018 Chevy Equinox with Factory 7-Way Connector
    I reached out to my contacts at both Tekonsha and Curt and they have not confirmed the wiring connections on a 2018 model Chevy Equinox. In previous years, there has not been a direct plug option for a brake controller but there also was not a 7-way factory available. It is very likely that there are wires under the dash that may work, but you would need to use a circuit tester like # PTW2993 to confirm. For a brake controller, I recommend the Tekonsha Prodigy P3 # 90195. This brake...

  • Troubleshooting Lack Of 12V Power On 7-Pin Trailer Connector When All Other Functions Work
    I recommend checking your fuses and relays on your 2016 Ford F-250 under the hood in the fuse box. I recommend also checking for loose cables and testing the wires with a circuit tester like # PTW2993 to see if you can isolate the short. If it is a factory 7-way, and both the fuses and relays are good and you can't find the short, you can either take it to a dealer to have them check it out or you can run a separate wire. To run a new wire from your battery, I recommend the # 10-1-1...

    I recommend using a circuit tester like # PTW2993 on the wires coming in and out of your switch. This will tell you if you have any power going into the switch or coming out of the switch when activated. It is possible you have a bad switch, and this will let us know if we need to trace a wire for a short or not. If you find that you don't have power going to your switch which is what it sounds like, you will need to physically trace the wire probing the insulation every couple of...

    Looks like you have a round 4-way connector in the picture you submitted. The colors you mentioned aren't totally a match for standard colors but they are close. Normally the colors are: White - Ground Return Green - Right Turn and Brake Lights Yellow/Red - Left Turn and Brake Lights Brown - Tail Lights You'll need to wire by function instead of color since yours aren't a total match.
