Video Transcript for Review of Performance Tool Tools for Wiring - Digital Multimeter - PT89ZR

Ellen: Hey, everybody. I'm Ellen here at, and we're going to take a quick look at the Performance Tools digital multimeter. This is something that's really handy to have any time you're doing any kind of electrical job, or you're trying to test out any wiring, maybe do some troubleshooting with some wiring that's gone bad, you want to test out your battery, really anything along those lines. So a lot of times these are just something that's handy to have in your toolbox for any of those sort of instances.inaudible 00:00:25 about this is that it does give you a pretty big digital display that makes it easy to see what's going on. You get the leads that are about 42 inches long, so should be plenty of space, or plenty of length to get connected to whatever you want. And then there's also the included attachments that have a little alligator clamp, so that makes it easy, especially for testing out a battery without having to hold the little prongs over it the whole time.

So let's take a closer look and kind of run through some of those basic tests that you might end up doing.So here's our little guy, we've got a little kickstand at the back, makes it easy to just set this on a surface, set it on your trailer, on the floor, and we'll still be able to see what's going on. I'm going to hook up my leads here, they are color-coded so it makes it easy to remember what goes where. Got a couple little ends going over the prongs here. You'd probably end up losing these, honestly, but they do kind of help protect these. They are a little bit sharp, so if you've got these in a toolbox, it's kind of nice to have the caps just to keep them from ending up in your hand.There's also a couple of caps going over these ends, which I doubt you'll ever use, unless you're pretty meticulous about taking things apart and putting them away.

I'm just going to connect this up here. Most folks like to just keep the leads attached, makes it a little easier, so you're not having to take things apart every time. I'm going to put my alligator clamps over so we can test out our battery first. You don't have to, of course, you can just put the prongs over and it's not really too hard. You just want to make sure if you are going to use these, the inside there, this might be kind of hard to see, there's a little sleeve that that prong needs to fit into.

So just want to line that up to make sure it makes good contact all the way around.To turn this on, you just need to turn the dial away from the off position. So I'm going to turn it around to the 12 volt DC portion so I can test out my battery here. Swing those guys over and then set up my little kickstand there, and then just want to match the leads to my battery. We got red going to positive, black going a negative. And you can see our display showing what's going on there, so about 12 volts, that's what we should expect to get out of this.

Now there is a hold button, it's going to be that yellow one kind of on the left-hand side, to freeze the display at whatever it's reading out. Sometimes on other multimeters, if you press that, it'll freeze it at whatever the highest rating is. But this, it's just going to freeze it at whatever it is at the time on the screen, so that's something to keep in mind.To reset it, just press it again. I've run into this, though. I'm not a huge fan of the way this functions on these multimeters, because if you don't have it connected, maybe you don't realize that you have the hold button pressed, so if you try to go and use it, it's still at zero, and it could be a little confusing. It might make you think that there's something wrong with the multimeter, but it's just that that hold is on. So as soon as we press it again, it's going to give us our true reading, but that's just something to keep in mind there.There is another multimeter available from Performance Tools that has a little bit bigger screen, and that at least does have a little indicator to let you know when the hold is on, which I kind of like, just so that you can, if something's going on and you don't realize the hold is active, it gives you a visual cue. But again, if something's going on wrong or you're just not getting a readout, or it's not changing, press that hold button and see what happens, and that should make it pretty easy.Another common way to use this is to test out wiring functions, so if you we're to plug this in and then you want to test what each port is to make sure you get things wired up, this would be another way to do that. So you'd have current going through, and then I think usually this guy is the ground, and then you'd want to run through all the functions and test out what goes where, so that's a pretty common way to do it. It does give you pretty long lead, so it makes it easy to fit that into any kind of wiring plug and get connected to make sure that you can test things out, do your troubleshooting and what have you.So all in all, this is a pretty standard multi-meter. As I mentioned, there are other couple available here at I'd say this is kind of the middle of the road one we have. Here's continuity, it does give you an audible alert. So if you want to test a fuse or something like that to make sure that there's continuity, you can use that function. It does come with instructions so that you know what all those functions are and kind of give you the tutorial of how to use it. But all in all, this one is probably the nicest, just because it is still a digital display so that makes it easy to see what's going on. But it's also pretty compact, so if you want something just a little bit smaller than the other ones, this is a pretty good option. And it does still give you those alligator clamp attachments if you want to use those to make it a little bit easier to test out something like a battery.That's pretty much all there is to it for our quick look at this digital multimeter. I hope that this has been helpful in deciding if this is the right one for you. We do have a lot of other wiring, trailer and RV accessories available here at, so be sure to check them out. Thanks for watching.

  • Troubleshooting a 12 Volt Fan Switch That Overheats And Shuts Off
    A Replacement Wall Switch # 344410TSSW12V may or may not fix your problem. It will come down to what exactly is causing the switch to overheat. If the 12V RV Ceiling Fan like # 344410TSDC36BNOKCY is pulling more power than it should do to a damaged fan it will cause the new switch to overheat as well. You will need a Multimeter # PT89ZR to test the power going to the fan motor. This fan is rated at 20 watts of 12 volt power which will be 1.67 amps of power(be sure to check your fan for...

  • Troubleshooting Taillight Wire Power at 7-Way Trailer Connector
    What pin of your 7-way are you testing? If you are testing the pin at 11 o'clock when facing the connection on your truck, you should have a reading anytime the truck is turned on for running lights unless you have turned off the running lights. All other plugs should be cold except the 12V at 1 o'clock. Use a multi-meter like # PT89ZR to check for the voltage reading so we can further troubleshoot. Is it illuminating the stop lights on the trailer or the running lights?

  • What Does it Mean When Draw-Tite Activator Brake Controller 5504 Displays Code SH
    The display code SH on your Draw-Tite Activator Brake Controller, part # 5504, can indicate that there is a short or overload condition in your trailer brake circuit. This condition may also result in the display showing a flashing OL code. Please refer to the included instructions from Draw-Tite for a description of all error codes. Either of these fault codes points to a need to check the brake circuit on your trailer. I have linked two help articles, one concerning troubleshooting brake...

  • Draw-Tite Activator Brake Controller Shows an Overload OL Condition When Trailer is Connected
    The OL on the display for the Draw-Tite Activator, # 5100, indicates an overload condition. This can be indicative of a short circuit along the blue wire of the brake controller. The short could be the result of a bad ground, broken wire, corrosion in the trailer connectors, or any combination of these. Start by checking the wiring at the back of the brake controller to ensure that the ground is connected to a clean bare metal surface if it was hardwired. You can use a circuit tester like...

  • Tekonsha Voyager Brake Activator Not Working On a 2006 Dodge Ram When Brake Pedal is Pressed
    First, you will need to test the red wire going into the back of the brake controller for 12 volt power, with a multimeter, # PT89ZR, when the brake pedal is pressed. If there is no power or less than 11 volts of power when the brake pedal is pressed, you will need to find a brake circuit that supplies at least 11 volts, 12 + is better, when the brake pedal is pressed. If your brake switch wire is connected correctly, then you will need to turn your attention to the brake controller settings....

  • Troubleshooting Furrion AC/ DC Panel Fuse Issue
    It sounds like you are using a circuit tester like # PTW2993 on your Furrion AC/DC Distribution Panel - Wall Mount # FDP12WABL which is good on the 12v DC side. It shows that you are getting power to that circuit at that location which leads me to believe the panel is not the issue but the fuse may be even if it doesn't appear blown. When you have power on one side, if it isn't transferring to the other side then the "bridge" is broken. You can check with the fuse installed if you get...

  • Intermediate Operation of Electric Trailer Brakes
    Sounds like you will need to check a few this to figure out your trailer brake issue. The first thing you need to check is if you have correctly set you brake controller to the proper setting for towing your trailer. Make sure to consult your brake controllers owner's manual for the proper settings. If you control has the correct braking settings, then you will need to check the brake signal coming out of the brake controller. The voltage leaving the brake controller should be 11-volts...

  • Troubleshooting Optronics Camo Nightblaster Spotlight
    I spoke with my contact at Optronics and he said first you will want to test the battery by charging it thoroughly. Once charged, test the battery with a volt meter, like # PT89ZR, at 20 amps. Next check to see if you are getting a reading of 12 volts. If not, the battery needs replacing. If the battery checks out you will have to replace the halogen bulb. To do this you will need to take apart the entire light. You will want to take photos to make sure you replace all parts correctly....

  • Troubleshooting 12V Trailer Power to Charge Dump Trailer Battery
    The 12v power output on your 7-way trailer connector at the 1 o'clock position should be tested. There is not a wire like in the older models that needs to be installed for that function, but if you aren't getting power when tested with a circuit tester like # PTW2993 or a multimeter like # PT89ZR then you will know there is an issue. You can check the connections for bent pins or the fuses and relays as outlined in your owner's manual. If you have power at that pin, then it is likely...

  • Troubleshooting An Everchill RV Refrigerator That Will Not Cool
    You'll first want to ensure that your Everchill RV Refrigerator w/ Freezer # 324-000119 is receiving a full 12 volts by testing the wiring at the fridge with a multimeter # PT89ZR. If you don't have 12 volts then either the battery isn't fully charged or the gauge of wire used from the battery to the fridge needs to be thicker to compensate for any voltage drop. From there you'll want also check the ground. We've had these fridges do some wacky things until we grounded them directly...

  • Troubleshooting Hopkins Reliance Brake Controller on 2008 GMC Sierra 1500
    The first suggestion I have is to replace the Hopkins Reliance brake controller, which despite its name is an unreliable brake controller, to say the least. You can still get an economical brake controller that is far more reliable with the Brake EVN # TK63VR with Brake Control Harness # 20127 for your 2008 GMC Sierra 1500. In regards to the issue you are having, an E1 code on the Reliance means a trailer is not connected and there are a number of potential issues you will need to troubleshoot...

  • Troubleshooting Tank Pad Heaters That Arent Operating
    The thermostat is built into the pads of the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000163. Your idea to put ice on the pads to simulate it being cold isn't bad. It sounds to me like you may not have the correct amount of voltage running to the pads (they require 13.5V DC). I recommend using a multimeter # PT89ZR to ensure your getting adequate voltage to the pads. If not then I would call LaSalle Bristol for a warranty replacement.

  • Troubleshooting A Lippert Ground Control 3.0 System That Won't Activate The Middle Legs
    If you went through the recalibration process on your Lippert Ground Control 3.0 Electric 5th Wheel RV Leveling System w Touchpad and Remote - 6-Point Set # LC675817 and the middle legs still aren't properly activating then I would first check that they have 12v DC power running to them with a multimeter # PT89ZR. If they're getting less or no power then we know the cause is the power source or maybe some damaged wiring. If power isn't the issue then it could be the touchpad # LC421484...

  • Trailer Brakes Getting Extremely Hot When Towing with a 2009 Ford F-150 and Brake Controller
    You do have an issue that needs to be addressed. With the brakes getting that hot, braking performance can be significantly reduced, your brakes will wear prematurely, and the tow vehicle is working harder to stop and most likely pull the trailer. I would start out checking the trailer connector at the rear of the vehicle, without the trailer connected. There is a possibility that mis-wiring or corrosion inside the connector is causing power bleed onto the trailer brake circuit, which...

  • Brake Controller Will Not Fully Activate Trailer Brakes On a 2014 Ford F-250
    The 5 amp fuse that you pulled is the fuse that is the brake signal that goes to the brake controller. This would only remove the brake signal of you pushing on the brake pedal and telling the controller to activate. There is a 30 amp fuse under in the engine fuse compartment that would deactivate the controller. It does sound as if there is something possibly wrong with the controller or the truck wiring. You can test the voltage and amperage output of the brake controller to the trailer....

  • Troubleshooting A Fogatti Tankless Water Heater That's Turning On But Not Operating
    Hi Jim, If your Fogatti RV Tankless Water Heater # LSB64FR is turning on but not sensing when water is passing through then you could either have a bad water flow sensor or there's the possibility that you have a shut off valve somewhere leading to the unit that could be turned off. A lot of RV's will install quarter-turn valves to separate the water heater from the rest of the plumbing so that they can run anti-freeze through the lines for winter. I recommend checking that your unit...

  • Thomas Payne Seismic Recliner Not Heating
    The Thomas Payne Seismic Left Arm Power RV Recliner w/ Heat, Massage, LED Lights # 195-000099,which is no longer available. does in fact have heating and cooling options. Start by checking the wiring of the heating pad for continuity when the heating function is turned on with # PT89ZR . If you are getting voltage but the seat still isn't heating you'll want to replace the heater with # 195-000113. If it's not the heating element, then it's more than likely the cupholder with # LC38FR,...

  • Troubleshooting A Lippert Ground Control 3.0 System That Isn't Lowering Middle And Rear Jacks
    To manually reset your Lippert Ground Control part # LC675817 you'll need to hold down the retract and enter buttons at the same time. I would also check the wiring with a digital multimeter # PT89ZR to ensure that you aren't losing power at the other jacks. If you do have 12v power at the jacks then I would check your ground wires for loose or corroded connections as a bad ground is the most common issue when it comes to wiring.

  • Tekonsha Prodigy P3 Brakes Only Work with Manual Override
    You should be getting close to 12v coming from the stop light switch, so it sounds like you either have a bad connection, or are not on the correct circuit. I recommend disconnecting this connection and searching for the correct wire where when the brake pedal is pressed, you receive close to 12v. You will want to use a multimeter like the # PT89ZR to conduct this test. Once you've located the correct wire, you'll want to re-attach and test everything out again to confirm that it is working...

  • Troubleshooting A Newer Lippert Flow Max RV Water Pump That Isn't Working
    When you checked the fuse did you test it with a multimeter # PT89ZR to see if power was actually passing through to the water pump or did you just look at the fuse to see if it was blown? It's also not uncommon for there to be an in-line fuse at the pump and another at the dc distribution board if it's not ran directly to the battery. The quickest way to test this would be to prick into the casing of the power wire right at the pump to see what the voltage is. If you're not getting 12...

  • Can The Green Light On A MaxxFan Deluxe Roof Vent In Auto Mode Be Turned Off
    The green light of your MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-07500K is going to stay on to indicate that you're in auto mode but could also be a indicator that your vent is either receiving more than 12 volts or less than 12 volts and is just trying to warn you that there's a issue. I recommend checking the voltage with a multimeter # PT89ZR to be sure. In manual mode the vent will not open or close unless you press the button or switch back to auto mode.

  • Need Replacement Trailer Wire Harness For 2019 Toyota Highlander
    Using a tester like Digital Multimeter with 42" Long Test Leads - LED Display # PT89ZR I would test the wiring starting at the factory plugs/connections and work your way back seeing if there is a short or bad ground. As well as checking all of your fuses just to be certain. If that doesn't work you can either have a dealer check it out and charge you an arm and a leg to fix it or you can bypass the factory tow package completely with the ZCI Circuit Protected Vehicle Wiring Harness w/...

  • Testing Electric Brake Magnets On Trailer
    There may be a problem with the brake magnets such as being worn till the winding are visible. You will first want to do a visual inspection for any signs of damage or excessive wear. You can test the brakes by turning the brake controller to its maximum gain and have someone apply the manual override. If you use a circuit tester like part # PTW2993 on one of the wires leading to the magnet you should show current. You can use a multimeter like part # PT89ZR to test the brake magnets....

  • Troubleshooting Signal Loss With A Furrion Vision S Camera System
    If your Furrion Vision S Camera System # FOS43TASF is working when connected to the monitor wire but not when connected to the rear of the trailer then you most likely have a power issue. The camera needs 12 volts to properly operate but the blue light will activate with less voltage. Most likely the tow vehicle isn't putting enough voltage out to power the entire circuit (lights, camera, etc.) so the camera isn't getting enough voltage to actually operate and pair to the monitor correctly....
