I tell you this has been my life for over 60 years 60 years with electricity airplanes cars trucks when I walk out to their car and and just a few minutes to say it is a blown fuse now white I will put a new fuse in and see what happens
electricity in autos is way different than buildings though. i have no issue touching the positive terminal on a battery. touching positive in a home/business .......hell no
You made it simple for guys like me....having very less knowledge about these things. Thanks a lot for the help. Life seems easier with guys like you around. 😊
Any time I need to find a blown fuze or relay, I just take the fuse block off the car and use my bench top power supply to put 80 amps through it. Now they are all blown and I can't be wrong.
Thankyou sir, driving last night and put the dipped headlights on, all lights went off! Pulled over, switched off, switched on. No rear lights, dash lights, horn. Brake lights work though! Picked the tool up today, dark now but will test all tomorrow. God bless ,❤️👊
I worked on cars for 40 years, 30 for a fleet, and nobody showed me this trick until now, thanks OP. Also I wanna point out one thing and that is, always use a fuse puller tool if you can! Sure needle nose pliers work, sometimes, for some fuses, if you even have space for the jaws to move, which half the time you don't! Plus it is way too easy to mangle a fuse using the needle nose, you might even short something out -
Nice tip. I've been working on the family cars for nearly 60 years, and never thought of, or heard about this technique. I've had a test light in the drawer for decades. A nice simple time saver, with a nice simple explanation. Thanks....I'm subscribing 🙂
They also make those test lights that will glow green if the probe is on positive. But you can clip the alligator clip to a nail, or small screwdriver, and test wire to see which wire is positive or negative. The test light will glow red if the nail side is positive and the probe side is grounded. Comes in handy for testing polarity on ganged socket plugs in wiring harnesses. Sometimes you can't figure out whick wire is grouded but you know where the positive (power lead) is and you just alligator clip to the positive and probe to find ground.
Want to say thanks for the video, it's the one video that I could understand. You made the video to the point and simple. The way all videos should be.😊
Thank you, always great to brush up on troubleshooting tips. I always keep one of these testers in my car's tool kit. Fuses always seem to blow at the most inconvient times, it's good to know how to quickly find and fix the bad fuse.
Thanks for the video ... I have a test light but I never knew about testing fuses this way. I had always pulled them and looked at them with a magnifying glass. Subscribed!
Excellent video, great technique ... Q. why do fuses naturally blow with age? (ie: without overcurrent) A. fuses are designed to blow by melting when too hot with overcurrent, hence under normal usage they run warm, so over time the fuse-metal crystalline structure suffers atomic migration which causes physical internal flaws to develop and finally an ultimate failure to conduct electrons (current).
@@dontuno Sure, my explanation covers the fuses that prematurely blow, it's not about all fuses ever made, most stay within their design parameters. It's much the same with incandescent light bulbs, most eventually blow in time but some never do ~ best example is a light bulb somewhere in the US which still works today and has been permanently 'on' for over 100 years.
This is AMAZING!!! Tbh, you should put some keywords into your content that are for women, auto help for women, etc. Because as a gal, that has never done anything with cars (hush men viewers, I know, I know 😂), you made this so simple!! Now off to see if you have other videos about the other stuff happening lol. 2013 Acura TL - DRL error came on few weeks ago, then suddenly was gone so I dismissed it. Week later - battery completely dead, but when we popped the hood… the accessories came on. (🤦🏼♀️). Now another week or two, and suddenly my low beams don’t work, but high do. Seems to me like it has to be something electrical rather than fuse just based on all that has happened, but just started watching videos 10m ago to see if I can find answers/things to try. SMH - I need a man!!!
I flunked shop class in HS in the 70s; now I'm taking Shop Class 101 on You Tube. I'm starting with the fuse checks because my life has not been very bright overall. :)
Well known but excellent test procedure.. & worth repeating! However, please fix the start drag volume! I grew up on drag racing, but DON'tT wish to wake everyone in the house when watching a video early in the day!!
For me it's easier to just use a tester and measure the continuity between the two test points, that way you don't have to worry about it getting power. Great video anyway
Tomas, that way works for many, the issues I have with it are: it's a fight for space and hand room when the box is way up under the dash and though few if any fuses do, some circuits operate on 5v and sending the 9V from the continuity tester through that circuit may release the smoke genie or damage componemts. I hope your way continues to work well for you. Thanks for watching and commenting.
Great info and instruction, thank you for posting. One question, if I can't find the removal tool how can I get them out? I tried thin nose pliers, but I couldn't get them out. Help advice please.
Thanks for the tip, I’m having the same problem on my 2011 Camry with the headlights and fog lights the fuse lights only lights up on one port thanks a lot 👍🏽💪🏽💪🏽
I have heard these test lights called by another name: "scope on a rope". I had a battery blow up on me. I got covered in acid. Jumped in the shower with my clothes on. Quickly rinsed the acid off my face, hair and exposed skin. Gradually took off my clothes and put them in the washing machine. Then I washed all over with soap. Luckily no damage to my eyes because I flooded them with water so quickly. Now I wear safety glasses anytime I am around battles. My friend is a mechanic. He has had two of them blow up on him.
I also have heard of many automotive shops in the northern US states actually snipping fuse output legs on their customers vehicles and turning it back over to them, such a pity...😢 as for myself i am from louisiana, down here folks are raised on a totally different set of standards. Dont really have to worry about that type of thing. Every auto mechanic for a 100 mile radius are small mom and pop business most all of which practice honest morals. If this inflation would ever go on and drift its way up out of here i feel like everything might actually be alright on this end. Yall have a nice evening 😌
@@alive-awake if you snip the output leg of the fuse then when you test on the nipples, you get power on both sides of the fuse but the circuit will not work. You are breaking the circuit on the other side of the test point. The customer has a circuit that doesn't work and someone testing the way you are, picks up no fault. You have to remove the fuse to see the issue.
is very informative to "check" a fuse to see if it is blown, but actually "finding" the one that is blown, is going to take way longer than 3.7 seconds hehe
I subscribed! Man, no one ever explained about the one-side out fuse. If one side of the fuse is out that means the fuse is bad. That was a question I had and no one else mentioned. See, its little teaching tips like that make all the difference is us DIY guys to increase in knowledge and understanding. Furthermore, it saves us time and money. Another factor was you explained that some fuses are spares and sometimes the key must be turned on to make some fuses illuminate when tested. My question is this. On a 2015 Regal, 2.4L 4 cyl 8 fuses with not light up when I test them. I am searching for the blower motor fuse. I see no such fuse on the fuse or relay schematic located on the underside of the plastic fuse box cover. The blower motor does not come on. How can I locate the appropriate fuse or relay? Could you illustrate how to remove the blower motor on the above-mentioned car and the blower resistor? My 2004 Grand Cherokee, straight 6, 4 cyl blower motor has gone out too. Thanks for you help.
I use a multimeter. Set it for dc volts....probe across the little metal pips on the fuse. If you get little to no volts, the fuse is good, if you get the battery voltage (11-13 volts) the fuse is bad. Do this with the fuse in-circuit.
You will also get zero v if the circuit is off, like the headlights shown here☺ edit sorry you did mention that, but I was confused so ill leave my comment here too.
That method works well. What I don't like about it is when I'm in an under dash fuse box and I keep needing to turn my head to look at fuse and then dvom, then fuse then dvom. Etc...... so this way works for me. I hope your way continues to work well for you!
There’s no need to check both sides as one side is supply other side is load just check load sides only, same side on every fuse if no power then check supply side,easy faster.
I appreciate your time saving idea, but haven't found the supply side to be the same side of each fuse in all fuse boxes. Regardless, I hope it keeps working for you.
How would you if possible test fuses in the rear compartment fuse panel? I have a 2018 Chevy Equinox, I would need to test the back panel and under my steeling wheel. Des the tool come with an extension at all?
A voltmeter would be better to have than a test light because of its versatility for making other measurements. With a voltmeter, set it to measure DC volts. Place the probes on the test points on the fuse. Polarity doesn't matter. If you measure zero volts, the fuse is good. If you measure 12 volts, the fuse is blown.
While that works for some, it is rather cumbersome while under the dash upside down, looking at fuses, then turn head to look at dvom. To each their own, I hope your way continues to work well for you.
@@BaldwinsBowtieGarage Good point. 👍 Still should have a DVM because if the new fuse blows, then you'll need to measure resistance to ground on either side of that blown fuse.
great video! can a bad fuse cause lights like back lights on certain switches on the steering wheel and switches under the radio like the ESC and emergency trinagle switch to stay on causing battery drain? thanks again for great video.
Generally, a bad fuse will not allow power past it. So the fuse itself, won't cause that. But a vehicle may use the information of a system without power to illuminatr warning lights. A parasitic draw test is what you need to do.
Wow, 68 here and never knew that. I checked my older, next size bigger fuses and they also have access to check without pulling. Not sure but aren't headlights on a thermal breaker and after turning on headlights you're checking running lights? Excellent video, Thanks.
Thanks for your video. I was checking them Wrong . Only in one side!!😮 Now I will check both sides . Make more videos I will watch them. And I suscribe. 😊
Great video. Thank you. I have a question…my 2018 Buick Enclave has a dual usb port at the front (underneath the ac controls) that doesn’t work. All the fuse box diagrams don’t point out the fuse that is responsible for this USB port. They talk about the second row and the third row USB ports but none for the front. I can’t even find it on the Buick website and all these youtube videos on replacing fuses. don’t discuss which fuse it is. Any recommendations?
@@BaldwinsBowtieGarage Ah, good to know. Obviously I wasn't paying close attention to the video as I thought you were connecting the cable to the power terminal on your battery, not the ground. But now that I think about it, that would be stupid. Thanks for setting me straight and the tip.
This is a dumb question, but is the cord to the battery on the tester long enough so that you can test the fuses inside the car under the dashboard; or do those inside-the-car fuses require a different type of testing device?
Unless you have a fused 5V reference circuit, that you just sent 9V into with your continuity tester and release the smoke Genie. It's a bad habit to probe circuits for continuity, you should isolate the part being tested first. But, to each his own.
While you could test continuity to check a fuse, what happens when the circuit has a short to power? Nobody wants to pull the fuses first. Also, if you've ever had to do it under the dash laying on your back, you'd know that placing both probes simultaneously in a fuse while trying to see what you're doing is an exercise in frustration. Also, don't start probing random circuits with your ohmeter/continuity function, 9V into a 5V circuit is detrimental to some components. You can thank me later.
@@BaldwinsBowtieGarage everyone knows a little bit about electricity would not do a beep test with the system on, of course you must unplug the battery before beeping 😗
So to test headlight fuse turn headlights on, when headlights are shining, then test fuse. If both sides of the headlight fuse have power, then the headlights are indeed on. 😉
It amazed me how many people do not know very simple things. But it's a lot simpler to pull it and see if the link is burned-out. They have been making fuses where you can see the link for years. What you showed was backwards you don't check all your fuses then go to I think you called it the map to see what it goes to. You know something is not working so you go to the fuse diagram and it will say what fuse to check.
Well, normally, I do know what circuit is at fault, and check those fuses first. But many times a car comes into my shop with no manual or diagram on the fuse box cover. I can take 6 minutes to pull up a diagram on shopkey or all data, or in less time than that, I can check them all and move on. Time is money. I hope your way continues to work for you.
@@BaldwinsBowtieGarage Great video and explanations! Would be nice to show the burned link for anyone who hasn't seen it before. Have you ever had a case where the fuse was good, but wasn't making contact on one side? Could be a good time to know the 'look and see' method.
Thank you for the kind words. I have run into that with relays, but never yet on a fuse. I agree I probably should have showed a burned one. Thanks for watching.
Of course... since you have a "map", it's completely little-girl silly to test any fuses for stuff that still works. Only test the fuses that power stuff that doesn't work.

Locate the relevant fuse, do a visual to see the broken inner wire --- ,and if you can't ,just whack a new fuse in , test the circuit that way.

What if your fuse box is under the steering wheel and the battery is under the hood? I guess you need some sort of an extension for the power line.
You can use unpainted metal under the dash as ground.
@@BaldwinsBowtieGarage Ah, good to know. Obviously I wasn't paying close attention to the video as I thought you were connecting the cable to the power terminal on your battery, not the ground. But now that I think about it, that would be stupid. Thanks for setting me straight and the tip.
Ground
Brilliant video and so useful thank you 😁
All short -n- sweet common sense to the point bo bULLsH!Te.....info ! Worth my time & worthy of praise to you !
Thanks for this, peace & GB ALL
This is a dumb question, but is the cord to the battery on the tester long enough so that you can test the fuses inside the car under the dashboard; or do those inside-the-car fuses require a different type of testing device?
You can use any UNPAINTED metal as the ground connection for your test light. Like a bolt under the dash. Good luck and have fun!
Thanks sir..very good explanation and easy way to taste fuse..Watching from France..
You are quite welcome. Happy to help. Let us know what else you'd like to see!
Do a video on how to find a circuit that drains the battery over night. Thanks...
That is a very good idea! You rock!
Get a multi meter or a test light saves stress
Can you get the same thing with a multimeter ?
Great video!! Thanks for sharing 😊
ty but do you have to ground on the car battery only? if so, what if tester does not reach fuse in question.. ty haus..
Good advice.
Thank you
Leave ignition switch OFF. Use a continuity tester, much faster . No continuity equals blown fuse
Unless you have a fused 5V reference circuit, that you just sent 9V into with your continuity tester and release the smoke Genie. It's a bad habit to probe circuits for continuity, you should isolate the part being tested first. But, to each his own.
Holy crap I wish I took shop class in school
Everybody should!
very helpful. Succinct, clear instruction.
You can use a Multimeter to beep test the fuse in less than 1 second
Thank me later
While you could test continuity to check a fuse, what happens when the circuit has a short to power? Nobody wants to pull the fuses first. Also, if you've ever had to do it under the dash laying on your back, you'd know that placing both probes simultaneously in a fuse while trying to see what you're doing is an exercise in frustration. Also, don't start probing random circuits with your ohmeter/continuity function, 9V into a 5V circuit is detrimental to some components. You can thank me later.
@@BaldwinsBowtieGarage everyone knows a little bit about electricity would not do a beep test with the system on, of course you must unplug the battery before beeping 😗
So how do I use the multi meter to do the beep test without blowing up anything. Please can someone explain layman’s term. Thanks
He means a continuity test, but it's not the right way. A short to power will cause a false positive, battery installed or not
So to test headlight fuse turn headlights on, when headlights are shining, then test fuse. If both sides of the headlight fuse have power, then the headlights are indeed on. 😉
2:49 the headlights lighting up when the headlights switch is turned on indicate the good headlights fuse and no extra fuse testing is needed 😂
How do you test the big 30 amp breakers in a 94 Chevy 2500. Same way?
Thanks for the info...
It amazed me how many people do not know very simple things. But it's a lot simpler to pull it and see if the link is burned-out. They have been making fuses where you can see the link for years. What you showed was backwards you don't check all your fuses then go to I think you called it the map to see what it goes to. You know something is not working so you go to the fuse diagram and it will say what fuse to check.
Well, normally, I do know what circuit is at fault, and check those fuses first. But many times a car comes into my shop with no manual or diagram on the fuse box cover. I can take 6 minutes to pull up a diagram on shopkey or all data, or in less time than that, I can check them all and move on. Time is money. I hope your way continues to work for you.
@@BaldwinsBowtieGarage Great video and explanations! Would be nice to show the burned link for anyone who hasn't seen it before. Have you ever had a case where the fuse was good, but wasn't making contact on one side? Could be a good time to know the 'look and see' method.
@@BaldwinsBowtieGarage Thanks for responding hope you have a great day.
You betcha, you as well.
Thank you for the kind words. I have run into that with relays, but never yet on a fuse. I agree I probably should have showed a burned one. Thanks for watching.
Of course... since you have a "map", it's completely little-girl silly to test any fuses for stuff that still works. Only test the fuses that power stuff that doesn't work.
Niice. Does the car need to be on?
