This is one of those instructional vids that should be in the YouTube Hall of Fame. Excellent!

Folks that hate electrical work are probably folks that don't understand it. Thanks for helping us understand it a bit better. 👍

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.

I've been working on my own vehicles for 14 years and i just found this out, thank you!!!

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. 😊

EXCELLENT info. I recently had a blown fuse for my heater blower, and had no idea how to test it. Thank you so much!

You’re never too old to learn something new says this 68 year old :) good video!

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.

This is great info. I'm 74 and never knew this. Thank you sir

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 -

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.

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. :)

Funny it’s mainly only oldies who value lifelong learning. I’m 65 going on 95, now fully subscribed, thank you, brilliantly done.

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.😊

[HarryBurrTV]

Easily and by far the best instructional vid that I have seen. Congrats and thankyou.

[dhanashekarraju]

Sir, nice of you posting this useful video.
I learnt how to check healthiness of fuses, 👍.
Expecting more videos on cars 😊

[beanmuncha]

Thanks for this, on visual inspection the fuse looked okay but doing this it showed it had blown. Thanks again.

[vindicator]

Thanks for sharing this tip. It worked for me in just a few seconds. Sure beat busting the wrong fuse trying to get it out to check it.
