Short Circuit Detector, Automotive, DIY, blown fuse

This video describe how I made a simple and inexpensive short circuit detector for automotive troubleshooting. The devices is designed to help find the source of automotive short circuits and blown fuses.

This video is published for entertainment purposes only, and it is not to be construed as an instruction guide. If you need help with an automotive problem you should carefully assess your limitations, and consider consulting a professional before getting in over your head. Be careful to protect yourself and to protect your property by not doing something you are unqualified to do....

did you finally figure it out to make a DIY frecuenzy receiver like the power probe pprect2000? here in my country is400$ hahaha iwill never pay double to those thieves,,i will try to find a relative living in USA to send me 1 cause the receiver makes it easy,but if i cant find no relative can you send it to me i will send you the money 1st,i ll have to trust you i can pay for your favor,please answer via private messaje

@serchmarc It's on my list of things to do next year. I made a little pulse wave modulator with a few parts last year, and I think that device would make a detectable signal that could be picked up by headsets. The main worry I have is not to give it too much voltage, since I wouldn't want to damage any sensitive electronics. Briansmobile1 did a video review of a relatively inexpensive tool, but it's still $100+.

@spelunkerd i couldnt find the video of briansmobile1,i also search it like briansmobile1 short circuit,but nothing do you have the title or the link? i watched the video that is on the right of the screen from pico3423 using a cranck sensor and headsets too,he doesnt xplain how to but if you know some of electronic is possible to make 1,but no indication ,increasing frecuency not voltag you can trace the signoal from your DIY singal module and listen for the open or short.what do you think?

[spelunkerd]

@serchmarc For some reason Youtube won't let me post the link here so I sent you an email.

i didnt understand how this can find a short circuit,,i just know a short circuit is a positive touching negative and then sparks coming out,sorry but my knowledge is limited in that area,forme thats a short circuit,how can this tool can find it??????????????

[spelunkerd]

@serchmarc For a high amperage short, the device adds enough resistance to keep the short going, to allow time to find it without constantly blowing fuses or overheating wires. With the light and buzzer, there is instant feedback that the short is active. You then trace the wires back and wiggle them, and disconnect at connectors. If the buzzer suddenly cuts out or wavers, you've found the short. Look closely at the wires at that point to find the short to ground. Thanks!

@spelunkerd i really apretiate your time

that video i saw it before but i didnt give importance

now that i watched completely

i can tell

is tha same job as the power probe but cheaper

kind off hehehe

cheers

and thanks again

holy shit bill nye tha science guy lol

[alken26]

reason i ask was that i have large bus iam work on at work and it blow fuse rather quickly can one of those tone generator be use with you diy system to pinpoint short in a large electrical system. ill tell you this your diiy short finer works Great THANK YOU keep up the good work.

@alken26 You make a good point, and I think it would be easily possible to build such a radiofrequency receiver that picks up local current. Ideally it would be best to have a transmitter that sends a signal that is easily recognizable, with a receiver and a headset. Such a device is available commercially for about $100. With sensitive electronics in some of these circuits, there is some risk to pumping in extra current. No such risk for the device described in this video.
