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....

@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.

Dave, that;s a neat little circuit. Looks like a 12V buzzer with a bulb or LED. It also puts a load on the short circuit so replacing the fuse with it won’t melt the car wires. I guess you just keep moving wires or unplugging stuff until the noise goes away. Cool. /John

@Thegarmendia
Thank you. I have fun posting these videos, and I try to make them as accurate as I can. But you should know that I don’t do this for a living, so it won’t be long before your experience will outstrip mine. Thanks for watching.

Thank you for showing this. As someone who is starting out in the automotive field I really appreciate this. Hopefully you will decide to post more of your knowledge on here.
