Hi,
I have a short circuit some where in my truck 12volt wiring, and was about to purchase a Short Circuit Detector ($30.00). I have never used one of these and am not sure if they even work. Providing they do, it seems like a simple device. Does anyone have design plans to build such a device. Thanks.

Sorry I never heard of a "Short Circuit Detector".
But a Mulitmeter which is partly also an Ohm Meter would probably be more practical.
Zero Ohms is a Short circuit.
On the other had, What make you feel you have a Shorted Circuit?
Blowing a Fuse?
NEED MORE INFO ON THIS!

Short circuits in vehicles can be either easy or very difficult. Often they occur, particularly with older trucks, in the lighting circuits-- tail light, turn signal, etc. If this is the case, check for corrosion at the sockets or wiring plugs. Other electrical problems, such as in the main wiring harness and under the dash usually require some sort of wiring diagram that is color coded.
It's hard to know which wire goes where!

Here is a link to the product I saw: www.brandsplace.com/0384-kdt2524.htmlHere is a page describing how to use one: www.inliners.org/tech/tech6.htmlThere are more expensive ones sold for $300.00 or more. It is in the lighting circuit, so I will check for corroded sockets as suggested, but fear it is in the wiring harness and the "detector" is supposed to allow one to find the short through the upholstery. |

The method described is used by all auto mechanics. Assuming you have a knowledge of voltage, current, and ohm's law, I say go for it. But be patient! Short circuits can be extremely hard to find sometimes. I have an experienced Toyota mechanic next door to me and I've seen the problem cars he has worked with. The write up above looks good to me.

Sounds Interesting.
I would also be interested to hear your Test Results aftewards.

I will give it a try soon and be sure to write about my results. Thanks for the help.
