Maglight continuity tester...

I did a spur of the moment car cdp install the other day for a friend of mine.
Ran into some "issues" with the original wiring the previous owner had installed & didnt have access to a  DMM at the time to do a continuity test.
What I did have tho was plenty of speaker wire and a mini-maglight flashlight.
Made a simple continuity tester to tra ce some wires under the dash.
Worked like a charm.
2 runs of wire is all that is needed. One to the "rear tailcap threads" and one wire to the center of the battery.

An example with 2 wires (alligator clips in this case) testing a computer power cable.
If I touched the green cable to the center of the battery inside the maglight the light would come on completing the circuit.
Easily done with bare wire, just have to hold it in place.

    Oh, Listen here mister. We got no way of understandin' this world. But we got as much sense of this bird flyin in the sky. Now there is a lot that bird don't know, but it don't change the fact that the world is happening to him all the same. What I am tryin to say is, is that the course of your life, well its changing, and you don't even see it- Forest Bondurant
