    what does it test ? how does it work ?

    As far as I can tell you clamp the crocodile clip to any handy ground (eg chassis) and poke electric connections with the probe. It tests for closed circuits. If, say, your headlights aren't working but the fuse is okay then you could use this to find a broken or bad connection by testing the wire between the lamp and the fuse. Headlights need to be on for this.
