Just reading the thread on trailer fog lights reminded me how easy any electrical work has become since I bought a power probe (pic below) a few years back, it allows me to keep the smoke in the wires (most of the time!) - its proven itself time and time again.
For those that dont know what one is, essentially is hooks onto the vehicles battery and then gives you the ability to touch a terminal and it will read voltage, or tell you its an earth, you can press a button and add power (or negative) - brilliant for testing relays, working out what a dash wire does etc.
So my question is, what have others found makes them look a bit more competent than they should really look?
