"Use Bulb To Check Short Circuits:"

From:  Brian Drumm tesco@ime.net

If you have a short circuit one way to tell if it is cleared is to wire a light bulb pig-tail in series with the problem circuit right off the breaker, or if edison base fuses are being used replace the fuse with the light bulb.
turn the circuit back on, the bulb should be full bright.Then start isolating the short by disconnecting things down the circuit.When found the bulb will dim or go out depending on what load might still be on that circuit.Fix the problem and remove the bulb.
