This handy short circuit locator allows you to quickly and easily find shorts in 24VAC systems. The automatic reset circuitry protects controls by detecting shorts and illuminating an indicator light. When the light is on, a short exists. Simply remove connections until the light goes off, indicating the short is fixed. It features 12-inch leads terminated with alligator clips for flexible connection to wires. No need for an assistant - you can troubleshoot shorts on your own quickly and safely. Just attach the clips, watch for the light and follow it to the short. Its simple one-button design makes it suitable for technicians and DIYers alike. Fix shorts fast without risk of further damage to equipment.
