ZSPRT Zebra Instruments Short Finder (24 Volt Short Finder and More). Used to quickly locate shorts in 24VAC circuits while protecting controls from damage. The Short•Finder is a 24 volt system “short-finder”. It’ll keep the Tech from wasting a pocketful of fuses while trying to locate a control voltage short. A built-in circuit breaker turns on a bright red LED when tripped. As the Tech removes the short, the breaker can be flipped, the LED goes out, and the circuit is restored. Lightweight and compact, with two 18″ leads.
