Mars 8577 ZEBRA SHORT FINDER PRO TOOL 1 Pack

Good

YOU SAVE TIME, FUSES, THE RESET CURRENT PROTECTION PROTECTS ALL CONTROL CIRCUITS WHILE LOCATING 24V SHORTS.EASY TO USE , WELL WORTH THE PRICE.

Excellent tool

a most have for finding a low voltage short in a hot attic. plus you will save alot of fuses

I havent found a short with them but they make great jumpers at a control board.

i like , very good

Received the non-Mars Short Pro and so far it works essentially the same. The original Mars/Zebra version (now called Short Finder and not available on Amazon) has a red led while the Global Amazon version has a blue led. The Mars version comes with alligator clips and quick connect terminals while the Global version has alligator clips only. The packaging is different as well. Both employ solid state current limiting for 24 vac short protection and both reset when the circuit is opened. The Global unit states it will allow 2.2 amps before current limiting. So a system transformer greater than ~50 va may not work with this troubleshooting tool connected in series.

Worked great for finding a short. Easy to diagnose also light weight. Highly recommend to part of the tool box.

Amazing product works great and as saved me time and money on replacement fuses

Great tool
