Mars 8577 ZEBRA SHORT FINDER PRO TOOL 1 Pack

Make finding low voltage short fast

I just wanted on for testing my HVAC

This tool is absolutely a must have. It makes it real easy to locate 24 V low voltage shorts.

This is NOT a Mars product, but a knock-off look alike.

i like , very good

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

Was able to find 24v short in air conditioner air handler in less than 5 minutes this piece works great.

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

Outstanding product

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.
