General Technologies Corp GTC CT8002 Cordless Circuit Tester, Black

Awesome tool, I work on a lot of heavy equipment(24Volt) and this works well, I can check an entire fuse block in the time it would take me to setup my mutimeter.

About the coolest thing i've seen for quick circuit tests for the price. Works as advertised. I bought several of them for a variety of locations and cars.

Great product, well built and functions the same

Easy to use. Good tool. Great price

After using one of these testers you will throw your old corded one away nice bright red light and beep lets you see and hear to see if there is power to the circuit you are testing without worrying about you ground wire falling off when you are upside under a dash or trying to get a good ground simply hold the tester and touch any metal part of what you are working on with any part of your body that has skin exposed forearm,elbow other hand etc many time you are already touching some thing that has a ground battery last forever this is my second one first one lasted me 3 years of hard use many falls and the battery was still good

The end that holds the battery has a screw that was put in sideways so hardly holds the batteries in, pretty cheaply made wouldn't buy again.

I was skeptical about it's ability to have a proper ground in order to work however this thing works fantastic. I'd also recommend buying the adapters for checking the fuse panels.

u cant see the red light ? u will hear the beep , u cant hear the beep you will feel the vibration .i bought my first one about 3-4 year ago ( without vibration ) , and i forget it in customer car so i bought 3 more and received it todayjust an amazing product , i test ECM without worry about damage the ecuhighly recommendedand ill bought more now :D

This is a very good find, you absolutely need this if you work on motorised vehicule, it's not only a time saver but it's totally removing those very uncomfortable moment when checking fuses and circuits with your back laying on a dirty carpet and your knees in your mouth with a multimeter in your hand trying to align both needles and looking at the screen and loose contact..A very practical lil tool, congrats on this genius invention.

el uso de esta herramienta te ayuda a no dañar un componente electrónico. buen trabajo¡¡

muy practico y comodo de usar,la uni cosa que no me gusta es que detecta incluso voltaje como 3v por ejemplo,me gustaria que detecte solo 12v pero aun asi considero que es una herramienta indispensable para cualquier taller auto

Awesome product, easy to use, very effective

happy happy joy joy . this one seems to be working fine .bought it to replace my cheap knock off one that died ,but now the old one is starting to work again .oh well one for home and work is fine.kinda fun lending it out sometimes and telling themyou are the ground wire .Great for testing if fuses are working in cramped areas.
