General Technologies Corp GTC CT8002 Cordless Circuit Tester, Black

looking good

good tool

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 today just an amazing product , i test ECM without worry about damage the ecu highly recommended and ill bought more now :D

Useful tool, no need to clip on a ground wire just touch a bare body part or fastener. The point is a bit fat and clumsy, it could do with a real fine needle point or a proper wire gripper/piercer like a test probe to cleanly penetrate the wire insulation without damaging the wire.

Works as it should. These guys are worth their weight in gold around my shop

I really like this tester but it doesnt replace a traditional test light. It is extremely sensitive and will alert even if there is only slight voltage present in the system. I like having this in my pocket for times when I need to do a quick test to see if there is power. It also helps that this is safe for computer circuits. I also love the Camco 63928 Quickee Circuit Tester because it uses an incandescent bulb (traditional test light). Sometimes it is necessary to place a small draw on your circuit and observe what happens next.

Works fine. Not consistent. but it works. Actually Ive had it a year and it still work.

Very Hard to Find This Brand, But worth it

only tried it .seems to actually work.great idea if it works consistenly

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.
