allsun Automotive Electrical Circuit Tester Probe 2-24V DC Pen Vehicle Power Diagnostic Tool Auto Wire Test Light Device System Analyzer

Got it fast and worked great. Went to use it again after having it a month and it doesnt work and Amazon wont let me return it or exchange it. Recommend not purchasing.

My children bought me a Power Probe as a gift a while back and it was amazing. I wanted a less expensive tool like it I could take for mobile repair work. This has done everything I’ve needed. Like Power Probe, it has an auxiliary ground and has a momentary switch to supply power. Very handy. It paid for itself with the first use.

This tester works great for diagnosing auto electrical faults. Especially appreciated is the ability to inject + or - through the probe tip. The voltage readout is analog via a series of LEDs, a little difficult to read, but serves the purpose. The single front LED is not very bright but again, it serves the purpose ok. Overall, this is a very good value.

El equipo es muy bueno más en aquellos vehículos que utilizan computadora para todo

Great quality, solid wires, selector switch, and clamps.

i got the tool but it came with no probe smh so now i have no way to use it

No f ing pokey thing Looking at a black plastic hole when i need it POS

I have something draining the battery in my Jeep. Can this tool help me find the culprit?

Very nice tester. The ability to apply power and/or ground to whatever you are testing is great. That feature makes quick work out of testing relays, bulbs, motors. Especially useful when testing power windows. It is a little bigger than its competition, the power probe, but significantly cheaper. I recommend having two of these. That makes some diagnosis even quicker. I am pulling one star because the power/ground cable does not have a strain relief and will bend quite a bit where it enters the tester. Over time that will cause cable breakage. By the way, the touch metal is for turning on the tip illumination. Touch the short ground lead to it and the illumination comes on. Another handy feature.

I just needed a tester for misc things. Works great
