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

great for troubleshooting trailer wiring, testing lights, etc. Sort of wished I bought the one with a digital volt read out, but I can get by fine with this. Long cord and sharp probe.

Easy to use

It looks like this equipent will do a great job. Didnt try it to find a short

The long cord came in handy for diagnosing a fuel pump issue. The ability to energise a circuit was a great advantage. This makes troubleshooting a circuit a lot easier.

It works and made a nightmare very manageable. It made what I thought was going to be a nightmare, finding a shirt in my wife’s car, relatively easy to find. Save me hundreds paying someone to do it. Just read the instructions if you never used one and take your time.

Works good, fast shipping

This was a great investment. Once you figure out how to use it, its great. I had to watch a few YouTube videos in order to understand exactly how it was working. Once I did, it worked great.

This works very well,

I couldn’t tell you if this is a good product because it didn’t come with the probe.

This unit works great for the function of witch it was designed. Dont spent a lot of money on the same thing from other brands this one works just as good.
