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

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.

It is good product, i use it for PLC and also for car troubleshoot. Thanks

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.

I love this product works well makes life easier

Check parts on the car with or taking them out, love it

This power probe worked perfectly about 6 times. I went to use it today, and the red light and buzzer stay on constantly. This unit is 4months old and very lightly used, I expected it to work properly longer. My Sears multimeter is 12 years old and works fine. If my complaints to the manufacturer in China produces any results, I will update this rating. UPDATE: After a couple of emails, Customer support has determined a component failure and has promised to send me another unit. Good Customer support is hard to find these days.

Love it works really good makes wiring issues soooo much 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.

Easy to trace, a must have item!

If you do any electrical work or diagnostic work in the automotive industry you really need to get one and you can cut your troubleshooting time in half. I am speaking from 45 years in the automotive industry truth is it will surprise you.
