Perfect for checking fuses, wires, and connectors, this tester helps you quickly track down power issues in 6V and 12V DC systems. The high-intensity bulb lights up the moment current is detected, giving you instant feedback without the guesswork.
The molded hook probe pierces the wire and latches on, so you don't need to hold the tester in place while you work. It makes multitasking in tight spaces a lot easier.
The 4' insulated cord gives you the flexibility to reach tight spots like under the dash or near the trailer tongue. It holds up to heat, oil, and grime, staying reliable through real-world garage conditions.

This is what I needed to track down a broken wire. I could hook it to the wire at the bqck of the truck and see what is going on from the front by myself
Amazing how quick y’all shipped it out
The tool is terrific and the service was outstanding. It arrived 2 days before predicted.
I bought this prob/circuit tester in order to make some minor electrical repairs to our Scamp 13. I carry it along on all our trips. It has been tremendously helpful isolating shorts that result from vibration and wear and tear. Furthermore, the tutorial videos here on etrailer have been equally helpful.
Easy installation.
I sold the trailer shortly after installing this item.
It worked well for the amount of time that I owned the trailer.
Haven't needed this tool yet but good to have it in my 12 volt electrical kit.
Cheap but does the job.
I had a tester like this years ago and I broke the end off.
I really liked the tester as you can hook it over a wire and probe it to see
if you have voltage.
Been looking for one for a long time.
You can find cheap junk ones but this one is just like the good one I had years ago.
Glad I found it and is is very well built.
Should last me a long time.
Was shipped fast also.
Will try and not break this one.
Thanks e trailer.
Looks to be well constructed & easy to use. Frees up your hands for other tasks, & has many other circuit tracing applications as well.
Probe works really good

Tester has worked out really well, only used it a few times
Quality item. Works great for quick DC tests.
I have yet to use it. It looked like something I should have so I ordered one.
Easy to use and definitely helpful when looking for a specific wire.
Simple tester, does what its supposed to do.
