I cut the clamps off and replaced them with a cigarette lighter plug like my old Snap On. This one works quickly, has visual LED lights and auditory beep for voltage and ground. The tip is super fine and easily gets the recessed top pins on mini automotive fuses. Great tool!

If you find yourself trying to diagnose a problem a lot by testing wires, checking connections, checking fuses, etc. then get yourself one of these. I’ve been using my multimeter when, for a lot of the diagnosing, I could have just been using something as simple as this. Easy to use, simple easy voltage readout, one handed operation. LCD screen lights up blue for easy readout in dark areas. A bit bulkier than others that don’t have a voltage readout, but well worth it!

I am no mechanic by any means but having this tool, I can at least confirm some basic troubleshooting tasks before moving on. No more guesswork. Simple to use this and I should have added one to the toolbox a long, long time ago. Not too expensive either and seems to be good quality. Light is bright enough and gives an instant response to whether you have voltage or not. I can see myself taking on more projects by having this so hopefully it will save me some money too.

I do a lot of work on cars and motorcycles so I have a pretty good collection of tool including tools used for testing a variety of issues. This does the job of several and is designed in a way where even a novice diy user can quickly master it. Over a multimeter which is what i had been using this does not require two hands to test the circuit. The positive and negative grounds are clamped in place and with the 6 foot flexible test cord the clamps dont need to be constantly moved in order to reach. It makes troubleshooting a breeze for my 12 volt car and bike and even 24, 48 and up to 60 volt cordless tools and multi battery golf carts and higher voltage electric vehicles. The idiot lights are great for accidently reversing the polarity or higher voltages over 60v. Easily test for broken/disconnected wires, bad batteries, blown fuses or open circuits within the parts themselves no matter the direction of the flow. Easily cuts my troubleshooting time in half.
