Great for testing circuits and loads Review: Fast Diagnostic Tool - First Impression - Easy to use. The bright color is easy to find in my toolbox. This tool streamlines electrical troubleshooting on the fleet I maintain. This works on tractors, trucks, trailers and agricultural implements. Any 12-24v DC system I take it to. On mine the tip will heat up until it glows when you power something, so be careful how long you hold the power button. I use it momentarily with no problems. The beeps and buzzers are impossible to ignore because they are bright and loud. That makes this tool safer IMO. There is no internal battery, which makes it even safer, and simple to maintain. The wires are long enough to reach the tail lights on almost anything. I really like it. It's intuitive, fast, brightly colored, and makes me look like I know what I'm doing even when I really don't. ## Features - 💪【15+ Diagnostic Car Services for Automotive System】Multiple functions - almost covering the probe tools on the market.

It will do both 12 and 24 volt systems. Does not work with AC voltage or current in homes **Q: Can you check for voltage by just holding the probe against a wire or do you have to pierce the insulation on the wire?** A: You have to pierce the wire. I suggest if you do, dab a bit of silicone sealant to the hole to keep out moisture and avoid corrosion. I would also suggest getting the back probe set to avoid piercing wires if that is a concern. **Q: Does the colour of the tool refer to any differences?** A: The picture is the real color, and the product is taken in kind **Q: Does this come with extension cable?** A: If you are working on trailers or the like you will need to purchase the extension. However the cord it comes with should be long (20FT) enough to work on any part of a car or light truck that you need to access. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by A***R on March 1, 2026* Very easy to read and use.
