Heavy Duty 3-48V Backlit Digital LCD Circuit Tester, Test Light with 140 Inch Extended Spring Wire, Car Truck Low Voltage & Light Tester with Stainless Probe

Es muy bueno pero nada más mide pura corriente no detecta tierra

I recently got a 12V test light for checking fuses and electrical circuits, and it has been a really handy tool. It makes it super easy to quickly see if a fuse is getting power without having to guess or pull everything apart. What I really like is how simple and effective it is. You just touch the fuse or circuit, and it clearly shows whether there’s voltage present. It saves a lot of time when diagnosing electrical issues, especially in a truck or car. The build feels solid for a basic diagnostic tool, and the probe is sharp enough to get a good connection without being difficult to use. It’s also compact, so I can keep it in my toolbox or glove compartment without it taking up space. Overall, this is a must have tool if you work on vehicles or just want to quickly check electrical problems. Simple, reliable, and very useful for everyday diagnostics.

The circuit board is blown after testing on the car on first attempt

This test tool is well made and seems to work well. the voltage displays accurately and the only downside is that it is not actually a "test light". But I like the tool and would recommend it.

It was great. Worked how i expected.
