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

I mainly use the tr est light to test small circuits (turn signals, lights) on my motorcycles. The negative clamp is a little bulky for some applications. Otherwise, it works fine!

I am very pleased and happy with the design and quality of this product. It has a very large a LCD digital display which is easy to read in both daylight and darkness because it has a light. More importantly to me because I use it to test circuits in my RV, I needed to make sure it was accurate so I compared it to another more expensive tester and it was right on the mark. It has a very long cable and probe which makes it easy to get into those hard to diagnose areas. Finally while using it, I accidently dropped it and there was no damage which speaks to its durability. All in all I am more than satisfied in this product and it has exceeded my expectations in every regard so I give it 5 stars and an A++++++recommendation.

I was trying to tap into my low voltage (12V) landscape lighting with my low voltage (12V) step RGB LED lighting with no luck. Used this tool to check the voltage at the splice and although it would light up I couldnt get a digital readout of the voltage. Was getting rather frustrated that what I thought was a really cool tool was DOA. Took it out to the KTM motorcycle & it worked perfect. Hmmmmmm. Turned out to be operator error. The magnetic transformer puts out 12 VAC. The tool only reads 12 VDC. I did think it was interesting to note the tool would illuminate when exposed to AC voltage. It just wont give you a digital readout. Bottom line......Great Tester! Highly recommend.

This is a great upgrade to the old DC test light, it’s easy to read and the ground wire is extra long making it easy to test multiple locations from one ground location. Nice and valuable tool.

Works good. Only wish the clamp was bigger. The jaw doesn’t open as much as I would like.

Worked great well built

Works good

This item is of very high quality. I had the option to get one for a lesser cost but this one looked like the best deal for both quality and value. It has meant my needs and looks to be in my tools for many years to come. It is used for diagnostic of DC electrical continuity to find hot lines or terminals or broken connections. this one works all the way down to 3 VDC and up to 48 VDC so a wider range than other options. With a very clear digital read out which is nice to check the voltage as delivered to the prospective sight or terminal component. I used it for automotive at 12 VDC but can be used for computer diagnostics too as it goes down to check the many 5 VDC connections too.

Great tool, works great, easy to read. Quality Tool - The only thing I would change is the wire color, shoud be BLACK since it is the Black/Negative wire you will clamp to. Saves some confusion and follows color standards better. Actually, any color other than red would be better since it does have a black clamp cover to help.

Can only check power. not ground. so grnd to + ok// + to -, will not read. fyi
