Works great!!

Good for testing car fuses..

Good

This tool is absolutely great but there is an issue with using this tool for what it is intended for, checking a circuit. Now I had a very simple low votage parasitic draw in my Harley Davidson. When I mean parasitic draw I mean under 0.007. I would normally pull out my multi meter to check the votage. My wife being the sweetheart she is purchased this tool to make my life easier. I used it, I found the draw was coming from my rectifier but this tiny draw ruined the LCD in the circuit tester. I went back into the Amazon app and purchased another one because it was as precise of my very expensive multi meter. I also bought 2.5 amp fuses and installed it where the springs are located. Problem solved. Now if JTS Jastind would simply install these fuses it would beat the other competitor who sells this tool for $150 (S??P-O?). I also see they sell extra LCD on Amazon. Make the product better please and give us the customer a better tool with an inexpensive fix. Could be 5 stars. I'll give 4 for being cheap.

Bought this to troubleshoot terrible light set bout on this platform. Turns out the trailer lights I got were totally defective. Used this tool to verify current throughout system and found that all parts of the light set was trash. Did the same on old lights off a tow dolly I rarely use and now have to trailer fully serviceable with the 5 y/o lights. Thanks to this tester, I didn’t waste any more money than I’d already spent on another faulty product. I can see using this for years to come.

Makes quick work of troubleshooting automobile, electrics

I like it I don’t want a meter with all of those fancy functions that I don’t know how to use. I just want to know the voltage! No internal batteries to die.

Upon opening the packaging I could see I was impressed with it’s visual quality. I took it out to the garage to see how it works on my own pickup. I grounded it to the body and touched it to the positive post on the battery. I quickly noticed that I had the LCD window turned away from me and when I went to readjust the tester stopped working and I couldn’t make it work again, so by now I’m pretty angry. Upon a visual examination I noticed the cord end screws off so I remove it to see if there might be a inline fuse but it was only a spring to hold tension between the cord and volt meter .mechanism. I cleaned it off and put it back together and it started working again with no more mishaps.The numbers aren’t clearly visible until you have the LCD window at the perfect position which might pose a problem when you’re in an awkward position and can’t move to see it perfectly.All in all those where the only two annoyances I seen with this tool, it’s kind of like a miniature version of the Power Probe which I also have. Can’t hardly wait to start using it!!
