KZYEE KM10 Car Power Circuit Probe Kit, 12V 24V Automotive Circuit Tester, AC DC Diode Resistance,Component Activation,Short/Ground/Continuity/Trailer Test,20FT+20FT Cable

Packaging The tester came in a cardboard outer sleeve. Once removed you will find a hard-plastic case that holds the tester unit and the accessories. Upon opening the box you notice how well the unit is fitted in there with a nice thick foam insert in the lid. First Look Looking at the unit you see how well it looks and some of the nice design features it has with the colour screen and the removable probe along with a massive 20ft extension cable. It has all the connections you need, Direct from the battery or from the included lighter socket adapter. First use The unit was powered by the lighter socket and booted up into the menu in a second. You are presented with a nice clear colour display and 4 menu options at the top of the screen. The unit has 2 led's on the top of it giving you some light to work with. You select the menu option with the round menu button on the device. The menu runs through the following settings DC Voltage, AC Voltage, Resistance and Diode Just press the menu button until you see the correct screen. With the probe in DC Voltage it allows you to read the DC Voltage of a circuit The AC Voltage does the same but for AC Voltage The Resistance mode enables you to check the resistance between the tip and the Aux ground Lead. In this mode you can check the voltage drop from positive to negative on a diode I used the probe to check a few headlight bulbs I had lying around not knowing if they were out or not. I connected the Aux cable from the probe to the negative on the bulb and touched the tip to the positive, this allowed me to check the circuit. The screen went green confirming no issues with the continuity of the bulb I then pushed forward on the toggle switch and applied voltage to the bulb lighting it up. A quick two-minute task is completed with the tester saving a lot of time and effort. My Thoughts, All in all a solid bit of kit with easy to use features and a easy to use menu. A Good design aesthetic and all stored in hard plastic case. a must for anyone who works on electrical systems.

Love this tool! Really speeds up diagnosis.. love the fact that you can inject positive or negative feed down a wire by pressing a switch.. makes circuit detection instant! works on 12 or 24v so good on cars/vans and commercial HGV also. Nice set of adaptors, well made and sturdy.. dont wait, just buy it.. will pay for itself in saved hours probably on the first job or 2!

As an Automotive professional brought this to replace my original power probe, thought it would be useful to display the different voltage on vehicles as opposed to just + & - V. Used everyday for last 2 weeks on approx 10 jobs per day and has performed fine, has 2 LED's that come on as soon as powered up that at first I found annoying but have to admit are quite useful, easy to probe into looms (beeps let you know when contact made). Only point I would make is having been a tech for many years tool does feel a bit cheap and lightweight, as opposed to just chucking this back in toolbox when finished I keep it out of the box on the dashboard of my van, and so far all ok I wouldn't think it would last long rolling about with other tools in a drawer, on the positive side leads are good quality and with the extension cable you could easily walk around an artic cab and trailer.

So easy and simple to use I had a charging problem and had the RAC have a look and then a garage but I used the KZYEE KM10 Power Circuit Probe Kit and found the fault myself

Kept putting off buying one of these sticking with my old multi meter but the first day of receving this it made its money . great bit of kit would recomend to any one

This is a great product, my husband said it was absolutely the best gift I have ever got him. had a small problem and the customer support was fantastic! he would highly recommend this product and has to all his customers and colleges.

Good pice of kit

Fantastic piece of kit very durable and very easy to use would recommend to all

Funciona todo bien menos que no mide resistencias solo sirve para comprobar continuidad

Sensationell gutes Gerät für die Fehlersuche bei der Kfz Elektrik. Strom durch die Leitung schicken, Durchgabgsprüfung und Spannung auf + / - kann gemessen werden.

Great tool easy to use

Works good

I had used it for about a year, no major issues. My only issue with the design is the length of the grounding cable, just a bit short for what I usually need it for, but I've been able to make it work with an extra wire. The only real problem I came across was when I had made the mistake of trying to apply power or ground to a wire when it had the other already active. User error, really. But it was when I kept doing it when I had to apply one of the two before making contact, like in a tight space. It would normally shut down and restart if you made a mistake, like normal. But I had done it quite a few times in a row and it had shut down completely. Few days later, it starting working again, but sometimes when you power it, it doesn't show or do anything on the screen but a blank background. Again, user error caused it. But other than that, having it as a mobile mechanic has saved me so much time, being able to see what is actually happening. I only have the KM10, but I honestly might upgrade to see what I can use the nicer model for. It was well worth the price.
