KZYEE KM50 (Upgrade of KM10) Power Circuit Probe Kit - 12V/24V Automotive Circuit Tester Current Probe with AC/DC Voltage/Resistance/Diode/Frequency/Duty Cycle/Fuel Injection, Activate Component

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.

Easy & quick transaction.Thank youLRZ-POZ

So far excellent tool, I was able to test my a/c fan in a minute and found out the fan was the problem. Don't need to be a mechanic to buy it, I really recommend it

i dont like the fact that no attachments were provided to get inside fuse box pins for relay testing etc. - the tip on this is too thick for a lot of the work this is meant for, like backprobing connectors - you can kind of jerry-rig needle multimeter attachments on top of it but its not great

This off brand power probe is fantastic! I Work in a shop with 4 other techs . Them having power probe branded and a snap on branded electrical testers and stand by them . But the cost of over $150 for a power probe brand and over $300 for the snap on branded testers was a bit much to choke down for a tool I use maybe 2-3 times every few weeks . So thought I’d give this one a shot and I’m not disappointed in my decision. Life is expensive enough don’t put your self in debt on a tool truck buy this and stay off that tool truck not about that $50 dollars a week for the rest of your life !

I was a complete novice when it comes to electrical testing, but the clear instructions and easy to use device made it easy for me to diagnose what worked and what did not in my vintage vehicle. The built-in circuit breaker made it easy to accurately test grounds and it was easy to find working and non-working circuits. Saved me THOUSANDS in mechanic costs because I was able to fix my car myself. INDISPENSABLE TOOL!!

Item did not disappoint, did everything I needed and more

Screen lights up but is always blank, either circuits bad or screen it, but it's doa right out of the box, literally the first time I used it, the same day it arrived. Should not have bought a cheap clone.Next day, I was going to use the non digital parts to chase down my issue, and it started working and I liked it.Since that one was flaky, I got another to try, seems to work, bumping 3 to 3 stars, will update next time I use it, but it's pretty infrequent, that I chase the kind of electrical issue that needs more than just a test light so it might be a while.They did refund the price with no complaints, so that's good. Liked customer serviceIf it seems reliable I'll update the review later.

I’m a professional mechanic and have used power probe products for the past 15 years and was happy with them until the power probe 4, constant problems, then failed. I purchased this one in hopes it would do well with electrical troubleshooting and it has. It works excellent, is accurate, well built, and cost effective.

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

PackagingThe 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 LookLooking 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 useThe 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 settingsDC Voltage, AC Voltage, Resistance and DiodeJust 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 circuitThe AC Voltage does the same but for AC VoltageThe 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 diodeI 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.

Das Gerät kommt in einem Plastikkoffer, was sehr praktisch ist.Im Lieferumfang sind:- der Tester selbst,- die Messspitze, die in dem Gerät verstaut wird,- ein Verlängerungskabel,- zwei Kabel für Stromversorgung des Gerätes: eins ist für Zigarettenanzünder und das zweite mit Klemmen ist für Anschließen direkt an die Batterie,- eine englische Anleitung.Alle Teile sind gut verarbeitet und sind aus robusten Materialien hergestellt.Das Gerät dient zum Überprüfen der Spannung des Bordnetzes, Messung der Widerstände, Prüfung der Dioden und für die Suche des Spannungslecks (Voltage Drops).

Good price, works as well as more expensive products
