Power Circuit Probe Kit, P100 Car Circuit Tester, 12V 24V Automotive Electrical Tool, 6-30V Vehicle Short Circuit Finder with 40ft Cable, Trailer Truck Voltage Current Detector

Great customer service. I had one burn out, had a new one the next day. This machine has helped me save customers a lot of money. I can diagnose sensors and find shorts, test Fuses and wiring with precision. I was even able to simulate voltage for the temp sensor to verify cooling fans worked properly. Very nice setup. I also tried testing injectors. It does work but its a little more involved.

I was totally shocked and surprised that this Probe had a little "Lab Scope". Using A/C Voltage screen, I got the 'Scope' and Frequency and Duty cycle. It was able to 'see' my ignition coil primary firing! I would not be making a lab scope diagnosis from here, but, this is great for that first 15 minute view into 'What is going on here'? I am looking forward to proving it can 'See' things like Purge valve duty cycle, along with blower motors, fans etc!The other Probe features appear to be very good and normal. Positive and negative tip, circuit breaker, logic probe indicator, continuity, tone, Ohms, etc.Remember,TRIGGER CONTROL! Don't put power or ground to any computer circuit. Those are the really small wires. If you do, you will surely burn up the computer,.... you know....'Let the smoke out'!It is safest to disconnect the particular load from the circuit before trying to power it up and see if it runs, ie: UNPLUG IT!Happy Trails,

Very satisfied with this product, works as described and is very helpful with any wire testing! Plus it picks up on signal wavelength and that’s such a sweet feature. Don't hesitate and get it!

Great value! I use it all the time!

Great little tool for the price.Only 3 things I would change.1. Needs more tip options. The only one they give is pretty big and long which brings me to #2. The bag/box they give you doesn't allow for it to be stored without removing the tip every time which is very annoying.3. Instead of a cigarette lighter adapter a obd2 plug adapter would be better in my opinion since most newer vehicles don't have them any more.All in all for the price its a VERY nice unit.

Absolutely cannot recommend this tool enough. It works exactly as I hoped and has loads of features. Wasn't too hard to figure out. Plenty of cable length so no fear of it being annoying to use.The ground cable is a little short so make sure you've got some testing probes and wires for adjustments.Was chasing a No fuel pump No start condition that was hiding for days. Eventually found the culprit hidden in the Fuel pump assembly that holds the fuel pump together and allows the chassis harness to plug into it. Had a hidden arc damage in the connector on the assembly. This tool ruled it out by simulating power to the pumps making sure they were good but also fully testing the assembly to see if it worked.Solved the mystery and saved me a major headache. Would highly recommend this as it made my life so much easier.Yes it did come with a case too!The P150 model Fuel Pump testing worked flawless and was able to monitor Voltage as well.

I was not sure what I would get when I purchased this product but it has been very useful testing circuits on my vehicle, on my boat and even on my 48v golf cart. I have told so many people to buy this thing.

I recommend this over the PowerProbe. Comes with enough wire to go around a vehicle twice. Very durable and even measures OHMs.
