Topdiag P100 Automotive Power Circuit Probe Tester, 12 24V Electrical Short/Open Breaker Finder, AC DC Diode Resistance Relay Tester, Continuity Test Digital Multimeter/Ohmmeters, 20 + 20FT Cable

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 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 ,

Great tool with out spending a lot of money in the original brand highly recommended

They wire is pretty short. If you just installing car radios you'll be alright but it won't reach to the rear of the car if the battery is up front. I ended up connecting a longer wire to it. I also took it apart and put some sticky wheel weights inside of if because it feel pretty light. Feels better in the hand but maybe that just personal preference.

Helped diagnose starter issue old vs new starter, new starter found defective thanks to this tool. Very accurate! Pretty easy to use.

Nice storage case, easy plug attachments, worked Great

Great for the price

I will like to buy again
