VDIAGTOOL V200 Automotive Circuit Probe Tester, 12V 24V Car Power Circuit Probe Kit, AC Voltage, DC Voltage, Diode Test, Resistance Check, Electrical System Test Tool, Power Circuit Tester

All worked good. Only issue I would say have to be mindful when connected the cables when use the extension cable.

I tried out the VDIAGTOOL V200 Automotive Circuit Probe Tester on my car, and it worked really well. It made figuring out electrical problems a lot easier. I felt safe using it because it has features to protect against overloading. Plus, the long cord made it simple to reach all the parts of my car. Overall, it's a great tool that anyone can use to fix car electrical issues.

First job I used it on was to test in-tank fuel pumps - worked a treat and established pumps were unserviceable - great bit of kit!

This is my first time using a tool like this. Been using it for the past month now on several vehicles. Checks voltage/amperage like a multi meter but can also apply power to actuate components that need battery power. Great for troubleshooting. A tool that saves a lot of time. Ive been able to trouble shoot faulty fuel pumps, window motors, power seats and door locks. However i dont think it can be used on high amperage circuits like a starter. I havent tried powering a starter but dont think it was designed to apply high current. Wish I had this tool when I worked at a shop. No longer work at a shop but still work on a lot of friends and family vehicles. Highly recommended.

I used this to diagnose which terminal was bad on a Pentastar 3.6. I could have used the old probe light but I needed to know if there was 5 volts at the terminal. A definite “need” if you’re working on newer cars with all those wires.
