Multi-Functional Auto Electrical Circuit Tester with LCD Display and LED Flashlight -- tests contin

Since I watched one youtube cast on car repair I wanted to buy Power Probe III Eric the Car Guy used. In my opinion original Power Probe is extremely overpriced. I hesitated buying this one being afraid it's low quality chinese cnock-off. This tool here I don't know about the legal issues patents and so, has exactly same functionality (and bit more) at lower price, extremely well made, is aesthetically and ergonomically nicer than power probe (I think whoever designed the shape and look of power probes was thinking about brick on the stick).

I totally love this tester here. Backlit LCD, white LED at the end to see what you're probing, extender for the probe and power supply, soft cable, good grip. low current test light safe for electronics.

You have two LEDs, red and green. red one goes on when you touch +12 or the flying lead of something connected to +12.

Green one goes on when you touch the ground or flying lead something that connected to the ground.

Using rocker switch you can supply the probe end with +12 or ground. This way you can test activate different circuits.

Warning! You should know and understand what are you powering and understand how electricity works. Otherwise you seriously risk frying something. In experienced hands this tool is awesome, you don't need a mess of jumper wires to test circuits anymore.

Tool has built in 5amp self reset breaker when you power the circuit.

I can't comment on the misfire detection function, my cars are in perfect shape here. Frequency/rpm meter can't see where I might need it in the car, we don't adjust idle anymore but let it be. with the voltage threshold detection for example you might check for voltage ripple in case of the bad generator if you understand it again.

Bottom line five stars from me

The device is just what I expected, it is practical and reading of the screen is clearly visible, the length of the cable allows testing in the rear of the vehicle as the rear lights and fuel pump built light lets you see just those parts dark in the back. You can test the pulse of the injectors without damage to the ECU. I think a good general test device Electics system of the car and easy to use. It is great device

I am a professional mechanic. This tool is good. The only downside that I have with this tool is that is doesn't make a beep sound when touching a B+ or ground like the power probe does. With that said, I think the other features in this tool make up for that over sight. The KV spark test function is cool. The jury is still out on weather the rated KV's shown on the tool are accurate, but it will quickly tell you if a car has spark or not (only cars with wires, not cars with coils on plugs). If you in the market for a power probe you should really take a good look at this tool. I would consider this tool a bargain at double the price!
