3 Circuit Tester, Supplies Power & Ground (PP3CSRED)

Good tool to have and get at under dashboard locations. Takes a bit of learning to use this effectively for many tasks as I never had used one before but beats powering up components using a 12v battery.

Great probe. Perfect color. Great durability. Size is great, display is great.

Purchased this to replace an older model I've had for 20 years after the switch failed which was not serviceable. A good diagnostic tool.

I'm an avid automotive DIYer and I absolutely love this tool. It is a quality diagnostic tool that can be used for basic electrical problems. It supplies power and ground if you want it to. It also can check for power and ground. This tool has saved me lots of money on just one job. On my 2009 Civic, my rear door would not lock when I pressed the lock button. This tool helped me confirm that the lock actuator was broken. I removed the door panel and revealed the connector for the lock actuator. This tool helped me do two things: 1) Check for power and ground on the wires that feed the actuator and 2) provide power and ground to the actuator to see if it would engage. I found that the wiring was fine (power and ground were present) but when I provided the actuator with power and ground the lock did not engage. Dealers or shops would likely charge an hour's worth of labor for that job, and that's what this tool costs.

I haven't used it yet, but I already know how great these are. It works. Arrived in perfect shape. And I got a case for it for $12 from JB Tool Sales. Most pros already know about and have one except for some guys who, and I appreciate their passion and artistry, use incandescent test lights to charge solenoids and what not. This also makes sense for a DIYer maintaining their vehicle, because you can get pretty far with just this tool. It has a volt meter built in, a test light, and you can even power components during diagnosis. Just be careful, take your time, watch some YouTube videos, and you'll get good at it quickly. In part because this guy will make things much easier. Nice long dual clamp ended cord. You can leave the clamps on the battery. You don't have to go around looking for ground. It has a built in circuit breaker to protect it from overloading. It has distinctive sounds and lights to reveal issues. It has a separate alligator clip if you want to use it like a straight test light. Just very versatile. At $60, it really is a deal. Many people have paid much more for it, and have no regrets!

This tool is much reviewed on the internet - seems usually by people/techs that have never taken it out of their tool box. It most certainly is useful but I think more for the ability to activate/test components. A lot to remember in the instructions and so if you're like me, an occasional DIY user, you'll need to actually take it out and use it while reading the instructions to properly access it's usefulness. I seem to have survived without it for 50 years, but I always like buying tools. The four stars is just because I can't fully address the practical uses yet. Four stars for easy to use is because I think I'll need a couple of lead accessories to compensate for thickness of test tip. Three stars for accuracy is because I can't compare it to anything yet, although the voltage reading is the same as my Extech DMM. Whatever you do, understand the electrical circuit before activating the power button or you'll fry something. I think a double safety on switch would help prevent to hasty a decision to power the circuit.

Should have bought one of these long ago! Great product, makes diagnosing electrical issues so much easier.

Excelente producto para el automotriz ayuda a facilitar la prueba de componentes

No soy exactamente Mecanico automotriz, soy ingeniero en mecatronica, reparo equipo médico y quería una herramienta útil, compacta como mero hobby y que a su vez pudiera utilizarla en electrónica, habiendo visto la modalidad pico a pico de la cual casi nadie habla supuse que tenía la capacidad de encontrar una señal analógica como la de un transmisor de señal, ya no habría necesidad de comprar el ECT-3000 que es bastante caro. Con cualquier transmisor de esteren, fluke, o el que sea, se logra rastrear un cable. Leí las características de todos los modelos y este “básico” cubre lo necesario y lo cubre a la perfección. Quien necesite ver señales en can bus, definitivamente se usa un Osciloscopio. No este tipo de probadores. Superó con creces las dudas que tenía con este pequeño gigante. Feliz con la adquisición 👍

Previously had a PP4 which unfortunately failed outside the warranty so purchased this as a replacement. Handy tool for fault finding. Easy to use and has a long lead to hook up to battery and use the length of the vehicle your working on. Definitely a lot more basic than a PP4 but still a very useful capable tool.

Se siente de buena calidad el único detalle es que no tiene osciloscopio como otros en el mercado

12V電装屋さん必見！ 便利です。 信号がわかりやすく音と光で教えてくれて、電気をテスターから流すことも可能！

My go to for electrical diag work. So easy to use. Confirm circuit integrity, continuity, add power or ground. I like that the tip is removable and accepts any DVOM lead. This is my second one, I have one at home and one for work
