I recently picked up the Power Circuit Probe Tester for my car projects, and I have to say, it works great! I've been installing car radios and alarms for a while now, and this tool has been a real lifesaver. It's straightforward to use and handles the 4-24V DC range perfectly.I wish I had it earlier; it saves so much time and frustration when checking connections and diagnosing issues. If you're someone who works on car electronics frequently, I’d say it's a must-have. Definitely worth the investment!

This Automotive circuit tester seems to work well and allows the user to probe live circuits or to apply voltage into a circuit. This circuit tester features battery clamps that will fit on a variety of battery terminals. With the battery clamps attached, the user can easily probe circuits. When the circuit tester probes a negative wire or terminal, the tester will display a green LED. When the circuit tester probes a positive wire or terminal, the tester will display a red LED. This circuit tester can also be used to apply a positive or negative voltage into a circuit by probing the circuit and operating the switch. After testing the circuit tester, I found that the tester seems to work well and functions as expected. The wide voltage range (4V – 24V DC) allows this circuit tester to be used on a wide range of circuits, not just automotive circuits. This circuit tester will be a handy tool for troubleshooting automotive electrical issues. It’s simple, easy to use, and a very effective tool.
