Multi-Functional Auto Electrical Circuit Tester with LCD Display and LED Flashlight - tests continuity, polarity, voltage, frequency, misfires

Diagnose a variety of common automotive electrical problems with your car's shop manual and this circuit tester kit.

To power up the tester, simply connect it to your car's battery or cigarette lighter socket. Then the tester can be used in four modes - voltmeter, misfire locator, frequency meter, and threshold detector. It can also perform simpler tests like continuity, polarity, and energizing individual components such as lights, fans, and fuel pumps to check their operation.

The carrying case organizes and protects the entire kit. Keep it next to your shop manual and wrenches for routine check-ups and maintenance. And if you're a weekend warrior, maybe bring it to your races to help out with track-side troubleshooting!
