Automotive Power Circuit Tester, TFT Display, 13 ft Cable

Automotive circuit tester probe helps you diagnose vehicle electrical faults faster with a TFT color display, component activation, and a long 13 ft cable for hard-to-reach circuits. Built for 8–35 DC power supply systems and testing up to 65 VDC, it checks polarity, continuity, poor ground, and short circuits while the screen shows real-time values and waveform changes for quicker decisions at the bay.

Keep one tester ready for rapid checks during installs, repairs, and no-start diagnostics. The high-conductivity probe supports stable contact, while the multi-mode power probe design helps you move from tracing a short circuit to verifying a ground or confirming component function without swapping tools. Ideal for garages, mobile mechanics, and DIY electrical work on cars, trucks, and 12V/24V systems. Grab yours today and streamline every electrical diagnosis.
