Automotive Circuit Tester, 8–35V DC, TFT Display, 6m Cable

Automotive circuit tester helps you pinpoint wiring faults fast with a TFT color display that shows real-time waveforms and numeric readings. Designed for vehicle diagnostics across high and low voltage DC systems, it measures from -110V to +110V DC (not for household 220V circuits). A high-sensitivity probe, built-in work light, and long 19.7 ft/6 m lead make testing in bays, under dashes, and along frames easier.

Built for techs and serious DIYers, this power circuit probe tester streamlines troubleshooting on cars, trucks, and new energy vehicles without switching tools mid-job. Use it to verify polarity, trace power and ground issues, confirm continuity, and activate components for faster go/no-go decisions. The compact ABS housing is easy to store in a trunk or toolbox, ready whenever an intermittent fault shows up. Grab yours today and make electrical diagnostics more efficient.
