Versatile Circuit Tester: Designed for 0–65 VDC systems, this automotive circuit tester works with all 8–35 DCV vehicle circuits. It supports testing polarity, continuity, signal circuit, component activation, poor ground, and short circuit tracking

Four Modes & 1.77 in TFT Screen: The power circuit probe tester features mode buttons for 4 diagnostic modes: DC voltage, AC voltage, resistance, and diode. The 1.77-inch TFT color screen displays values and waveform changes for real-time analysis

Component Activation Test: This probe tester can activate vehicle electrical components by outputting required signals, helping diagnose if parts such as headlights, window motors, radiator fans, wipers, and fuel injectors are working properly

Sensitive Probe & Overload Protection: This power circuit probe adopts a phosphor bronze probe for high conductivity and reliable testing. Built-in overload protection with an automatic breaker ensures your security and extends the tester's lifespan

Extended Cable & Flashlight: This short circuit finder comes with a 13 ft extended cable for long-distance reach. The built-in flashlight ensures clear visibility for efficient testing, even in dark or low-light environments
