It's ideal for automotive repair shops and home garage use alike.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this power probe detect both AC and DC voltage?\u003c\/h4\u003e\n\u003cp\u003eA: This tool is primarily designed for DC automotive circuits (5V–30V), which covers virtually all standard car and truck electrical systems including batteries, lighting circuits, sensors, and ignition systems.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the ghost voltage detection feature work?\u003c\/h4\u003e\n\u003cp\u003eA: When the probe is placed on a circuit, the LED display brightness indicates the quality of the voltage. A bright, steady reading indicates a genuine live voltage. A dim or flickering reading indicates a ghost (phantom) voltage — a residual charge that may mislead standard testers but is clearly differentiated with this tool.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the voltage tester pen come with a ground clip?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
