WUQ KM10 Power Circuit Probe Kit 12V 24V 40FT Cable

Automotive Circuit Tester Kit

The WUQ KM10 Power Circuit Probe Kit is a professional automotive diagnostic tool designed for 12V and 24V vehicle electrical systems. It combines DC/AC voltage measurement, resistance testing, diode checks, and component activation in a single handheld unit. The 40FT cable reach suits trucks, RVs, and buses, while dual power options allow connection via battery clips or cigarette lighter. A built-in flashlight and buzzer assist work in dark or noisy environments.

Technicians and Fleet Mechanics

This kit suits automotive technicians, fleet mechanics, and serious DIYers who need to trace shorts, verify grounds, and activate components such as fans, pumps, relays, and motors without removing them. The one-tap mode switching and clear LED polarity indicators speed up fault finding on heavy-duty and passenger vehicles alike. It is not for users who only require a basic test light for simple continuity checks, nor for bench electronics work below 12V.

630V Maximum Voltage Rating

The single specification that decides fitment is the 630V maximum voltage rating across the four test modes. This defines the safe operating window for all voltage, resistance, diode, and activation functions on 12V and 24V systems. Exceeding this limit risks instrument damage and user injury, so confirm your application stays within the rated range before purchase.
