VDIAGTOOL V200 Electrical Testing Kit sku-3882201895

The Red VDIAGTOOL V200 is an Electrical Testing kit for 12V and 24V vehicle circuits. Its wire tracer is described as having a 40FT cable. A single button switches among 4 modes: DC voltage, AC voltage, resistance and diode testing. DC mode displays circuit voltage at 0.1-volt resolution; AC mode shows maximum and minimum voltage and frequency.

Resistance mode checks between the probe tip and auxiliary ground lead to identify complete or broken circuits and compare component resistance with the manufacturer's specification. Diode mode checks conduction and displays forward voltage when current flows.

The stated specifications are a DC voltage range of 0-65V, resistance range of 0-100 kΩ, rated current of 1-10 amps and sound-passage frequency response of 0Hz to 10 kHz. The probe identifies positive or negative ground circuits and displays volts, with a red light for positive and green for negative.

It has an automatic circuit breaker, short-circuit and overload protection, a built-in light and a 20 FT. extension cable; the source also describes a 20ft. extension cord for testing across a vehicle or in dark areas. In DC voltage mode, it can send activation signals to components such as lights, relays, fuel injectors and motors.

The probe can help locate a short by energizing fuse contacts and identifying the contact that trips the breaker. Resistance mode checks continuity on wires and components attached to or disconnected from the vehicle. For trailer lights, clip the auxiliary lead to trailer ground, probe the jack contacts and apply voltage to check connector orientation and light operation.

A suspected ground that trips the breaker is likely a good ground. For a self-test, press the switch forward: the tip activates positively, the red LED lights and battery voltage appears. Press it backward to activate the tip negatively; the green LED lights and the display reads 0.0V. SKU: sku-3882201895. UPC: 789605297267.
