Multi-function automotive tester

The GODIAG GT101 Power Circuit Probe Kit is a multi-purpose electrical tester for 6-40V vehicle systems. It combines voltage and current measurement with relay testing, circuit interruption and fuel injector cleaning. Technicians and DIY owners use it to diagnose power circuits from a car or external battery.

20ft cable with colour display

A single 20ft test cable connects the probe to the battery, giving reach around the engine bay and chassis. The built-in digital colour display shows live voltage and current readings without a separate meter. Integrated torch and bi-colour LED illuminate the probe tip for work in low light.

Polarity switching and component activation

Flipping the output switch supplies positive or negative voltage through the probe tip to power fans, relays and other components directly. Continuity checks on switches and relays are instant, while circuit-breaker protection prevents fuse waste during short-circuit hunts. The kit also performs ground testing and injector cleaning cycles.

Questions about this item

What does the 6-40V working range mean when testing a vehicle electrical system?

The probe operates on any DC system between 6 and 40 volts, so it covers motorcycles, cars, and light commercial vehicles without needing a separate adapter.

How does the 20ft cable change the way you use the probe around the vehicle?

The 20ft lead lets you reach from the battery or cigar-lighter socket to any corner of the engine bay or chassis without moving the power source.

What mounting or connection points does the kit need to start testing?

It connects directly to a 6-40V battery or cigar-lighter socket and uses the probe tip plus a ground lead to power or measure components in place.
