GODIAG GT101 Power Probe

GODIAG GT101 Power Probe is a multi-use circuit-tester with built-in diagnostic power. It can be used to diagnose an open circuit, short circuit, detect positive and negative circuit and pulse current of power lines; and support the testing of lighting lamp, window lift motor, horn, ECU control Unit power supply and other individual components, vehicle component circuit. It also covers the detection of relays and fuel injectors as well as cleaning of fuel injectors.

Suitable for All Vehicles: Whether you're working on cars, motorcycles, trucks, or even ships and tractors, our tester's DC 6-40v compatibility makes it the ideal solution for diagnosing electrical systems in any vehicle. The circuit tester features a reverse connection protection circuit, providing peace of mind during positive and negative line judgment. Plus, the built-in 10 amp circuit breaker ensures your equipment is safeguarded from excessive current.

Equipped with a digital colour display, reading voltage and current data is now a breeze. With a built-in flashlight and LED bi-color light makes for easy viewing in direct sunlight or complete darkness. The 20ft / 6.09m test cord grants excellent accessibility for testing around the vehicle.

Power Probe Key Features

• Performs every type of service including power injection, measurement, ground testing, polarity checks, continuity testing and components activation
• Easy-to-read volt-ammeter allows you to read voltage and current at your fingertips.

• Used for DC 6-40v cars, motorcycles, trucks, buses, engineering vehicles, vessels, tractors, mining vehicles and other vehicles that use DC circuits.

Easy to use

Our versatile and user-friendly power circuit probe tester is designed to cater to everyone, from professional technicians to DIY users. 

Relay Test

When the headlights, turn signals, horn and engine starter of the car do not work, if there is no problem in detecting these parts, you can check the relay switch.

Voltage & Polarity Test

When the vehicle can not start, in addition to checking locks, keys and other anti-theft system problems, you can also detect whether the battery voltage is normal.

Circuit Test

When a pulse signal with voltage is detected, the blue and red lights flash, the buzzer makes a rapid sound, and the voltmeter will display the voltage value of the current line.

OBD Voltage Test

When the scanners cannot identify the vehicle, we can use this probe to read whether the output voltage of the port is normal after eliminating the problem of the diagnostic interface.

Fuel Injector Test

When the vehicle has difficulties in starting, acceleration, fuel consumption, etc., it is necessary to check the fuel injector.

Fuel Injector Cleaning 

When the fuel injector is blocked, the fuel injection is not smooth, and the designed fuel injection amount or atomisation effect cannot be achieved, so it needs to be cleaned.
