What is GODIAG GT101?

GODIAG GT101 PIRT Power Probe is a multi-use circuit tester with built-in diagnostic power. It is the best electrical tester for reducing diagnostic time in all 6to 40-volt vehicle electrical systems. Undoubtedly it is the most versatile and practical tool ever for its users.

This tool simplifies the testing of fuse boxes, verifies the correct operation of motors, lights, relays, sensors, wires, and communication circuits. The large digital color display makes for easy viewing in direct sunlight or complete darkness. 

Highlights for GODIAG GT101:

1. 4-in-1 Multi-function Power Probe: GODIAG GT101 4-in-1 PIRT is a newly released power probe by the GODIAG brand. It supports circuit breaker finder, fuel injector cleaning and testing, relay tester, and current detection function all in one device. The whole device weighs only 2.5lb – lightweight and easy to carry. Working voltage range 6V-40V, supporting a variety of vehicles. With GT101, you are all set!

2. Circuit Tester with 3 LED Indicator Lights: GODIAG GT101 circuit breaker finder can be used to diagnose an open circuit, short circuit, detect positive and negative circuit, and pulse current of power lines. When the vehicle's headlights, turn signals, lift windows, sunroofs and other functions fail, GT101 can be used to detect the circuit voltage or supply power for these components to find out whether it is a circuit problem or a component damage.

3. Fuel Injector Cleaning, Testing and Relay Test Function: GODIAG GT101 covers the detection of fuel injectors and relays, as well as the cleaning of fuel injectors. When the vehicle has difficulty starting, acceleration issues, and increased fuel consumption, it is necessary to check the fuel injector. When the car's headlights, turn signals, horn, and engine starter do not work, and there is no problem with these components after detection, you can check the relay switch.

4. 20ft Extension Cable & Flashlight: GODIAG GT101 PIRT power probe contains a 20ft / 242-inch long cable, which provides excellent accessibility to test along large vehicles such as trucks, buses, engineering vehicles, vessels, tractors, mining vehicles, and other vehicles that use DC circuits. Moreover, it has a built-in flashlight that will illuminate your work area even at night.

5. Overload Protection: GT101 PIRT has a built-in 10 amp circuit breaker to prevent overloading and cooking a circuit. The output current can be reversed to form a loop power, and when the current exceeds 20A, GT101 will automatically trip to protect the device and extend the service life. 

Main Functions of GODIAG GT101 PIRT Power Circuit Probe:

1. Circuit Troubleshooting Test (Short Circuit, Open Circuit)

When the vehicle's headlights, turn signals, lift windows, sunroofs and other functions fail, GT101 can be used to detect the circuit voltage or supply power for these components to find out whether it is a circuit problem or a component damage.

1) According to the circuit diagram, locate the fault point that may have the problem, and the GT101 electric tester can detect the positive and negative electricity.

2) Detect whether the circuit has normal positive or negative electricity.

3) Input positive voltage to the malfunctioning component (for example, a headlight or motor). If the component works normally, it means that the circuit may be open. Otherwise, it means that the component is damaged.

2. Relay Test

When the car's headlights, turn signals, horn, and engine starter do not work, if there is no problem with these components after detection, you can check the relay switch. After the relay is removed from the car, connect the adapter based on the connection of the relay.

3. Fuel Injector Test

When the vehicle has difficulty starting, acceleration issues, and increased fuel consumption, it is necessary to check the fuel injector. When detecting the fuel injector, if the fuel injector is driven to open or close, the ammeter shows the normal value and the fuel injector works normally, it means that the fuel injector is normal. Otherwise, it means that the fuel injector is damaged.

 4. Fuel Injector Cleaning

When the fuel injector is blocked, the fuel injection is not smooth. There are carbon deposits and thick sticky substance in the gap of the fuel injector. The designed fuel injection volume or atomization effect cannot be achieved – it needs to be cleaned.

1) Prepare a fuel injector cleaner pressurized can or a carburetor cleaner pressurized can (nozzle diameter of the pressurized cans: 4mm).

2) Hold the manual cleaning tool tightly with your hand, and firmly fix the fuel injector with your fingers to prevent the pressure of the cleaner can from washing away the fuel injector.

3) Pay attention to the hazards of liquid to the human body during manual cleaning, and take protective measures. Do not operate in dangerous places with open flames because the pressurized cans are extremely flammable. Choose an open place to facilitate the discharge of cleaning liquid.

 5. Used with the Wire Piercing Probe

1) First, turn the red knob and pull down the spring clip to an appropriate position, so that the spring clip can clamp the line under test.

2) Screw the red knob again to make sure the probe and the line under test are in good contact.

3) Insert the banana plug cable at the end of it (GT103 does not have a voltage and current display, and you can read the voltage of the line under test with a multimeter).

4) Plug the other end of the banana plug cable into the GT101 (also can be used with GT102 or GT103).
