The GODIAG GT101 Power Circuit Probe Kit is a multi-purpose power circuit probe tester that diagnoses power from a car battery or an external battery. GT101 Car Power Tester is an electrical tester that reduces the diagnostic time for all 6 to 40-volt vehicle electrical systems. We have made video cases one by one, which will allow you to quickly and accurately grasp the various functional methods of the detection circuit. Why don't you act?
- Includes power injection, measurement, ground testing, polarity checking, continuity testing, and component activation.
- Easy-to-read volt-ammeter allows you to easily read voltage and current.
- By flipping the output switch, you can get positive and negative electricity through the probe to power electrical components such as cooling fans and relays. Use both the hot and ground wires to activate the components in your hand.
- Instantly identify positive, negative, open, and short circuits. Immediately test for poor ground contacts, allowing you to quickly trace and locate shorts without wasting fuses.
- Check the continuity of switches and relays immediately. Circuit breaker protection.
- Use a car battery or cigarette lighter to supply power. Built-in flashlight allows you to work in the dark.
- Audio Tone Indicator allows scrolling without looking at the menu once the user is familiar with the menu tone assignments.
- 20 feet (extendable with expandable cable port) cable provides excellent accessibility for testing along the vehicle.
- Extremely easy to use and high reliability. For DC 6-40v (working voltage) cars, motorcycles, trucks, buses, construction vehicles, ships, tractors, mining vehicles and other vehicles using DC circuits.
- Test all 0-80v electronic systems (probing voltage); Tip: Pay attention to the difference between working voltage and detection voltage.

Our versatile and user-friendly power circuit probe tester is designed to cater to everyone, from professional technicians to ordinary users. With easy-to-follow video tutorials and illustrated instructions, mastering its various operations is a breeze!

When the car headlights do not turn on, the window can not lift, the horn does not sound and other situations, you can use this circuit tester check what the problem is, so as to figure out whether it is a component problem or a problem with the car line.

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.

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.

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 use GT101 car voltage tester check the relay switch.

When the vehicle has difficulties in starting, acceleration, fuel consumption, etc., it is necessary to use an automotive injector tester to check the fuel injector.
When the fuel injector is blocked, the oil is not injected smoothly and the designed injection volume or atomization effect cannot be achieved, and cleaning is required.

Just choose the mode by pressing the mode button, and then contact the probe tip to a circuit, the LCD on the GT101 car battery tester will read the DC/AV voltage and resistance.

Compared to the test light that only displays DC voltage, the GT101 car circuit tester can also display AC voltage, resistance, and diode.

- Make sure the car engine must be turned off before using this device.
- Do NOT smoke or light near the car.
- Do not spill the car's fuel on hot engine parts.
- Perform this device in a well-ventilated place only .
- Do NOT approach any rotating parts of the car, and do NOT touch any heating parts of the car.
- Need a fuel jet cleaning agent aerosol cans (not included) and DC 12V DC battery power (not included), do not need compressed air.
