Automotive Power Circuit Probe Tester - DC 6V to 40V Electrical System Diagnostic Tool

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

The GODIAG Electric Circuit Tester boasts a range of key features that make it a valuable tool for various automotive diagnostics and maintenance tasks. It can perform every type of service, including power injection, measurement, ground testing, polarity checks, continuity testing, and component activation. The easy-to-read volt-ammeter allows you to quickly read voltage and current. By flipping the output switch, you can access positive and negative electricity via the probe, powering up electrical components like cooling fans, relays, and more. The simultaneous use of the hot lead and ground lead enables you to activate components right in your hand.

This circuit tester instantly identifies positive, negative, and open circuits, while also testing for bad ground contacts, allowing you to quickly locate and follow shorts without wasting fuses. It also checks the continuity of switches and relays. The circuit breaker protection ensures safety, and the built-in flashlight enables you to work in the dark. An audio tone indicator allows for no-look menu scrolling once users are familiar with the menu tone assignment.

With a 20-foot cable (extendable via the cable port), the GODIAG Power Circuit Probe Tester provides excellent accessibility for testing along the vehicle. This extremely easy-to-use and highly reliable tool is suitable for a wide range of vehicles, including DC 6-40V cars, motorcycles, trucks, buses, engineering vehicles, vessels, tractors, and mining vehicles.

The circuit tester is particularly useful in various troubleshooting scenarios. When the car headlights, windows, or horn are not functioning, you can use this tool to check the problem and determine whether it is a component or wiring issue. If the vehicle cannot start, in addition to checking locks, keys, and the anti-theft system, you can also detect whether the battery voltage is normal. When scanners cannot identify the vehicle, this probe can be used to read the output voltage of the diagnostic port, helping to eliminate the problem.

The GODIAG Power Circuit Probe Tester also allows for relay testing. When the headlights, turn signals, horn, or engine starter do not work, and no problem is detected in these parts, you can check the relay switch. Additionally, the fuel injector test and cleaning functions are invaluable when the vehicle has difficulties in starting, acceleration, or fuel consumption.

The package includes a variety of accessories, such as a clip to connect the battery, a probe, a probe cap, a fuel injector test lead, fuel injector cleaning connectors, a simple relay test adapter, and relay connection leads, as well as an English manual and a storage bag.
