The US PRO Automotive Relay Tester 6794 is designed for automotive technicians and DIY enthusiasts who need to quickly and accurately verify the functionality of common automotive relays. Its key benefit is providing clear, visual pass/fail indicators using LEDs, powered directly by the vehicle's 12V battery. A minor caveat is its focus on only three popular relay types, requiring alternative methods for less common relays.

The US PRO Automotive Relay Tester 6794 is designed to verify three of the most popular automotive relay types. Specific models may vary, so consult the product documentation for precise compatibility.
Connect the red lead to the positive (+) terminal of your vehicle's 12V battery and the black lead to the negative (-) terminal. Then, connect the tester to the relay you wish to test.
A red LED light signifies that the relay has failed the test and is likely abnormal or faulty.
A green LED light indicates that the relay has passed the test and is functioning normally.
No, the tester operates by drawing power directly from the vehicle's 12V battery.
No, this tester is designed for 12V DC systems only.
The tester is not waterproof. It should be kept dry and protected from moisture to prevent damage.
Ensure the vehicle's 12V battery is connected and has sufficient charge. Verify that the red and black leads are correctly connected to the battery's positive and negative terminals, respectively.
This indicates an abnormal relay function. The relay may be faulty, or there might be an issue with its internal wiring that the tester is detecting. Consider replacing the relay.
Check the relay's connection to the tester and ensure the tester is properly connected to the vehicle's battery. The relay might also be of a type not supported by the tester.
Ensure all connections are firm and secure. Battery voltage can fluctuate; try testing when the engine is off but the battery is stable. Ensure the relay is correctly oriented within the tester.
Setup: To set up the tester, connect the device's leads to the vehicle's 12V battery terminals, observing correct polarity (red to positive, black to negative). Then, connect the tester's appropriate terminals to the automotive relay you wish to test. Ensure a secure connection for accurate readings.
Compatibility: This tester is designed to work with a 12V DC power source, typically found in most standard passenger vehicles and light trucks. It is specifically compatible with three popular types of automotive relays; refer to the device's documentation for exact compatibility details.
Care: Keep the tester clean and dry. After use, disconnect it from the battery and relay. Store the device in a protected location, such as a toolbox, to prevent damage from impact or exposure to moisture. Avoid exposing the tester to extreme temperatures.
