RelayCheck Pro delivers instant relay health checks by drawing power from a 12V battery and presenting a clear LED result that tells you if the relay is functioning.
It tests standard automotive relays by wiring directly to a 12V battery within 11–15V and supports most relays with coil resistance above 20 ohms.
Green LED indicates the relay is functioning, while a red LED signals a deviation or fault.
Designed for easy operation, simply connect the battery, insert the relay, and press the button to reveal the result instantly.
The device is housed in a durable ABS plastic shell and is compact and portable for use in the workshop or on the go.
Key specifications include a 12V power supply (11–15V), a LED display with Green = Function check passed and Red = Deviation detected, compatibility with standard automotive relays that meet the coil resistance criterion, and a sturdy, portable form factor.
Included in the package are 1× Automotive Relay Tester and 1× Instruction Manual.
