Stop guessing with electrical failures. The LamiWexi Relay Tester automatically cycles and tests your vehicle's 4-pin and 5-pin relays, giving you an immediate, clear pass/fail result without complex multi-meter setup.
The LamiWexi Relay Tester features automatic 10-cycle testing checking action release timing and contact consistency. The bright green and red light indicators mean zero misinterpretation for you.
Skip the multiple tools. Equipped with dedicated sockets and a simple gear selector, it supports standard 4-pin and 5-pin automotive relays in cars, vans, and commercial trucks.
Monitor live battery voltage from 11V to 25V directly from the bright digital screen. This covers 12V cars and 24V trucks alike, providing simultaneous relay and battery diagnostics.
"The LamiWexi Relay Tester simplifies testing down to a single button press. Its 10-cycle automated test captures intermittent failures that single-cycle testers often miss, making it an indispensable tool for both DIYers and professional mechanics."
