Car Relay Tester Conversion Plug For 12V/24V Testing, Automotive Maintenance

Meet the Car Relay Tester Conversion Plug — a versatile diagnostic tool designed for quick, reliable testing of 12V and 24V automotive relays, whether they have four or five pins. Built for car and motorcycle maintenance, this compact tester helps you verify relay operation at a glance, saving time on troubleshooting and ensuring your electrical systems are performing as intended.

With an upgraded high-definition LED display, you can read results clearly even in dim garages or under hood lighting. A bright illumination lamp activates with a single press, letting you work confidently in low-light conditions. Two high-capacity lithium batteries power the device, delivering long-lasting operation between charges, and the included charger ensures you're never out of power during repair sessions.

The tester's primary function is to determine the normal functioning of automotive relays. Its quick display analysis helps you distinguish good relays from faulty ones for both 12V and 24V applications, reducing guesswork and speeding up repairs.
