Quick Relay Diagnosis for 12 V Systems

The Performance Tool 3009 checks 12-volt four-pin and five-pin automotive relays outside the vehicle. It tests coil and switch contact function with a self-contained, battery-powered design. Green and red LEDs give instant pass or fail indication. Mechanics and DIY owners can verify relay health without clamping to the battery.

Steady LED Indication During Extended Testing

The tester maintains clear green pass or red fail signals throughout repeated checks. Its all-in-one housing stays powered by the included AA batteries for consistent operation. No external connections are required, so results remain stable across multiple relays. The compact unit weighs 0.281 kilograms for easy handling.

Verify Relay Pin Count and Voltage Before Use

Confirm the relay is a 12-volt type with either four or five pins; other configurations are not supported. Ensure the tester’s battery compartment holds fresh AA cells for reliable LED readouts. The tool is designed for bench or in-bay use, not for in-circuit testing while the vehicle is running.

Questions about this item

How much battery power does the 3009 relay tester draw when I leave it connected during a full day of diagnostics?

The tester runs on included AA batteries and only activates its green or red LED during the brief moment you press the test button, so there is no continuous drain while it sits idle.

What do I need to have on hand before the 3009 can test a 12-volt 4-pin or 5-pin relay?

Nothing beyond the tester itself and the AA batteries already supplied; it requires no external clamps, cables or vehicle battery connection.

Will the 3009 work on the older 12-volt relays I keep in my classic-car spares box?

Yes — it checks the coil and switch contacts on most common 12-volt 4-pin and 5-pin automotive relays regardless of vehicle age.
