Eliminate electrical guesswork with a precision tester that simulates real-world load conditions. Its automatic 10-cycle stress test delivers an instant pass or fail verdict for 12V relays.

Tests relays under real load
Automatic 10-cycle stress test
Instant Red/Green LED results
Works with 4 and 5 pin relays

Question 1: What types of automotive relays is this device compatible with?
Answer 1: This tester is designed for universal compatibility with standard automotive relays. It features a simple selector switch that allows you to easily test both 4-pin and 5-pin configurations, making it suitable for most cars, SUVs, and trucks.

Question 2: Does this tool require its own internal batteries to operate?
Answer 2: No, the device is battery-free. It draws power directly from your vehicle's 11V-15V battery by connecting via durable alligator clips, ensuring the tool is always ready to use without the worry of dead batteries.

Question 3: How do I interpret the results to know if a relay is bad?
Answer 3: The tool uses a simple, binary LED interface for clear diagnosis. After running an automatic 10-cycle stress test to simulate real-world load, a Green LED indicates the relay is functioning correctly, while a Red LED instantly alerts you to a failure.

Frequently Asked Questions

Find quick answers to the most common questions about our product.

It is designed to be universally compatible with most standard 12V vehicles. It features a selector switch to accommodate both 4-pin and 5-pin relays, which covers the vast majority of cars, SUVs, and trucks. As long as you have an 11V-15V battery, you are ready to test.

Absolutely. Unlike a multimeter that requires technical knowledge and steady hands, this tool offers a simple "plug and play" experience. Just connect the clips to your battery and plug in the relay. The intuitive Red/Green LED system gives you an instant, definitive answer without deciphering complex voltage readings.

No, you never have to worry about dead internal batteries. The device draws power directly from your vehicle’s 12V battery using durable alligator clips. This ensures the tester is always ready for action and simulates real-world conditions by putting the relay under an actual electrical load during testing.

Swapping parts gets expensive and doesn't always solve the root issue. This tool performs a 10-cycle "stress test" to catch intermittent failures that a simple swap or continuity test might miss. It detects sticky contacts and ensures the relay can handle rapid operation, saving you money on unnecessary parts.
