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.
