Frequently Asked Questions

Q: Do I need external batteries to run this tester?
A: No. The tool draws its power directly from your car's 12V or 24V battery using the included heavy-duty alligator clips.
Q: Will it tell me if my relay is short-circuited?
A: Yes. The tester monitors the contact resistance and coil health, alerting you immediately if the relay is stuck open, closed, or shorted.
Q: Can it test both 4-pin and 5-pin relays?
A: Absolutely! The interface is designed to accommodate both standard types, which cover over 90% of automotive relays on the market.
Q: Is it safe for my car's computer system?
A: Yes. It is an isolated testing tool that only draws power from the battery to test the disconnected relay, keeping your ECU safe from surges.
Q: How do I know if my car battery is too weak to test?
A: The device features a low-voltage warning light. If the battery is under 11V, the tester will alert you to charge the battery before testing.
