Everything you need to know about
Q: Does this tester support all types of automotive relays?
Q: Does this tester support all types of automotive relays?
A:It primarily targets the most common 12V automotive relays on the market, supporting both 4-pin and 5-pin specifications. As long as the pin layout conforms to standard automotive specifications, it can accurately identify and test them.
Q: I don't have professional repair experience, can I understand the test results?
Q: I don't have professional repair experience, can I understand the test results?
A:Absolutely no problem. Its logic is very intuitive: a green light indicates the relay is working properly; a red light indicates the coil or contacts are damaged. You only need to observe the color, without needing to read complex current data.
Q: Do I need to purchase an additional battery or connect a power cord for testing?
Q: Do I need to purchase an additional battery or connect a power cord for testing?
A:No. It is powered directly by the car's own 12V battery. The test clips use thickened alligator clips, simply clamping onto the positive and negative terminals of the battery to start working, making it very convenient for outdoor rescues.
Q: Why is the included pliers included in the kit?
Q: Why is the included pliers included in the kit?
A:The relays in a car fuse box are very tightly packed; removing them by hand can easily break the plastic casing or injure your fingers. The specialized extraction pliers feature a slender hook that easily reaches into crevices, applying even force to firmly pull the relay out.
Q: What should I do if the tester shows a red light?
Q: What should I do if the tester shows a red light?
A:If a red light is displayed, it means the relay has failed, which is the direct cause of your car's electrical malfunctions (such as a horn not working or headlights not turning on). It is recommended to immediately replace the relay with a new one of the correct model to restore vehicle functionality.
