Where is the starter relay located in the BYD F3?

BYD F3's starter relay is located inside the interior trim panel in front of the driver's seat. The starter relay is a specialized component for compressor starting in single-phase asynchronous motors, functioning as an independent unit to connect and disconnect the attraction coil and holding coil circuits. The BYD F3 is an A+ class passenger vehicle produced by BYD Auto, with body dimensions measuring 4533mm in length, 1705mm in width, and 1490mm in height. The interior design of the BYD F3 features a simple and elegant style, with light-colored upholstery creating a fresh ambiance. It comes fully equipped, with higher-end models including leather seats, reverse parking sensors, and more.

In the BYD F3, the starter relay is typically located in the engine compartment's fuse box. Open the hood, and you'll find a black or gray box near the battery or the firewall side of the cabin. The relay is one of those small pin components, possibly labeled as 'starter relay.' If the relay is faulty, the car won't start or will only make a clicking sound when attempting to start. I recommend disconnecting the negative battery terminal first to ensure safety, then using a multimeter to test if there's current passing through. Replacing it yourself is simple—buy an original part for just a few dozen yuan, but the location might be hidden, so check the owner's manual or take photos to note the original position. Regular maintenance checks can prevent issues, such as aging relay contacts, which are a common problem.

I've just figured this out! The starter relay for the BYD F3 is usually located in the fuse box on the left side of the engine compartment. That box is positioned near the driver's side, and you can see a row of relays when you open the cover. If there's no response when you start the car, the relay might be faulty. Remembering its location makes repairs easier—I've replaced two this way. Spare parts are affordable at auto parts stores, costing around 50 yuan or less. When installing, make sure the plug direction is correct. Don’t forget to check the fuse and battery to avoid misdiagnosis. If your car starts slowly during normal driving, stay alert and address the issue promptly to avoid major repairs.

Experience tells me that the BYD F3 starter relay is located in the fuse box in the engine compartment. Specifically, open the box in the left front corner, and the relay is plugged in there. If you experience difficulty starting or no response, check here first. The location is not hard to find, but make sure to turn off the engine and disconnect the battery before working on it.
