What are the reasons for the electric starter motor not responding?
2 Answers
The reasons for the electric starter motor not responding include incorrect gear position, not pressing the brake pedal, or the steering wheel being locked. Below are relevant details about the battery: Lifespan: Generally, a car battery has a normal lifespan of about two years; Maintenance: With proper maintenance, it can be extended, and the best ones can last around four years. Signs of a car battery running out of power: The car is difficult to start after being parked for two days, and the car noticeably becomes heavier when driving with the air conditioning on. Notes on car batteries: Modern car batteries come with a protection function that reserves the minimum power required for starting. If you turn the key without igniting the engine and use accessories like the radio or lights, it can last for about an hour or so.
I've encountered this situation before where the car battery has power, all the dashboard lights are on, but nothing happens when you turn the key to start the engine. There could be several common reasons: First, the starter itself is faulty, with worn carbon brushes or a stuck electromagnetic switch inside, preventing engagement and rotation; Second, there's an electrical circuit issue, such as a blown fuse or a damaged relay—the relay is that small box controlling the current, which you can find in the fuse box, and you might try replacing it; Also, the battery cable terminals could be loose or corroded, preventing the large instantaneous current needed for starting from passing through, even though small electronics work; For automatic transmission models, if not in P or N gear, the safety switch will prevent starting, while manual transmission requires pressing the clutch pedal firmly; Even the ignition switch could be worn or the key's anti-theft system locked. I recommend starting with the simple checks: ensure the gear is correct, tighten the cables, and if that doesn't work, take it to a repair shop—never force-start it to avoid damaging other components. Regular maintenance, like cleaning dust from the terminals, can help reduce these hassles.
