What causes the Wuling Zhiguang's battery to have power but no response when starting?
3 Answers
There are several reasons why the Wuling Zhiguang's battery has power but no response when starting: 1. Possible starter motor damage: If there is no sound at all when turning the key, it may be due to a damaged starter motor, which needs to be re-engaged or push-started. It could also be an issue with the fuel pump, so please inspect carefully. 2. Poor or incorrect wiring connections: Poor grounding of the battery; damaged distributor or Hall sensor; faulty ignition switch or poor wiring connections; damaged transistor ignition control unit or poor wiring connections. Most diagnostic methods for low-voltage circuit faults involve using an ammeter or voltmeter to check each line and eliminate fault points. 3. Severe carbon buildup in the throttle: This can cause insufficient throttle opening, preventing the combustible mixture from entering the cylinder for combustion, resulting in failure to start.
The battery has power but there's no response when starting. I often encounter this situation with my Wuling Sunshine. The most likely cause is an issue with the ignition system. The most common problems are a faulty starter motor or a bad relay. The relay acts like a switch; if the contacts are burnt or the coil is faulty, the current won't reach the motor. Another issue is poor wiring connections, such as loose or corroded battery terminals, which prevent current from passing through—this is quite common in older cars. Another point is a blown fuse, especially the starter fuse, which can burn out with even a slight current surge, so you need to check the relevant fuses in the fuse box. If all these are normal, the ignition switch itself might be worn out and need replacement at a professional shop. Remember not to force it, to avoid damaging more components.
My Wuling Zhiguang had the same issue for a while - the battery was fine but it just wouldn't start. I think the key is to check two aspects: First, the starter motor - if it's rusted or the carbon brushes are worn out, it simply can't turn; Second, wiring issues, like poor contact in the cables from the battery to the motor, especially prone to loosening on bumpy roads. Another common culprit is the relay - that small component often fails as it operates in high temperatures. You can usually check the fuse box yourself and try replacing the fuse for the starting circuit. If that doesn't work, it's best not to tinker blindly - take it to a repair shop and let the mechanic test the circuit with a multimeter. After all, waiting for roadside assistance while stranded is quite dangerous.
