What Causes the Failure to Start When Jump-Starting the Battery?
1 Answers
Currently, the inability to start the vehicle when jump-starting the battery is mainly caused by two issues: 1. One is a rescue problem, where the jumper cables are too thin, resulting in insufficient current, improper operation during jump-starting leading to loose or poor connections, or the rescue vehicle not being started, causing insufficient voltage and current. This requires ensuring that the rescue vehicle has sufficient voltage and current and using compliant jumper cables for standard operation. 2. The other issue is with the vehicle being rescued itself. The battery of the rescued vehicle may have been depleted multiple times, unable to hold a charge and severely damaged, or the rescued vehicle may have other starting-related faults besides insufficient voltage and current, such as flooded spark plugs from failed attempts to start, or a faulty fuel pump preventing the vehicle from starting. In such cases, it is necessary to seek professional repair services for rescue and maintenance or to tow the vehicle to the appropriate repair facility for troubleshooting.
