What Causes All Warning Lights to Illuminate and the Car to Fail to Start?
1 Answers
When all warning lights illuminate and the car fails to start, the most common cause is insufficient battery charge. Below are key points regarding the battery: 1. Low Car Battery Voltage: Use a multimeter to test the battery voltage. If it reads below 10V, replacement is recommended. If around 11V, it may still function temporarily, but prepare for replacement. A reading above 12V indicates normal operation. 2. Service Life: Car batteries typically require replacement every 2-4 years. Theoretically, a car battery's lifespan is generally 2-3 years, but with proper use and maintenance, it can last up to 4 years without issues.
