It’s Difficult to Start Your Car
Your mind probably goes to two things when you’re unable to start your car: either you’re out of fuel or you have a dead battery. It can also point to a failing alternator, which helps transfer power to the battery, spark plugs, and other systems. If your spark plugs can’t get power, your engine won’t be able to start. It’s best not to ignore this problem, no matter what the cause ends up being. Eventually, your car just won’t start at all.
You Could Also Find Your Car Stalling
Similarly, you may notice your car stalling if your alternator is failing. This is also because of a lack of power being transferred to your spark plugs, so even if your engine is running, they may lose the ability to ignite the fuel-air mixture that keeps the engine running. A stalling car should be addressed as soon as possible by a trusted mechanic.
