How to tell if it’s a battery or alternator issue
Are you having trouble getting your vehicle to start? Most problems with starting are caused by either a dead or dying battery, or a defective alternator. The most common symptoms of a battery problem are:
- There is no sound or light when you attempt to start your car
- When you turn the key in, the ignition makes a clicking sound
- A slow-moving engine
- Weaker headlights
- Backfiring
- To start the car, you will need to press the gas pedal.
Jump-starting your car is a good idea if your battery seems to be dying or dead. If your car does not start , it is likely that the battery is to blame. To determine how old your battery is and if it needs to be replaced, you should have it tested.
If your car doesn’t respond to a jump-start, or you don’t have these symptoms, then it is possible that your problems are caused by a bad alterator. An indicator of a bad alternator is:
- Problems with your car’s electronics?
- After it starts, a car that stops after it has started
- Whining sounds from under the hood
- Burning smells
- Flickering headlights
- The alternator warning lamp turns on
If your vehicle isn’t starting or stopping after you jump-start it, your alternator may be failing to charge your battery. To ensure that the problem doesn’t get worse, it is best to have your alternator checked.
The battery warning light on your dashboard may not be lit up. This does not necessarily mean your battery is at fault. The warning light could also be a sign that your vehicle’s electrical system is not working properly. The battery warning light will go on if the voltage of your alternator drops below its maximum capacity.
The car’s battery stores an electric charge which allows it to start. The alternator transmits electrical current to your car’s battery, which allows it to charge even when it is not running. This electricity not only starts your car but also powers all electronics.
