- Battery: Even though the battery is new, it may not be getting a proper charge from the alternator. Have the alternator tested to make sure it is functioning properly.
- Alternator: The alternator is responsible for charging the battery. If it is not working properly, the battery will not be able to hold a charge and will eventually die.
- Voltage regulator: The voltage regulator controls the amount of voltage that is sent to the battery from the alternator. If it is not working properly, the battery may be getting too much or too little voltage, which can damage it.
- Starter: The starter is responsible for turning over the engine. If it is not working properly, it will not be able to engage the flywheel and start the engine.
