1995 eagle talon replaced alternator and it boiled the battery what causes this?

Several factors can cause a freshly replaced alternator to boil the battery in a 1995 Eagle Talon:

1. Incorrect Alternator Installation: Improper installation of the alternator can lead to issues with its functionality. Ensure the alternator is securely mounted and all electrical connections are properly made and tightened.

2. Voltage Regulator Failure: The voltage regulator is responsible for controlling the alternator's output voltage. A faulty voltage regulator can cause the alternator to overcharge the battery, leading to boiling.

3. Battery Issues: A weak or damaged battery can also contribute to the problem. Ensure the battery is in good condition and has enough capacity to handle the electrical load of the vehicle.

4. Wiring Problems: Faulty wiring or loose connections in the charging system can cause voltage spikes or disruptions, leading to battery boiling. Inspect the wiring for any damage or corrosion.

5. Grounding Issues: Improper grounding of the alternator or other components can cause current to flow through unintended paths, leading to overheating and potential battery boiling. Ensure all grounding connections are clean and secure.

6. Overloading the Electrical System: If the electrical system is overloaded with additional accessories or modifications, it can exceed the alternator's capacity, causing it to overwork and boil the battery.

To resolve the issue, it is recommended to have a professional mechanic inspect the charging system and diagnose the exact cause of the problem. They can properly identify and rectify the underlying issue to prevent further damage to the electrical components and ensure the vehicle operates safely.
