Will a bad alternator boil your battery?
Short answer: yes Long Answer: A bad Voltage Regulator can allow an overcharge to the battery. Your charging system should be running around 14.2 to 14.8 volts DC with the car running. A bad voltage regulator may allow up to 18 Volts DC to run through your system. Not good for your battery. Some vehicles have a separate Voltage Regulator and some are part of the Alternator. There is also a part in the Alternator called a Diode Trio that changes the AC voltage that the alternator produces to DC Voltage that your car's electrical system uses. Batteries don't like to be fed AC voltage, it can evaporate the electrolyte fluid.
