    no, if you have the right alternator on you should be fine. make sure the one you have is the right one

    Yes it is. There are 2 ways to fix it. If you have a external Voltage regulator you can replace it. If that's not the problem replace the alternator. If you have a alternator with a internal Voltage regulator you can have the alternator rebuilt or replaced. Normaol voltage output should be 13.6 volts to 14.2 volts. If it is higher than 14.2 volts you have a problem. Don't let it go. You can possibly blow up the battery or catch the car on fire due to overheated wiring. I've tested some that were 15.7 to 16 volts and had to repair or replace the alternator.

    yes you will cook the battery and runin it usually the altnator has a built in voltage regulator in it and might be sticking to put out more volts! also check do you have a guage on the dash or a lite some times the guage goes bad. but a rebuilt altinator is not a lot of money depends on the car

    Yes, you could "overcharge" the battery, and with some older batteries, produce enough hydrogen that would seep out of the battery and catch on fire.

    In general, most car electrical systems have "regulators" that will limit the overcharge, so either the regulator itself is dead or the alternator itself is on the fritz. An electrical test should tell you which is which (those battery checkers used by road service should do) and you will replace the appropriate part.

    Yes, your alternator can over charge the battery and "cook" it, it will start boiling. The culprit is a bad internal regulator. A regulator is basically 3 diodes. They regulate the voltage so it doesnt go avove 12-15 volts. I rebuilt my alternator in my camaro years ago, all I needed to replace was the brushed, brush springs and the regulator diode. It worked like a champ after that!

    Actually, ALL alternators provide too much power. That's where the voltage regulator takes over. You want an alternator to provide more power than needed (so it will provide plenty of charge), and the regulator SHOULD take care of the excess.

    Yes it is possible. If it sends to much power to the battery, the battery could catch on fire. You would have to the alternator to a shop and have them test the output.

  • No, the battery takes as much power as it can from the altinator and then the altinator swicthes itself off.

    Maybe you have a problem eslewhere with your car?
