What electrical problem in a car can cause the stator of an alternator to be burned?

Question

Since I have bought my car i replaced my alternator three times. When i bought the car the alternator i believe was bad so i changed it. A stock one was put back in it. that failed and i thought it was because of my audio system. i replaced it again with a 200 amp alternator and I was told that the car burned up the stator. i have replaced it again and will be going to an electrician but if anyone know the problem that is causing this it could save me a lot of money from taking it somewhere and getting charged tons of money. By the way its a 88 Acura Legend.

Answer 1

It sounds to me like the voltage regulator is grounded out somewhere inbetween the alternator and the computer and when you get a new one replaced it is still grounded out "full-fielding" the alternator. This causes the alternator to put out its maximum potential which is BAD. Check to see if the voltage regulator is gettn "pulse-width" or is just simply grounded, if its grounded there is your problem.

That is right the car wiring is probably at fault here alternators do not like charging into an open circuit or loose corroded battery terminals. Or trying to continuiously charge a weak or dead battery. Some cars alternator locations are bad because the exhaust is near or the radatior cooling fans are blowing hot air on them. It is basic stuff your  Old Acura needs a good battery and strong wiring to the alternator

Answer 3

Im willing to bet you have an amp in your car and the sound system is still killing your alternator, I suugest you put a coil in to help take the load off the alternator that is proportionate to the system you are running. Good luck.
