1996 Mini Cooper Repair Question
My car alternator is giving sound again and again
Is the alternator whinning howling?What kind of noise is it?Is the alternator spinning good when its not charging and the alternator is making noise?Is the belt slipping?
Hi Saturntech9, yes it is whinning howling like the voice of killing chicken. I fitted a volt meter to my dashboard. When there is whinning howling, the battery is not charged. Sometimes the sound will go off when I engage second or third gear. It is the loudest when during first gear. The belt doesn't seems slipping but it worn out pretty fast in just few months. Here in the picture I marked the place that give sound.

What year is the mini cooper?From the pic it doesnt look like a 1996 it looks much older.Also if you remove the belt and spin the alternator pulley by hand can you hear any abnormal nosies?Sounds like you could very well have a bad alternator.
It is a 1996 mini cooper, the engine was modified from injection to carburetor. I can't hear any noise if I removed the belt and spin the alternator pulley by hand. When I change a new belt, the sound gone, the battery get charged, everything works find but noises comes again after the car runs for 500 to 600km which I guess it shouldn't be. Could it be the bracket of the alternator isn't in good position or something? How can I check that?
