On startup, the belt on my 95 will squeak for a long time before it quiets down. Normally I would just replace the belt but there is a pile of belt powder on the face of the alternator. I wiped it off and ran the vehicle for less than 5 minutes. I shut it down and removed the serpentine belt. The alternator was covered in belt dust and the pulley was hot enough to burn my hand. The body of the alternator was quite hot as well. The battery is not dead.
The alternator coils looked pretty dark to me but when I was looking at the price of new alternators, the coils in the pictures look to be the same color.
The other thing that makes me suspect the alternator is the tach does not work. When the vehicle is running the tach will sit at 500 RPM regardless of actual engine RPM. Rarely the tach will function normally but not very often.
Thoughts?
