[DML] Re: alternator noise



I vote for #1 and #3. Get a string or a straightedge and check for
alignment. To see if it is loose WITH THE MOTOR OFF try turning the
alternator pulley. If you can turn it by hand, and the belt slips,
tighten it up a little. Another "trick" is (while the motor is running
so be careful) while you hear it squeaking, spray some water on the
belt. If the noise goes away you have confirmed the belt that is
noisy. An alternator that is outputting will give off a high pitched
whine. Once the battery is fully charged the whine should diminish.
Squeaks can also come from the idler bearings for the A/C. If they are
origional they should be replaced. The wrong belt can also squeak.
Look at the bottom of the "vee" belt. If it is shiny it is riding on
the bottom, it is not supposed to, it is only supposed to touch the
pulley on the sides of the vee.
