update on alternator noise over speakers

[Avi Meron]

You should have gotten one of my High Power alt....................not the
crap (of course not all of them are crap! But some surely are!) that you get
from other schmucks!

There is a suppressor that is attached to the back of the alt. it is BEHIND
the plastic cover on the alt. back.  If they neglected to reinstall it, that
could cause all kinds of fun problems..........
You might have to remove the alt. to check it out,
Take care,
Avi
Needless to say no car is immune from those noise issues, with or without my
alt..................(I thought I put that is this way I won't get too many
"un-nice comments").
