Alternator Electrical noise and Belts?

[Jim Green]

Two questions/issues,

One, what kind of alternator belts are you guys using?
 I’m on belt #4 in the last month, I’ve tried Conti
-SF11, 2x866, Gates, Dayco, and some other truck stop
brand.  I swear I go through this every two years, the
last belt that went the distance was a Dayco.  I threw
that at 6800 rmps in third gear last month.  I’ve
verified the pulley is lined up, Any other brands I’m
missing?

Two, what causes alternator noise?  I’ve replaced my
brushes and voltage regulator with no luck.  Do I just
need a new one?  Mine’s 205,000 miles old.  I realized
it’s the cause of all my electrical system noise when
my O2 gauge went silent once the belt came off today.
The gauge is grounded to the IM.

Thanks!
