Re: [DML] Alternator Issues

I had a similar issue with alternators too.  First replacement I got caused
my volt gauge to jump all over the place.  Second one had a bad regulator
from the beginning and cooked my Optima, (I wondered why my binnacle was so
darn bright).  Thrid one is working fine for almost a year now.

I also had that same exact pulley you describe.  I puchased Toby's custom
one and it's perfect.

I was told if you tighten the belt too much it will wear the bearings much
