    >      Here's one way a small alternator can be mounted on a Renesis:
    >      * 60 amp Delco alternator (8 lbs)
    >      * Brackets made from 0.10 4130
    >      * the upper bracket uses 2 existing 8mm and 2 existing 6mm
   holes in the
    >      block
    >      * the lower bracket uses 3 8mm studs in the front housing
   (is this part
    >      of the housing strong enough?)
    >      * Alternator slide adjuster cut down from stock Rensis part
    >      * 12mm, 4" diameter idler pulley
    >      * Stock water pump pulley used to underdrive the alternator
    >      * Very ugly welding 8-)

   MARK, I DID NOT SEE THE PHOTO, BUT IF IT IS A SERPENTINE BELT, YOU
   NEED SPRING LOADED
   IDLER (ops, sorry for the caps). I had my belt tensioned with the
   alternator, but
   was starting to slip above 4000 rpm.

   The reason for the idler is to clear the RX8 magnetic pickup sensor.
   If you place the alternator lower to clear the mag pickup
   there will not be enough belt wrap on the e-shaft pulley
   to transfer the needed power.

Scott,
Looks like you made the right decision.  FWIW, Tracy can reprogram the
EC-2 to work with any CAS location.  You just need to tell him where it
is located.

We got a whole bunch of Marks and at least two Mark S's :)
