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-)

Scott,
Looks like a very good solution to me.  Let me ask one question.  Sincethe alternator is adjustable, is the idler really necessary?

Mark S.

The idler pulley is essential for the belt to clear the e-shaft
position sensor, which you see just below the pulley.  Ideally, a self-
tensioning idler would remove the need to adjust the alternator.
However, the space is very tight.  I looked a numerous tensioners in my
local auto parts shops (drove the guys nuts, too!), and none are
compact enough to work. They are also pretty heavy.

If one could re-mount the e-shaft sensor on the other side, and re-
program the ECU to understand this position, you wouldn't need the
idler.  This option appeared to be way too complex for me.
