[C320-list] Rough idle on diesel due to Balmar Alternator?

[Richard A. Walker]

It is probably the engine.  The westerbeke runs ruff at idle.

I'm new to the C320 IA.  Bought hull 273 a couple months ago, keep in Long
Beach CA, and am in the process of fixing all the little gremlins on the
boat.  Wife and I really like the boat and I'm glad to have found this
association.  
   
  Hull 273 (Westerbeke 30B3) has a very rough, loud, vibrating idle at
times.  It is intermittent.  I think it has to do with the high output
Balmar alternator that was installed.  At 80amps, which equates to 3 to 4hp
(~10% of peak hp), engine idle is reduced as there is no automatic idle
compensation like todays car engines.  Normal idle is 1150rpm, sometimes it
drops to 600rpm.  After contemplating this for a while I've come to the
conclusion that it must be the alternator.  I'm not certain this is the
reason.  Has anyone else experienced this with their diesel's after
installing a high output alternator?
To solve this I'm investigating an on/off switch for the regulator but I'd
like to be certain this is the problem.
