[C320-list] Alternator Upgrades

The short answer is that I have the BALMAR alternator with its controller
and I really like it. http://balmar.net/  The best price was from PYA.

http://www.pyacht.com

The long answer is a consideration of how to best set up your 320.  I have
discussed this and it is on file on the C-320 pages.

WE needed extra power about 15 days a year when we are on a buoy at
Catalina.  I found it better to have the large alternator instead of a HONDA
generator.  No need to mess with fuel, storage etc.  

My set up includes: ( from a 2002 email)

The web site has a great discussion on this and Jeff may want to add these
suggestions to the Q&A section.  What I did on WindWalker II was the
following and I highly recommend it:

1. Set up #1 switch position for the new Group 27 AGM start battery 2. Set
up # 2 switch position for the existing batteries which were placed in
parallel.
3. Installed a 50A Two Battery Combiner (C-50)  for charging the batteries
from the engine alternator.  (West marine Model 143268 $79.99 on page 520,
2003 Catalogue.)  This allows the engine alternator to charge both banks
that you have now created and not only charge the weakest bank.. I placed
this small device behind the DC panel.
4. Placed the group 27 AGM battery in the port lazier just below the ac/dc
shore power charger.  I had to epoxy a bracket to hold it onto the bottom of
the lazier.
5. By the way, I was not satisfied with the Catalina original battery
charger so I had it deleted from the equipment list when I purchased the
boat and in stead installed the True Charge 20+ charger. (West Marine page
529) This allows me to charge both banks.  Over the past few years many on
this list have changed to this equipment.  It work fine and does not fry the
batteries.  Yesterday I check my batteries and only had to add 2 cups of
water after 2 months.
6. While you are at it you should consider adding the Link 10 battery
monitor for observing the battery charge in group #2. (page 520).

I like the idea of using group #1 for 1 battery and Group #2 for the 2
batteries, easy to remember.  I also can with this set up use up all the
juice in group #2 if I screw up, and still have power for starting the
engine since the banks are not connected are not connected unless I select
Both.  I never set the switch to both in practice,  although this could be
useful in an emergency.  The selector switch selects what is being used not
what is being charged by either shore or engine power.

If this helps and If you have further question please give me a call.



Cheers,

I know people have upgraded their alternators - I would appreciate any 
suggestions as to various upgrades installed.
Thanks
