Jeff has no intention of putting in a relay to break apart the 24 volt  
bank when charging.  My understanding is that it isn't needed.  I had  
a long discussion with the dealer about this too.  They've used  
multiple 12V chargers like this often.

I really like the idea of the 12 volt chargers over a special 24 volt  
one.  It gives much better backup for any other charging requirement  
on the boat.

As an interesting side note, knowing that the old 24 volt charger  
couldn't be repaired, I ripped it open (breaking the plastic rivets)  
to get to the inside hidden areas.  In the middle of the electronics  
was an obvious large fuse.  After removing it, my meter showed an open  
connection.  Shaking it caused a momentary closure of the connection.   
Right now a replacement fuse is about $50.  If I can find a less  
expensive replacement, I'll rebuild it and see how it works.  You've  
got to wonder if something else failed causing the fuse blow though...
