Found a potential disaster waiting to happen.  I notice that my coach batteries (Interstate 8D) where cooking on shore power in the float charge mode.  Went back into the settings on the Heart Interface Link 2000 and found the battery amp hour setting set to an abnormaly high number (don't remember the number).  The batteries had a marking of "CCA 1400" with no AMP hour markins.  The battery manufacturing spec is a 270 AMP hour rating.  Given two parallel strings I changed the setting to 540 amp hour capacity.  The batteries are now charging as they are supposed to be charged.      NOTE;  Just realized what I wrote, this setting is incorrect.  I can't have two parallel strings as that would be 24 volts.  If the battery installation was done correctly there should be six 12v batteries in parallel given me 1620 amp hours @ 12v.  I will have to go back and check the layout to verify.  

What I suspect happened, someone changed the AMP hour setting (recent battery install) to some number based on the CCA rating which resulted in the charger thinking we had a huge battery bank.  If this setup had continued unabated I would be buying new batteries before long.
