Looked at the 2006 Dynasty this morning which has the intellitec system for house systems control. The Kitchen switch activates the 3 speed blower feeding the vents under the cabinet and curbside sofa. This function is available whether or not "furnace" is selected on the front thermostat or aqua hot is "on". Selecting "furnace" turns on a blower in the front dash console under the drawer even if aquahot is not "on". There is no fan speed selection at the thermostat when "furnace" is selected. It appears in order to get heat out of the aquahot heat exchanger vents under the kitchen cabinets and curbside sofa, the aqua hot must be on (110 or diesel), furnace must be selected "on" at the front thermostat and the aquhot blower switch in the kitchen must be on (3 speeds available). I'm not sure it can be configured to come on and off automatically when furnace and the desired temp is selected. That would be nice! 

Ok, so I replaced the ruptured turbo coolant line so I could do some voltage checks with the engine running. With no charging input, battery voltage was 12.8 vdc at the battery and positive lead on the alternator. When I started the engine, voltage dropped to 12.4 volts and slowly decayed. I removed and replaced the alternator thus afternoon and everything is normal. Chassis batteries are charging initially at 14.2 but within 5 minutes, decays to about 13.6 -13.8 vdc. I believe the alternator corrected the charging issues as both the Genny and shore power charging are Normal. Thanks for everyone's insight and feedback.
