Thanks for the heads up, next time down I'll look at the Wiring. My Battery Merge Relay is in the Plumbing Bay on the Passenger Side. It does make sense that it would be what we in the Boating World called a Battery Combiner with an Override.
The Battery Combiner is a Constant Duty Relay that is energized and disconnected by Charging Voltage. There are other ways to connect all of the Batteries for Charging but this was the least expensive. HEART made what they called a Pathfinder or Pathmaker for charging a Battery Bank that had different Amp Hours from the Battery Bank that was being Charged and this may be an even better choice for my application.
Thanks again for the heads up.
