I have a 2005 Dolphin on a W24 chaissi. Problem is that the rv batteries stop charging by the engine charging system, I'm getting 14.5 plus volts from the engine and to the electrical control board in the right front compartment. Check all fuses and curcuit breaker, all good. any ideas. Question?: is there a relay that control voltage to the rv batteries from the engine charging system. all other charging from inverter and generator and shore power work fine.

It could be (sounds like) the diode isolation stack which allows power (charging) from the engine alternator / batteries to get to the house batteries but will not allow power (current) to be taken from the vehicle batteries by the house system.This protects the vehicle batteries from ever (sort of) being run down and assuring the vehicle can start.
Many times there is a relay that can be manually operated to tie the house batteries to the vehicle starting batteries should a “boost” be needed to start the vehicle.However, unless this relay is part of the diode isolation stack, I doubt it specifically is the problem.
