I am going to tackle the problem of charging or lack of it for the house batteries. Where does the source from the isolater go to charge the house battery? I am not getting any voltage increase when I start the motor. Anyone have any good ideas? Dennis

Based on my cruiser groups responses I would suggest your isolater is the problem. If you have charging voltage levels to the isolater and no difference from battery voltage downstream the isolater has failed.
FWIW
