Battery Charging Problem ***UPDATE***
While dry camping in freezing weather, the charging system died for the dual type 24 house batteries (2002 Winnebago Mini). It appears to be a solenoid system. It failed two years ago and the RV s...

The EMC on the engine will "see" the starter battery voltage. It will drop the voltage down fairly quickly.
That is why a DC to DC voltage boosting device works better. You will still need a solenoid so that the starter battery is isolated from the house batteries when the engine is not running.
Starter battery-->solenoid-->dc to DC device-->house batteries.
Do not set the dc to DC unit output higher than 15.3 volts output.
