INTERMITTENT 12 VOLT LOSS
It began after buying 2 new Interstate (6 volt?) Group 24 Deep Cycle replacements for our 6 year old Trojan 105 6 volts. Told the clerk in SC Boat/Rv store, we needed 2x6 volt Deep Cell, she quoted...

I suspect you might have damaged house battery voltage sensing circuit in the battery control center.
A) HOW DO I LOCATE THIS 'SENSING CIRCUIT' AND HOW WOULD I TEST IT? ASSUME THE BATTERY CONTROL CENTER IS IN INVERT/CONVERT/CHARGE AREA?
This circuit controls the battery disconnect solenoids and the cross connect to get power from the engine. Need to know the manufacture, model and revision number for a better idea what and where to check.
A) RIG IS A NATIONAL DOLPHIN 35 2008 , THE INVERT/CONVERT/CHARGE UNIT IS A XANTREX FREEDOM 10, IS THIS WHAT YOU ARE ASKING FOR?
One thing to try is next time you lose house 12VDC hit the AUX Start switch (with the engine off) and see if the lights come back on.
A) JUST DID THIS AND YES IT TURNED THE BATTERY DISCONECT LIGHT AND 12
VOLT IS BACK.
Really surprised the fridge controller didn't cook and it still operated on LP. Would have been interesting if you had tried to extend a slide (assuming they are electric and not hydraulic).
A) YES THE FRIDGE IS FUNCTIONING ON BOTH PROPANE AND AC FROM INVERT/CONVERT/CHARGER WHILE ENGINE RUNNING AND PLUGGED IN TO LAND POWER. ALL IS GOOD THERE, AND YES BOTH SLIDES ARE FUNCTIONING AS USUAL.
I JUST NOTED THAT AFTER THE 12 VOLT DISCONNECT LIGHT GOES OUT, THE INVERT UNIT CONTINUES TO RUN WITH COOLING FAN, SHUTS DOWN AND IN A MOMENT IT RESUMES AND KICKS BACK TO CHARGING 13.43 VOLTS TO THE HOUSE BATTERIES. THIS IS WHILE PLUGGED INTO SHORE POWER.
REALLY APPRECIATE THE ASSISTANCE. EUGENE.
