House 12 volt drops out.

[stuben]

I have a 2008 camelot 42 DSQ. My issue is when I use a heavy load on the house 12 volt system ( slides, sanicon all 3 fantastic fans on high) the entire house power drops out for 1-3 minutes and then restores. I do not loose chasis 12 volt or any of the 120AC, only house 12 volt DC. I have checked the battery disconnect solenoid and it is OK. Intellitec tech told me I have a loose ground. I did finally find and clean the main grounds to the chassis ( located behind the battery compartment) still have the same issue. Batteries are new. Any ideas or suggestions welcome.  Thanks Doug

Are you plugged into shore power when this happens, or are you dry camping?

We are plugged in to 50 amps.

Do you have you Charger turned on?  It should be able to handle up to 100 Amp load.

I had a similar issue with randomly losing house power that was difficult to diagnose. It acted like a bad ground but turned out it was the house battery disconnect solenoid, which is a continuous duty solenoid. Once diagnosed and replaced, I cut the top off the old solenoid to see if I could determine the cause. It was corrosion on the plunger. In some positions it would have good contacts while other positions would not.

May not be your issue but with a look.

Good luck!
