Loss house power & gen won't start (2015 Thor Tuscany XTE)

[dchouk]

Just came back from a trip. Ran generator during trip and when I got home, I turned off TV, satellite dish, AC, etc. and then shut off generator and then turned engine off. After everything was off loaded, I started the coach and headed to our storage yard and noticed I had no cameras operational and could not start them, the radio, or anything from the radio controls. When I got to the storage yard, I could not start the generator, noticed the house batter switch was not activated, however, could not get it to start or light up as it usually does. The engine will start just fine, but everything in the coach is dead or won't work (lights, slides, etc.). Looking for advice. Thanks.

1) measure house battery voltage >12V good enough ,11 replace batteries
2) search back from battery for voltage to 12V to power panel; 50A breaker and main power switch ("use" switch) .

The engine alternator should have been charging the house batteries if the switch was in the use position and the power relay is functional. I assume, in your case , the house batteries are too low to switch this relay or you have blown the 50 A protection fuse (located close to the batteries), maybe due to a house battery shorted cell?

This should be easy to locate if you are methodical is your analysis. Good Luck
