Under the hood you will have a BCC (Battery Control Center
) where your (3) relays are located. Go to the website and find the model you have under "Our Products" and read up on it... you need to have and use a multimeter for best effect.
Typically inside the BCC there is a 50A 'push to reset' breaker in the lower LH corner that feeds the DC fuse panel in the motorhome, maybe yours popped.
EDIT: Do you hear the relay "clunk" when operating either the chassis or house disconnect switches?
