When your generator is running are you getting AC within the RV (does your microwave work?) If not - then check the fuse/circuit breaker on the generator.
When connected to shore power are your coach batteries charging? If not then check the fuse on the converter and/or look for an auto reset circuit breaker near the batteries (when they go bad your battery won't charge). You should Google for pic of auto reset circuit breaker as they look kinda weird. Also make sure you haven't accidentally toggled the battery disconnect switch - common mistake.
Also - it takes a long time for batteries to charge using either shore power or generator so keep that in mind.
