Welcome to the forum.
Here is a
Owners Guide for your coach.
Are you talking about a small inverter, one for the outlets for TV and electronics in over head cabinet in front of passenger seat. The inverter has a GFI outlet on it to send voltage to the outlets in coach and may need to be reset on GFI OUTLET.
This link for 06-07 fuse and wiring should cover your coach for many operations of items in your coach, its both for DP's and gas coach's.
This link will cover many other items in your coach and items you use in its operation.
You also need the BCO, battery cut off switch on to supply the inverter.
The BIRD battery charging system is also covered in the first link also, never operate slides on battery power, always shore power or Gen, so you stay out of more trouble.
Enjoy the forum and safe travels when you do.
