Don't know if this will help or not. I have not physically looked at these fuses. This is just a note I copied from a post for future reference if I needed it;
Fuse one - protects the battery and is located right AT the battery. If this is open everything works in the camper (including slides and stabilizers) when on external power, there is 13+ volts on the camper, and yet the battery will not charge.
Fuse two - protects the camper from the tow vehicle's charging circuit and is located near the pigtail junction box. If this is open (and you are on shore power), everything works inside at 13+ volts BUT the main slides, power stabilizers/jacks, and power tongue jack (if equipped) will not and the battery will not charge.
