My 1998 Southwind 35P has a CB115 rev a BCC. It looks like someone installed a fusible link (a wire that is designed to melt and separate with continued high current)between P13 connector on the electronic circuit board and the red wire that I assume goes to the Chassis Battery Disconnect. This seems to burn out occasionally and sometimes for no apparent cause. It has also burned out while working the hydraulic jacks. Does anyone know if this is supposed to be a fusible link, or should it just be a #10 wire?
The factory original was NOT a fusible link, however, it appears that something in your coach is occasionally drawing too much current and burning that wire, so someone installed the link to protect the circuitry.
Installing a circuit breaker seems like a good idea if you are not interested in finding the real culprit. I suspect it may be the step motor or slide motor, as the normal loads on that circuit are not that large individually.
Here is a schematic of your BCC so you can see the things that are normally attached to the chassis disconnect.
