Battery Control Center Fusible Link Mod Installed

Thanks for all of the replies. Even the one that suggests a solid wire to find the real culprit! I think I will install an auto-reset circuit breaker to try that first. I will also continue to find the high load.

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.

You might want to install an AUTO RESET CIRCUIT BREAKER in its place. This circuit breaker will OPEN during the heavy load period and then after it cools down for 2-3 minutes will auto reset. They look something like this...


Almost all installs have this FUSE in place to protect the wiring between the Battery and 12VDC Distribution. A typical battery can produce some serious DC AMPS for several minutes if the load is shorted out...

just replace with 10 gauge wire and you will find out soon enough
