What fuses are blowing? With that information, we can dig into the wiring and maybe figure out the cause.

The 4WD fuse (#19 - 20A) supplies power to the +12V motor feed inputs to the TCCM (transfer case control module) and then on out to the encoder motor itself. I would test the wiring from the fuse to the TCCM & from the TCCM out to the encoder motor for shorts to ground. Test it while moving the connectors & harnesses around.
