Almost everything in the front cab, not installed as part of the Ford F53 stripped chassis, for the coaches made in plant 750 is powered by the chassis battery. The chassis battery has a 100 amp circuit breaker just beside the chassis battery. This CB powers the cap fuse and relay board located down by the driver's left foot. This circuit board has the fuses and accessories inhibit relays for the steps, shade, slides, jacks, fans, patio awning, etc.
