Application: Fleetwood class A diesel coaches
Description: This BCC has 2 disconnects and a BIRD (Bidirectional Isolator Relay Delay). The isolator relay is external.
Documentation: In 2010, Fleetwood added a second relay externally for aux start service. It is part number 3A-120 by S&N manufacturing. Consequently, the troubleshooting guide is not accurate in the aux start and charging areas. Be aware of 2 300A fuses in the charging path. A Fleetwood wiring diagram is provided for reference. Also, the transient reduction feature (release delay of charging relay) is disabled.
