Jamie: Here is a schematic and information sheet I found on the BCC. It's operation is similar to how the BIRD/Trombetta function. It just uses an internal interconnect relay found in the BCC to act like the Trombetta does.

It says:

"Normal charging of the chassis and coach batteries as a set depends upon which disconnect is closed. For example, if the coach is underway and the chassis battery disconnect is engaged, when the chassis battery charges to 13.2 vdc from the engine alternator, the interconnect relay will pull in after a 15 sec delay. If the engine were to be turned off, when the chassis/coach battery set discharges to 12.6 vdc, the interconnect relay disengages after the 15 sec delay. When the coach is on shore power and the coach battery disconnect is engaged, the converter will charge the coach battery until it reaches 13.2 vdc. at which time the interconnect relay will close after the delay. As before, should shore power be disconnected, the coach chassis battery set will discharge to 12.6 vdc, and the interconnect relay will release the delay. The interconnect relay requires 0.5 adc for its coil whenever it is engaged"
