Battery Control Box Connections

[99pa36b]

I have a 99 Pace Arrow Vision 36B built on the Ford Chassis, I need some electrical info. The drawings that Fleetwood sent me do not tell me what I need to know.

The battery control box under the hood is a model F73-1020.

There are a number of cables terminated on the left side of the box when viewed from the front. The larger cables are easy to identify as the chassis battery, coach battery and generator cables.

There are other smaller gauge cables that are terminated on the same side of the box. Does anyone know what devices they are connected to on the chassis or coach?

If it is like the 96 we had some years ago, there should be two relays in there. One is the emergency start (crossover) relay that closes when you push the Aux Start button on the dash - it parallels the house batteries with the chassis battery. The other isolates the house batteries from the chassis batteries when parked but closes to charge the house batteries from the engine alternator while driving. It may also be closed to provide chassis battery charging while on shore power.
