This system is designed for twin
outboard installations using outboards without Aux
outputs. It will allow the port engine to charge the port
start battery and the house battery when the port VSR is
engaged (Refer VSR spec for operation of VSR). It will
also allow the starboard engine to charge the starboard
start battery and the house battery when the starboard VSR
is engaged, giving a combined charge from two outboards
into the house battery until the voltage regulators on
both engines control the charge. It will also allow the
house battery to be charged if steaming on one engine.
