Two 12 volt batteries are connected in series to supply 24 volt DC power to the machine electrical system. 24 volt power is supplied to fuse assembly (2). The fuse assembly protects the batteries from circuit overload between the fuse assembly and the electric starting motor. Main circuit breaker (4) protects the electrical circuit between the main circuit breaker and the circuit breaker panel from circuit overload.
Auxiliary start receptacle (3) is available to jump start the machine. When jump cables are connected to the auxiliary start receptacle from a 24 volt DC electrical source, the machine may be started.
The auxiliary start receptacle may also be used as an auxiliary power outlet source to supply 24 volt DC power to service equipment.
