ELECTRICAL SYSTEM-Continued
Alternator, Battery, and Starting Systems (Vehicle S/N 18,550 to 199,999)
Continued.
5.
A remote start system allows the operator to start and stop the engine while the cab
is tilted. The OFF IGN and OFF ST switches are located under the cab on the right
side of the vehicle, next to the alternator. Placing the OFF IGN switch in the on
position supplies battery power to the 12 VDC and 24 VDC ignition relays.
Momentarily holding the OFF ST switch in the on position starts the vehicle.
6.
Three switches are provided to allow the operator to disconnect the batteries from
the system. The Battery Disconnect switch, located in the cab on the lower left side
of the instrument panel, disconnects the batteries from the electrical system and
shuts down the engine. The Manual Battery Disconnect Switch (MBDS) is located
under the battery disconnect enclosure near the air tanks, and allows the operator to
physically disconnect the batteries from the system. The remote OFF BAT switch is
located under the cab on the right side of the vehicle next to the remote start
switches. Placing the OFF BATT switch in the off position disconnects the batteries
after a one-second delay. To prevent alternator load dump (voltage spike), the
MBDS and OFF BATT switches should not be used to disconnect the batteries while
the engine is running.
