MicroController Control System
Systems Operation
NOTE :
The circuit diagrams have shaded lines for
illustration of current flow in each circuit.
Other circuits can be activated at the same
time, but each one is shown separately to
illustrate current flow in each individual
circuit.
This circuit supplies power to the MicroController
Control System and the Central Vehicle Monitoring
System(CVMS). It must be activated before power
steering, hydraulics or drive will operate.
When the battery is connected and the key switch is
closed, current flows from battery positive through
the key fuse, key switch, wire #5 to the logic connector
DD-1, and through the line contactor coil to battery
negative, then the line contactor will be closed.
The logic is connected to battery negative. The logic
circuits are powered up to accept voltage inputs and
create voltage outputs whenever the battery is
connected and the key is turned to ON.
The Central Vehicle Monitoring System(CVMS) is
also powered at this time. The CVMS first does
a “LCD test” which will light all the warning lights
