IGNITION SWITCH CIRCUIT TO EIC BOARD
Battery voltage
The power originates at the battery and proceeds
through the (R) battery cable to the starter solenoid.
From there power continues through the (R) wire to
the battery side of the start relay.
The power continues through the (R) wire to the
preheat circuit breaker, then through the (R) wire to
the engine fuse panel (standard fuse block) battery
side of the key main 15-amp fuse.
The power continues through the (R/W) wire to the
battery terminal of the ignition switch.
SECTION 55 - ELECTRICAL SYSTEM
When the ignition key switch is turned to the "ON"
position, power continues through the (O/PU-2) wire
to the Electronics 5-amp fuse in the cab fuse panel.
The power continues through the (O) wire to terminal
12 of connector P2 at the EIC board.
NOTE: Also, with Key Switch "ON" Engine "OFF,"
voltage travels from the switch "ACC" terminal via the
LTGN/B wire to terminal 11 of connector P1 to
provide a warning of Key "ON" should the operator
exit the skid steer.
