Electrical Circuit
The
electrical circuit includes:
•
Drive motor control switches. When
the
emergency/parking
brake
is
applied,
these switches shut
off
power
to the
drive motor.
•
Power steering control switches. With
the key
switch
in the
"on"
position
the
power steering
pump
will operate
if the
brake
is
released
by
depressing
the
pedal
or if the
tiller
is
turned.
•
Lift
pump
control switch.
The
lift
pump
operates only when
the
multi-function handle
is
moved
to the
RAISE position
and the
battery
is not
discharged
to
80%.
•
Auxiliary Pump Control Switches.
The
auxiliary
pump
turns full
on
when
one of the
push button switches
on the
multi
function
handle
are
closed
and
held closed while moving
the
handle
to
activate
raise
or
lower switches.
•
Static Return
to Off
(SRO).
The SRO
circuit
in the
traction control
shuts
off
whenever
the
emergency/parking brake switch
or key
switch
is
opened (brakes applied). When
one of
these switches
is
opened,
the
traction control shuts
off and
cannot
be
restarted
until
the
multi-function control handle
is
returned
to
NEUTRAL.
A
time
delay
(1
second)
is
built into
the
control
to
allow momentary
opening
of the
brake switch
if a
bump
is
encountered.
If
you try to
start
the
truck with
the
direction control lever
in
FORWARD
or
REVERSE, afault code
of
-02, -03,
or -04
appears
on the
diagnostic display.
A
fault code
of -01
appears
on the
diagnostic display when
the
emergency/parking brake
is
applied
and the key
switch
is ON.
