TOP ERECT CYCLE
The top erect cycle utilizes the
same motors as the top retract cycle.
These motors, however, operate in
the
reverse direction of that for the
retract cycle in the upper hack panel
retract, top erect, and top lock
Probable Cause
(c) Defective top down limit switch.
See top retracting phase.
(d) Defective
deck
closed
limit
switch.
(a) Defective deck control solenoid
valve.
(a) Defective top-deck motor and
pump assembly or power circuit.
(a) Defective deck lock relay. Deck
lock relay is activated simul-
taneously with deck close re-
lay.
(a) Open power circuit to deck lock
motor or defective deck lock
motor.
phases. The circuits, switches, and/ or
switch
positions
differ
in
the
various
phases. All checks and tests de·
tailed in the Top Erect Cycle Diag-
nosis Guide are to be performed
with the top control switch pushed
up (erect position).
Corrective Action
(c) Check between violet-white wire
terminal and red wire terminal
on top down limit switch with
self-powered test light.
If
light
fails to come on, switch is ·de-
fective. Replace top down limit
switch.
(d) Check between red wire termi-
nals on deck closed limit switch
with self-powered test light.
If
light fails to come on, switch is
defective. Replace deck closed
limit switch.
(a) Check for voltage at deck con-
trol solenoid valve lead.
If
wire
is hot, solenoid valve is defec-
tive.
If
wire is dead check power
circuit and repair.
(a)
Check voltage at the yellow wire
at top-deck motor and pump as-
sembly. If wire is hot, motor
is
defective. If wire is dead, check
power circuit and repair.
(a)
Check for voltage at the violet-
red wire terminal of relay. If
wire is hot, deck lock relay is
defective.
If
wire terminal
is
dead, check for break in violet-
red wire to violet-white wire cir-
cuit to the deck closed limit
switch. Repair circuit.
(a) When deck lid starts to close,
observe deck lock mechanism.
If deck lock mechanism is not
functioning disconnect the motor
leads at the motor. Use a jumper
between motor yellow-red lead
and yellow-blue wire receptacle
of deck lock relay connector. If
motor operates, power circuit
(yellow wire) is open. Repair
circuit. If motor
does
not oper-
ate, motor is defective. Replace
deck lock motor. Release top
control switch.
In the event of a stop in the cycle,
release the control switch to avoid
burning out a motor. If jamming
is suspected, do not reactivate the
control switch for over five sec-
onds at one time until the condi-
tion is cleared.
