Probable Cause
(e) Defective
deck
closed
limit
switch. Deck lid open for ac-
cess.
(a) Maladjusted deck closed limit
switch.
(a) Defective power circuit to top-
deck motor and pump or deck
control solenoid.
(b) Defective deck lock motor cir-
cuit or motor.
(c) Broken
deck lock flexible
shaft(s).
(d) Faulty deck control solenoid
valve or top-deck motor and
pump assembly power circuits.
(e) Faulty deck control solenoid
valve.
Corrective Action
(e) TOP CONTROL SWITCH RE-
LEASED. Using a self-powered
test light, check for open circuit
between yellow wires, red wires,
and white wires of switch.
If
test
light fails to come on for any
check, switch is defective. Re-
place deck closed limit switch.
(a) Raise the deck lid manually until
deck motor and pump become
energized. After deck lid is open,
adjust deck closed limit switch.
See Fig. 18.
(a) A defective power circuit or
defective motor or solenoid will
prevent deck opening regardless
of relay function and will be
evident when relay jumper is
applied. See 1 (b). Deck lid
must be opened mechanically to
gain access for repairs.
(b) TOP CONTROL SWITCH RE-
LEASED. If deck lock motor is
not functioning, check power
circuit for voltage at motor red-
yellow wire terminal. Deck lid
should be open, sufficient for
access, only to avoid reposition-
ing of deck open limit switch
L.H. If no voltage, repair the
circuit. If terminal is hot, motor
is defective. Replace deck lock
motor.
(c) TOP CONTROL SWITCH RE-
LEASED. Unlock deck lid me-
chanically. With deck lid open
check deck lid lock shafts and
lock nuts. If shaft ( s) are bro- ·
ken, replace shafts. Otherwise,
tighten lock nuts.
(d) Open deck lid mechanically.
Check solenoid and motor cir-
cuits. Repair faulty circuit (Fig.
5).
(e) TOP CONTROL SWITCH RE-
LEASED. Open deck lid me-
chanically, sufficient for access.
If
circuit checks out hot at blue-
red terminal on valve and the
top-deck motor and pump oper-
ates when top control switch
is momentarily depressed, but
there is no action at deck open-
ing cylinders, the solenoid valve
is defective. Replace valve.
