Probable Cause
(a) Deck unlock relay defective.
(b) No voltage at relay orange-
brown terminal. Also see 1 (b)
''Deck Lid Open."
(a) Maladjusted deck dosed limit
switch.
(b) Defective deck lock motor cir-
cuit or motor. Circuit and
motor are inaccessible until
deck is open.
(a) Broken flexible shaft or loose
lock nuts, one or both sides.
(a) Maladjusted deck closed limit
switch
allows top-deck motor
and pump to operate early in
phase and apply pressure to deck
lid hydraulic cylinders before
locks are clear.
Corrective Action
(a) Move top control switch to
down (retract) position. Listen
for ratcheting of deck lid locks.
Move top control switch to up
(erect)
position intermittently
and listen for click of deck un-
lock relay (behind rear seat back
cushion).
lf
no dick, remove
cushion and check for voltage at
orange-brown wire terminal. If
terminal is hot, relay is defec-
tive. Replace deck unload relay.
(b) Bypass deck unlock relay by
means of a jumper at connector
terminals, as shown in Fig. 10,
to activate deck lock motor.
(a)
A
maladjusted deck dosed limit
switch will allow the top-deck
motor and pump to operate and
apply pressure to the deck lift
cylinders and cause lock screws
to bind.
Release top control
switch and unlock deck lid as
outlined in 1 (b).
If
this fails,
deck lid wiH have to be un-
locked mechanically. See 3 (a),
"Deck Lid Open." See Fig. 18
for deck closed limit switch ad-
justment.
(b) If jumper is not effective in ac-
tivating deck lock motor, the
deck lid will have to· be un-
locked mechanically to gain ac-
cess to deck lock motor and
complete circuit. See 2
(a),
"Deck Lid Open."
(a) Unlock deck lid mechanically.
(a) When deck lid has been opened,
adjust deck closed limit switch.
