BODY
NOTE: Container should be placed in rear
compartment area of body, below level of fluid
in reservoir. In addition, sufficient fluid must
be available in container to avoid drawing air
into hydraulic system.
e. Operate top to down, or stacked, position.
After top is lowered fully continue to operate
motor and pump assembly (approximately 15 to
20 seconds) or until noise level of pump is notice-
ably reduced. Reduction in pump noise level in-
dicates that hydraulic system is filling with fluid.
f. Operate top several times or until operation
of top is consistently smooth in both up and down
cycles.
g. Remove hose from filler plug tubing and
remove filler plug adapter from reservoir.
h. Check level of fluid in reservoir and r e -
install original filler hole plug.
NOTE: Fluid level should be within 1/4 inch
of lower edge of filler plug hole.
92. Mechanical Checking Procedure
If there is a failure in the hydro-lectric system
and the cause is not evident the mechanical opera-
tion of the top should first be checked. If the
folding top assembly appears to have a binding
action disconnect the top lift cylinder piston rods
from the top linkage and then manually raise and
lower the top. The top should travel through its
up and down cycle without any evidence of a bind-
ing action. If a binding action is noted when the
top is being locked at the header, check the align-
ment of the door windows, ventilators and rear
quarter windows with relation to the side roof
rail weatherstrips. Make all necessary adjust-
ments for correct top alignment as described in
Note 86. If a failure continues to exist after a
check for mechanical failure has been completed,
the hydro-lectric system should then be checked
for electrical or hydraulic failures, as explained
in Notes 93 and 94.
93. Electrical Checking Procedure
A failure in the electrical system may be caused
by a "low" battery, breaks in wiring, faulty con-
nections, mechanical failure of an electrical com-
ponent, or wires or components shorting to one
another or to body metal. Before beginning check-
ing procedures, check battery according to r e c -
ommended procedures.
a. Checking for Current at Folding
Top Control Switch
1. Disengage terminal block from rear of
switch.
2. Connect light tester to central feed terminal
of switch terminal block.
3. Ground light tester ground lead to body
metal.
4. If light tester does not light there is an open
or short circuit between power source and switch.
b. Checking Folding Top Control
Switch
If there is current at the feed wire terminal
of the terminal block, operation of switch can be
checked as follows:
1. Place a #12 jumper wire on switch terminal
block between center terminal (feed) and one
motor wire terminal. If motor operates with
jumper wire but did not operate with switch,
switch is defective.
2. Connect jumper wire between center ter-
minal and other motor wire terminal on switch
terminal block. If motor operates with jumper
wire, but did not operate with switch, switch is
defective.
c. Checking Switch to Motor Lead
Wires
If switch is found to be operating properly,
switch to motor lead wires can be checked as
follows:
1. Disconnect green switch-to-motor wire from
motor lead in rear compartment, Fig. 16-125.
2. Connect a light tester to green switch-to-
motor wire terminal.
3. Ground light tester ground lead to body
metal.
4. Actuate switch to "down" position. If tester
does not light, there is an open or short circuit in
wire.
