or out, or when window switches are moved to "up" position,
electrical current may not be entering the system. Use a test
lamp to check the current at the circuit breaker located
under the instrument panel to the left of the steering
column. On Convertibles equipped with hydraulic win-
dow regulators, a 30 ampere circuit breaker is provided in
addition to the standard 20 ampere circuit breaker. Apply
one lead of the test lamp to the battery (forward) terminal
of the standard circuit breaker, which is located above the
30 ampere circuit breaker, and ground the other lead. If the
lamp fails to light, no current is reaching the system and the
power lead to this terminal from the "BAT' terminal of
the voltage regulator should be checked for short or open
circuit.
If the lamp lights, move the test lead to the auxiliary
(rear) terminal. Failure of the lamp to light here indicates
the circuit breaker is faulty and should be replaced. Move test
prod to rear terminal of 30 ampere circuit breaker if car is
equipped with hydraulic wind o w regulators. No light at this
point indicates faulty connection between "BAT" terminal of
20 ampere circuit breaker and "BAT" terminal of 30 ampere
circuit breaker.
WINDOW LIFT CONTROL SWITCH
With current reaching the "AUX " side of the 30 ampere
circuit breaker, the pump motor should operate when window
switches are moved to "up" position. If motor fails to op-
erate, or if windows fail to open with switch in "down"
position, each switch should be removed and checked.
NOTE: If motor operates when quarter window switches
are moved "up" but fails to operate from door switches, a
loose connection or broken wire at the forward terminal on
the top operating switch is indicated. The window control
switches are held in place by spring c lip s and may be
removed by using Switch Removing Tool No. KMO-685.
With terminals on back of switch exposed, ground one
lead of the test lamp and attach one lead to the center terminal,
marked "BAT". This terminal is normally "hot", and the
light should light with the switch control knob in any position.
With the knob in "up" position, the upper or "MO" terminal
should light the test lamp. Current should reach the lower or
" CYL" terminal with the control knob in both "up" and
"down" positions.
TOP OPERATING SWITCH TEST
If top is up, unhook top from windshield header before
testing top operating switch.
Check adjustment of top control rod. The rod should
extend 1/8" through the retainer on the switch at (A),
Figure 148. There should be 1-3/8" clearance between the
base of the top control knob and the face of the retaining nut
on the instrument panel for Models 1948 thru 1950 and
1-3/16" for all Models 1951 thru 1954, shown at (C), Figure
150. Make adjustment at (B), Figure 156. The pump motor
should operate when the top operating knob is pulled out or
pushed in. If motor fails to operate, use the test lamp to
check whether current is reaching the switch. Current is
-carried to a terminal on the face of the switch from the
"AUX" terminal on the circuit breaker. If current is reach-
ing the switch, failure of the test lamp to light from the side
terminal when the top operating knob is pulled out indicates
that the switch i s inoperative and should be replaced.
MOTOR SOLENOID SWITCH
If the foregoing tests indicate correct battery gravity,
and if window and top operating switches operate satisfac-
torily, but motor fails to operate, it will be necessary to
remove the rear seat cushion and rear seat back to gain
access to the well containing the Hydro-Lectric unit.
Check the connections from the battery to the solenoid
switch and from the solenoid to the motor.
Current should reach the switch (center) terminal of the
motor solenoid when window switches are moved up or top
control knob is moved in or out. A distinct "click" will be
heard if solenoid is operating satisfactorily.
If current does not reach the switch terminal, wires from
the window and top operating switches should be checked
for open or short circuit. Operation of the solenoid may be
checked by disconnecting the wires from the switch terminal
