4 TECHNICAL SERVICE MANUAL
Kickdown Switch
To place the overdrive in overtake position
when car is in cruising gear at speeds above
30 M.P.H., depress the foot accelerator all
the way to the floor. In doing so, voltage
at terminal "K" (Fig. 4), of the overdrive
kickdown switch, is eliminated. This immedi-
ately de- energizes the overdrive relay coil
opening solenoid points "C". The solenoid is
de-energized. The solenoid return spring
tends to pull the pawl out of the sun gear
hub, but it is held in by side thrust. It is
necessary to reverse the drive line torque
for a moment. This is done by the interrup-
tion of the ignition system for approximately
two revolutions of the engine.
With kickdown switch points "L" and "J"
closed, the ignition primary circuit to the
distributor side of the coil is grounded by
the circuit completed through the ignition
interrupter points of the solenoid. As soon
as the solenoid is released, the interrupter
points are opened and the engine again fires
normally. The drive through overdrive is then
direct and conventional third speed
operation is obtained.
"Rambler" Series
Governor Circuit
The governor circuit starts from the
ignition switch terminal (Negative) on
the coil to the terminal "IGN" on the
overdrive relay (Fig. 6).
Then, passing through the relay coil
which magnetically controls the contact
points "B" of the solenoid circuit. it
continues from the "TH" terminal of the
relay to the kickdown switch relay
terminal "E".
Crossing the kickdown switch to termi-
nal "K", it passes to the governor
terminal "H" and its open contact points
"A".
Solenoid Circuit
The solenoid circuit starts at the "B"
terminal of the voltage regulator. It
then proceeds to the "B" terminal
