8 TECHNICAL SERVICE MANUAL
Incorrect terminal locations of connecting wires.
Circuits grounded by water, dirt, or deformation.
Defective solenoid points.
Dirty or sticking relay contacts.
Insufficient travel or unsatisfactory contacts in
the kickdown switch. (Adjust or replace.)
Excessive end play in the governor shaft.
Improper adjustment of governor control springs
Burnt contact points in governor.
Damage to cap and contacts.
Absence of rubber cover to exclude water and
dirt.
Insufficient travel of shift rod. (Adjust control
cable to operating lever.)
CHECKING INOPERATIVE OVERDRIVE
Mechanical Checks
Determine if the overdrive control button is
pushed forward to the limit of travel.
Check to insure that the overdrive cable is
adjusted to move the overdrive lever firmly
against the stop on the overdrive housing in
the engaged position.
Electrical Checks
With the. ignition switch on, and the overdrive
button pushed forward, use a test wire or a
6-volt test light as follows:
Check the 30 ampere fuse in the overdrive
relay for live circuits and clean contacts.
Connect test lead directly from the hot
terminal on the circuit breaker to the
terminal "SOL" or No. 4 on the overdrive
relay mounted on the front of the cowl.
This will supply current to the solenoid
which should operate. It is does not,
check for a possible defective connecting
wire or connection at the solenoid termi-
nal before condemning the solenoid.
Ground the relay terminal "TH" or No. 3.
If the relay is functioning properly the
points of the relay will close and the
solenoid will operate. Ground the terminal
"E" on the kickdown switch. If all
circuits are correct to this point, the
solenoid should operate.
With the kickdown switch terminal "K"
grounded, push the plunger in. This breaks
the circuit and the solenoid should re-
lease.
If the solenoid operates in the above tests,
all circuits up to this point are correct and
further investigation must be conducted under-
neath the car.
Ground terminal "H" on the governor. The
solenoid should operate.
