ELECTRICAL 16-29
Power is then transmitted through the transmission
shaft on bench seats and through the pulleys on
bucket seats, which in turn drives the actuator
cables. When the adjusters reach their limit of
travel, the drive cables stop their rotating action
and torque is absorbed by the rubber coupler con-
necting the motor and transmission on bench seats.
On bucket seats torque is absorbed through the
belt on the pulley. When the control switch lever
is released the switch contacts open, a spring re-
turns the shaft dog and solenoid plunger to their
original position disengaging the shaft dog from
the large gear dog. See "Seat Section" for ex-
ploded view of transmission.
Checking Procedure
It may be necessary to use only one or all of the
procedures outlined to locate an electrical failure
in the circuit. If the location of the failure is
evident follow only the steps required to check the
affected wire or component. If the location of the
failure is not evident, follow the procedures as
outlined. Before performing any extensive check
procedures, check the seat adjuster drive cables
for proper attachment. In addition, study the seat
circuit diagrams to become familiar with the seat
circuit. (See Figs. 16-69 and 16-70).

a. Checking for Current at Circuit Breaker
1. Connect one test light lead to battery side of
circuit breaker. If tester does not light, there
is no current at battery side of circuit breaker.
2. To check circuit breaker, disconnect switch
feed wire from breaker, and with a test light
