POWER SEAT
GENERAL INFORMATION
The power seat system is protected by a 20 amp
circuit breaker located in cavity CB2 of the fuse
block. This circuit breaker is HOT at all times. Cir­
cuit A7 is the power supply for the circuit breaker.
The A7 circuit originates in the Power Distribution
Center (PDC) and is protected by a 50 amp fuse lo­
cated in cavity 1.
Circuit F37 is the feed for the switches and the
seat motors from the circuit breaker. A BUS bar in­
ternal to the switches feeds all the contacts. Ground­
ing for the seats is provided on circuit Z3.
DRIVER'S SEAT
When the operator selects the FRONT VERTICAL
UP function, power is passed on the F37 circuit
through the closed contacts in the switch to the P19
circuit. The P19 circuit connects to the motor.
Ground is provided on the P21 circuit back to the
switch. A ground BUS bar internal to the switch then
connects it to ground on the Z3 circuit.
For FRONT VERTICAL DOWN function the cir­
cuits are reversed. P21 is the feed, and P19 is the
ground.
When the operator selects the HORIZONTAL FOR­
WARD function, power is passed on the F37 circuit
through the closed contacts in the switch to the P15
circuit. The P15 circuit connects to the motor.
Ground is provided on the PI7 circuit back to the
switch. A ground BUS bar internal to the switch then
connects to the Z3 circuit.
For HORIZONTAL REARWARD function the cir­
cuits are reversed. PI7 is the feed, and P15 is the
ground.
When the operator selects the REAR VERTICAL
UP function, power is passed on the F37 circuit
through the closed contacts in the switch to the P l l
circuit. The P l l circuit connects to the motor. Ground
is provided on the PI3 circuit back to the switch. A
ground BUS bar internal to the switch then connects
to the Z3 circuit.
For VERTICAL DOWN function the circuits are re­
versed. P13 is the feed, and P l l is the ground.
