g. Checking the Relay Assembly
feed connector slot on the harness, and ground
the other test light lead.
3. If tester does not light, there i s no current at
end of feed wire. Failure is caused by an
open or short in feed circuit.
f. Checking Wires Between Control Switch
and Motor Relay
1. Disengage 3-wire harness connector from re-
lay at motor.
1. Disconnect three motor leads from relay as-
sembly. These are the wires leading from the
motor to the relay.
2. Connect one end of a jumper wire to one of the
motor field feed studs on the relay and ground
the other end of the jumper wire.
3. Connect one end of test light to motor arma-
ture feed stud on relay and ground other tester
lead.
2. Insert one test light lead into the motor field
connector slot on harness and ground the other
lead.
4. With a jumper wire, energize the field stud
which is not grounded. If tester does not light
the relay is defective.
3. Actuate seat switch to energize field wire
being tested.
4. If tester does not light, there is no current at
end of wire. Failure i s caused by an open or
short circuit between end of wire and switch.
Check other motor field wire in the same
manner.
h. Checking the Motor Assembly
1. Disconnect the motor armature feed lead and
one of the motor field feeds from the relay
assembly.
2. With a jumper wire, energize the armature
