TEST PROCEDURES Before any testing is attempted the battery should be carefully charged and all connections and terminals With dome lamp on, apply switch in direction of failure. If dome lamp dims the seat motor is trying to CIRCUIT BREAKER TEST Find correct circuit breaker on fuse block. Pull out slightly but be sure that circuit breaker terminals still HARNESS VOLTAGE TEST The following test will determine whether or not voltage is continuous through the body harness to the (1) Remove power seat switch from mounting posi- tion and disconnect switch from wiring harness. (2) Connect one lead of test light to ground terminal, black wire (BK) of center section, and touch other test (3) If test light comes on, harness to switch is good. If test light does not come on, perform circuit breaker MOTOR TESTS AA BODY (1) Remove switch from mounting position and dis- connect from harness. (2) To check the center motor, connect a jumper wire between pin 5 and pin 3 (Fig. 1). Connect a second (3) To check the front motor, connect a jumper wire between pin 5 and pin 1 (Fig. 1). Connect a second (4) To check the rear motor, connect a covered jumper wire between pin 5 and pin 6 (Fig. 1). Connect a second Ä POWER SEATS 8R - 1 |
