(a) Disconnect the connector.

(a) Disconnect the connector.

(b) Remove the 2 screws and the power transistor.

5. INSPECT POWER TRANSISTOR OPERATION

(a) Connect the positive (+) lead to terminal 1 through a

(a) Connect the positive (+) lead to terminal 1 through a 12 V - 3.4 W test bulb and negative (-) lead to terminal 2.

(b) Check the test bulb comes on when another positive (+) lead is connected to terminal 4 through a 12 V - 3.4 W test bulb.

If operation is not as specified, replace the power transistor

6. INSPECT POWER TRANSISTOR RESISTANCE

Measure resistance between terminals 3 and 4.
