A. Antenna's Ground Connection Unsatisfactory

It is extremely important for the antenna to be properly grounded. This can be checked as described below.

1. Fold aside the luggage compartment trim behind the left-hand wheel housing.

2. Disconnect the antenna cable.

3. Undo the two nuts securing the antenna.

4. Place a piece of insulating paper between the antenna bracket and the car body.

5. Take a resistance reading across the antenna connector's shielded plug and grounding point G3 below the left-hand rear light cluster.

6. If the reading obtained is less than 10 ohms the ground connection is OK. Remove the paper and continue with point B.

7. If the reading is above 10 ohms, adjust the lock washer until it is in good contact with the body metal.

8. If the resistance reading obtained is less than 10 ohms after adjusting the washer, remove the paper and continue with point B.

9. If it is greater than 10 ohms there may be an open circuit in the antenna. Change the antenna/aerial and continue with point C.
