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 screened 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.
B.
Free play in the antenna rod
Free play/poor contact between the various sections of the antenna rod may occur. Check this as described below:
1
Switch on the radio and let the antenna extend to its fullest height.
2
Take a resistance reading across the top of the antenna rod and the centre pin of the antenna/aerial connector.
3
If the reading obtained is more than 30 ohms the antenna/aerial rod should be changed.
4
Connect the antenna cable.
5
Tighten the nut at the base of the antenna (unless this has already been done) and the two nuts securing the antenna/aerial.
