2. If you experience problems with radio reception, check for continuity in the connecting wiring of the antenna.
3. Wrap the ohmmeter probes with aluminum foil and probe the filaments of the receiving antenna array with it. One probe is pressed against one of the antenna terminals, the second one is drawn along the grating threads until a break point is detected.
4. If a break is detected, the grating is restored in a manner similar to that described in Section Check of serviceability of functioning and restoration repair of a heater of back glass for repairing the conductive rear window heating grille.
5. If the receiving array is in order, check the condition of the electromagnetic coil of the antenna amplifier. Disconnect the two wiring harnesses from the amplifier assembly. On the coil side of the 1-pin connector, check for continuity between the single terminal and ground. If there is continuity, replace the coil.
Note. Release the two cover fasteners on the underside of the amplifier to ease the disconnection of the connectors. Read the ohmmeter only a few seconds after connecting it. At the first moment, the device can fix the conductivity, which after 20 seconds can drop to zero. This test also checks the conductivity of the coil.
6. Check for continuity between the two terminals of the 2-pin connector on the opposite side of the amplifier assembly. If there is continuity, replace the coil (see remark to paragraph 5).
7. To replace the coil, remove the rear shelf (see chapter Body) and remove the two fixing screws.
