Antenna Amplifier: Testing and Inspection

DIVERSITY & RADIO AMPLIFIER INSPECTION
1. Disconnect power connector 1P (A) from the diversity.




2. Turn the radio ON. Measure the voltage between the harness side power connector and body ground.

OK : approximately 12 V (ACC+)

3. Remove the radio feeder cable from the diversity and radio amp.
4. Check for continuity between diversity and right side radio amp feeder cable (B).
5. Check for continuity between diversity and left side radio amp feeder cable (C).




6. Disconnect the 2P power connector from the glass antenna radio amp.
7. Check for continuity between terminals of harness side connector and antenna grid terminals (AM, FM).
8. Check the grid lines that continuity exists.
9. When a poor radio reception is not repaired through the above inspection methods, replace the amp. If the radio reception is still poor, check the radio cable for short and radio head unit for failure.
