Kia Optima: Antenna. Repair procedures
Inspection
Glass Antenna Test
1. |
Wrap aluminum foil (A) around
the tip of the tester probe (B) as shown.
|
2. |
Touch one tester probe to the
glass antenna terminal (A) and move the other tester probe along the antenna
wires to check that continuity exists.
|
Glass Antenna Repair
To make an effective repair, the broken section must be no longer than one
inch. |
1. |
Lightly rub the area around the
broken section (A) with fine steel wool, and then clean it with alcohol.
|
2. |
Carefully mask above and below
the broken portion of the glass antenna wire (B) with cellophane tape (C). |
3. |
Using a small brush, apply a
heavy coat of silver conductive paint (A) extending about 1/8″on both sides
of the break. Allow 30 minutes to dry.
Thoroughly mix the paint before use. |
|
4. |
Check for continuity in the repaired
wire. |
5. |
Apply a second coat of paint
in the same way. Let it dry three hours before removing the tape. |
Glass Antenna Circuit Inspection
1. |
Remove the right side rear quarter
trim. Then disconnect the antenna feeder cable (A) from the glass antenna
amp.
|
2. |
Turn the radio ON. Measure
the voltage between the harness side feeder cable (A) and body ground (B).
OK : approximately 12V (ACC+)
|
|
3. |
Check for FM wire resistance
between terminals of No.1 and 3 1. FM antenna grid terminal
2. AM antenna grid terminal3. Body ground.
Standard value : 80~120KΩ
Short : Approx. 0Ω
Open : ∞ Ω
|
|
4. |
Check for AM wire resistance
between terminals of No.2 and 3.
Standard value : 120~170KΩ
Short : Approx. 0Ω
Open : ∞ Ω
|
|
5. |
Check the grid lines for continuity. |
6. |
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.
|
Antenna Cable
1. |
Remove the antenna jack (A) from
the audio unit and antenna.
|
2. |
Check for continuity between
the center poles of antenna cable.
|
3. |
Check for continuity between
the outer poles of antenna cable. There should be continuity.
|
4. |
If there is no continuity, replace
the antenna cable. |
5. |
Check for continuity between
the center pole (A) and outer pole (B) of antenna cable. There should be
no continuity.
|
6. |
If there is continuity, replace
the antenna cable. |
