Hyundai Elantra MD/UD: 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.
|
| 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.
|

| 1. |
Remove the right side rear quarter trim.
Then disconnect the antenna feeder cable from the glass antenna
amp.
|
| 2. |
Turn the radio ON.
Measure the voltage between the harness side (A) and body ground
(B).
|
| 3. |
Check for FM wire resistance between terminals of No.1 and 3
1. FM antenna grid terminal
2. AM antenna grid terminal
3. Body ground.
|
| 4. |
Check for AM wire resistance between terminals of No.2 and 3.
|
