SCHEMATIC CHART
Measure resistance between antenna terminal and each antenna wire.
If an antenna wire is OK, resistance will be Less than 1 ohm. If an antenna wire is broken, resistance will be More than 1 Mohm.
Note. When checking the continuity, wind a piece of aluminum foil around the tip of tester probe, and then press the aluminum foil against wire with your finger.
Scheme 4
To locate the broken point, move the probe along the antenna wire.

Scheme 6
- Clean antenna wire and the surrounding area with a cloth dampened by alcohol.
- Paste a thin masking film (B) on glass along the broken wire.
- Deposit heat wire repair agent (C) (DUPONT NO. 4817) on the broken portion (A) with a drawing pen.
- Dry out the heat wire repair agent portion.
- After repair has been completed, measure resistance in the repaired wire.
