INSPECTION

Measure the 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, the resistance will be more than 1 M ohm.

Note. When checking the continuity, wind a piece of tin foil around the tip of tester probe and press foil against wire with your finger.

Scheme 1

To locate the broken point, move the probe along antenna wire.

Scheme 2

Scheme 3

1. Clean the antenna wire and surrounding area with a cloth dampened by alcohol.
2. Paste a thin masking film on the glass along broken wire.
3. Deposit conductive silver composition (DUPONT No. 4817) on the broken portion with a drawing pen.
4. Dry out the deposited portion.
5. After repair has been completed, measure the resistance in repaired wire.

Scheme 4

1. Disconnect the ground cable from battery.
2. Remove the rear quarter upper trim. Refer to «REMOVAL»(ref-200811-S21299021622005102300000) , Rear Quarter Trim.
3. Disconnect the harness connector and terminal.
4. Remove the mounting screws and detach antenna amplifier.

Measure the antenna amplifier resistance.
