7) Fasten the another side of extension harness (B)
to end of printing pattern of grid with tape.

8) Connect the ground cable to battery.
9) Turn the ignition switch to ON.
10) Turn the rear defogger switch to ON.
11) Wrap a piece of aluminum foil around the tip of
tester probe and press foil against wire with your
finger.

12) Measure the voltage around an antenna wire
(a) and (b).

NOTE:
Measuring point (a)
• If the measured value is 6 V, heat wire is open
between antenna wire center and positive (+) ter-
minal of probe.
• If it is 0 V, the circuit is open between antenna
wire center and ground.
Measuring point (b)
• If the measured value is 12 V, heat wire is open
between antenna wire center and positive (+) ter-
minal of probe.
• If it is 6 V, the circuit is open between antenna
wire center and ground.
13) Fasten the voltmeter positive (+) side and neg-
ative (–) side to end of open harness of step 12).
14) Search a point the voltage changes from 0 V,
move the negative (–) probe along antenna wire.

15) Repair the antenna wire that determine the
place of the open circuit. <Ref. to ET-14, REPAIR,
Antenna.>

2. TYPE B

Measure the resistance between the antenna ter-
minal and each antenna wire.

1) Disconnect the ground cable from the battery.
2) Wrap a piece of aluminum foil around the tip of
probe and press foil against wire with your finger.

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

NOTE:
If an antenna wire is OK, resistance will be less
than 20 

:.

If an antenna wire is broken, resistance will be
more than 1 M

:.

4) Repair the antenna wire that determine the place
of the open circuit. <Ref. to ET-14, REPAIR, Anten-
na.>

B: REPAIR

1) Clean the external circumference of antenna
wire and around with alcohol or white gasoline.
2) Paste a thin masking film on the glass along bro-
ken wire.
3) Apply the conductive silver composition (DU-
PONT No. 4817) on the broken portion with a draw-
ing pen.

4) Dry out the deposited portion.
5) After repair has been completed, measure the
resistance in repaired wire.
