If the voltage is 10 V, it means that open wire exists be-
tween the center of the wire and the end of the positive
: side. If the voltage is 0 V, it means that open wire ex-
ists between the center of the wire and the end of the
earth side.
Locating point of open wire
1. Connect the positive : terminal of the voltmeter to the
positive : side of the defogger wire.
2. Slide the voltmeter's negative ; terminal wrapped with foil
strip on the defogger wire from its positive : side to its
negative ; side.
3. The voltmeter reading changes from 0 V to several volts at
the point where open wire exists.
Repairing point of open wire

2. Affix masking tapes to both upper and lower portions of
the point to be repaired.
3. Stir repair agent (Du Pont Paste No. 4817) thoroughly.
Apply a small amount of the repair agent to the repairing
point, using a fine brush.
4. Two to three minutes later, peel off the masking tapes.
5. Do not energize the defogger wire within 24 hours after
the repair.
