(c) Measure the voltage at the center of each defogger wire as shown in the illustration.
Standard Voltage:

Criteria |
---|---|
Approximately 5 V |
Wire is not broken |
Approximately 10 or 0 V |
Wire is broken |
*a |
Ground Side |
*b |
Foil Strip |
*c |
Approximately 10 V |
*d |
0 V |
*e |
Broken Wire |
*f |
Battery Side |
HINT:
If there is approximately 10 V, the wire may be faulty between the center of the wire and the wire end on the battery side. If there is no voltage, the wire may be faulty between the center of the wire end and the wire end on the ground side.
(d) Place the voltmeter's positive (+) lead against the defogger wire on the battery side.
(e) Place the voltmeter's negative (-) lead with the foil strip against the wire on the ground side.
(f) Slide the positive (+) lead from the battery side to the ground side.
(g) The point where the voltage drops from approximately 10 V to 0 V is where the defogger wire is broken.
HINT:
If the defogger wire is not broken, the voltmeter indicates 0 V at the positive (+) end of the defogger wire and gradually increases to approximately 12 V as the meter probe moves to the other end.
