HINT:
If there is approximately 10 V, the wire is broken somewhere be-
tween the center of the wire and the positive (+) end. If there is
no voltage, the wire is broken somewhere between the center
of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
positive (+) terminal.
(e) Place the voltmeter negative (−) lead with the foil strip
against the heat wire at the positive (+) terminal end, and
slide it toward the negative (−) terminal end.
(f) The point where the voltmeter deflects from zero to sever-
al V is the place where the heat wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but gradually increases to about
12 V as the meter probe is moved to the other end.
