BODY ELECTRICAL SYSTEM
(d) Place the voltmeter positive (+) lead against the def–
ogger 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
several 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.

silicone remover.
