7. For the single door models,
check that the two blue wires
terminals J10 and J12 are con-
nected together as shown by
Figure 11.53.
8. With the volt-ohm-meter set
to measure 12 volts DC,
check for 12 volts at the emit-
ter of transistor Q2 as shown
in Figure 11.54.
A. If you do not have 11-12
volts as shown, connect
J10 and J12 together as
shown in Figure 11.53. (2
door models only)
B. If you now have 11-12
volts at the emitter of Q2
there is an open circuit in
the harness to the Humid-
ity/Storage switch and it
must be repaired (See wir-
ing pictorial at the back of
this section.).
9. Set the Mode Selector
switch to DC-ON. The DC
light on the Eyebrow should
be illuminated.
10. If the DC light is not illumi-
nated you must do some more
tests to find the problem.
11. With the Mode Selector at DC-
ON and 12 Volts present at the
emitter of Q2, check for 10
volts DC at the base of transis-
tor Q2 on the Power Supply as
shown by Figure 11.55. If you
do not have 10 volts, the
Power Supply is defective and
must be replaced.
