Measuring Power Supply Output, Compressor Disconnected
A cAUTION!
Do
not use a converter or battery charger
to
supply
DC
power
to
the refrigerator. These devices
do
not
supply filtered
DC power. When Using a converter
or battery charger, make sure
that
a battery is
connected
in-line between them.
1.
Connect the DC power supply to a charged 12 volt
automotive battery.
Observe the correct polarity
(red+/
black-)
when connecting the DC Power Supply wires to
the battery.
2.
Disconnect the line voltage wire from the compressor.
3.
Tum on the refrigerator. The power light should illuminate.
4.
Measure voltage output at line voltage connector. See
Figure 14. Voltage values with the compressor
disconnected:

17 to 25 Vac.
17 to 25 Vac.
The DC power supply must be replaced
if
the voltage output
is not within the specified
values.
5. Shift operation to
AC
power. Plugging the
ACcord
to a
"live" 120 Vac outlet will automatically shift refrigerator to
AC operation.
6. Measure
voltage at compressor. See Figure 14, See step
4 for voltage output
values.
No voltage! or voltage is lower or higher than values listed in
Step 4,see Procedure D, page
11.
