See the identification of Power
Supply versions below.
2. On the second version of the
Power Supply board, the stor-
age switch and the trans-
former were removed. When
this occurred, a 12 Volt DC
supply was required for opera-
tion in all modes.
Note:
On refrigerators with the "second
version" Power Supply board, the
12 volt DC must be disconnected
from the Power Supply board to
eliminate a constant current draw
of 15 to 20 milliamps. Failure to
disconnect the 12 volt DC, (during
times which refrigerator is not in
use (storage), can cause battery
run down.
See the identification of Power
Supply versions below.
3. On the third version of the
Power Supply board 12 volt
DC must be supplied in order
for the refrigerator to operate
in any mode. The "storage
switch" was added back to the
board but the switch itself will
not totally eliminate the 12 volt
DC to the refrigerator when in
the OFF (up) position.
Note:
The storage switch will eliminate
current to the interior light and
HIGH HUMIDITY circuit only. To
eliminate current draw, turn the
storage switch and the Mode Se-
lector switch to the OFF position.
For added protection against bat-
tery run down, disconnect the 12
volt DC from the Power Supply
board.

Supply versions below.
