2. Power Supply Volume
With all the wiring removed, check unit power board.
(1) Remove all flat wires and wire assemblies which are connected to CN971,CN972,CN951,CN952,CN981.
(2) Short -circuit CN951 "1" (POWER ON:B9006) and "2" (B5V:B9019). (Set each regulator to ON.)
(3)
(4) Connect to the outlet and check the voltage at each part.
(For the voltage specification, see the standard schematic diagrams.)
Then restore the connection of CN971,CN972,CN951,CN952,CN981 and check voltage.
(1) Remove the wire short -circuiting CN951 "1" and "2".
(2) Remove the load resistance.
(3) Restore the connection of CN971,CN972,CN951,CN952,CN981.
(4) Connect to the outlet.
(5) Turn the POWER switch on and check the voltage at each part.
If voltage abnormally drops when CN971,CN972,CN951,CN952,CN981 are connected (load is connected)
though the voltage was at the normal level when CN971,CN972,CN951,CN952,CN981 were disconnected
(load is connected), or if the protective element (fuse, etc.) is opened, the load which is supplied power may
be defective or the wiring may be short-circuited.
The load resistance is connected between CN961 "4" (D5V:B9008) and "3,4"(D.GND:B9001).
* If the load resistance is not connected, the voltage is not output to "B9008".
