FLOW CHART NO.6
AL+44V is not outputted.
Is the supply voltage 44V fed to the cathode of D013?
Check D013, D1140 and their periphery, and
service it
if defective.
Check for short-circuiting or leak on the load circuit,
and service it if defective.
FLOW CHART NO.8

Is the supply voltage 12V fed to the cathode of D014?
Check D014 and their periphery, and
service it if
defective.
Check for short-circuiting or leak on the load circuit,
and service it if defective.
