Rearrange the power plug
connection correctly.
Is there AC 100V behind
the fuses F1 and F2?
Fuses F1 and F2 have blown
out. Replace the fuses. If they
blow out again, the POWER
unit is out of order
Is there M+14V output at
Pin 1 of the PM connector?
Disconnect the PM and PQ
connectors from one after
another. If there is M+14V
output, the circuit beyond the
connec
tors is out of order.
If there is no
output, the
POWER unit is out of order.
Is there +5V output at Pin 2
of IC6805 (ANALOG module)?
