MAINTENANCE
SYMPTOM
PROCEDURE
Low output voltage on J801.
0 < Vo < 12.5 VDC
Check the following:
1. If one of the dual diodes on D1, D2, D3, or
D4 is shorted.
NOTE
: All four diode packages contain two
diodes each.
2. Line frequency < 50 Hz.
3. Load current greater than 3.0 amps.
High output voltage on F801A
(>30.0 VDC) or J801 (>16.3 VDC).
Check the following:
1. R1 not connected between pos. 1 and 2 on
F801A.
2. R2 not connected between pos. 1 and 4 on
J801.
3. Line frequency >50 Hz.
