Problem:
Dim flash on "Flash Gordon" strobe
unit.
Cause:
Open capacitor (C2) 22ufd 250vdc.
(See figure 1 below.)
Procedure:
With an ohmmeter on xlOO scale,
measure across C 2 to see if it discharges
and charges by alternately reversing
the leads. Ifno action, do the same to
C3 and you'll see the difference. As of
now I have not seen C 3 go bad; only
C2. But I'm sure it can. Either way,
you can use this test by comparing
meter readings vice-versa.
