[time-nuts] 5062C trouble

[Corby Dawson]

Tim,

The ion pump supply should be on if the unit is plugged in and on.

Remove the HV connector from the supply to remove any load and measure
the divided test point on the bottom of the chassis.

It should read between 2.45 and 3.0 VDC, if not measure from pin 4 of the
ion pump supply to ground. You should have 19VDC.

If HV is good with connector removed and bad with it on, the ion pump is
most likely shorted. If the 19VDC is bad then the regulator between the
+50VDC and the ion pump module is bad. Depends if you have an option 10
or not how it's hooked up but you should be able to trace it.
