Jim, The ion pump supply is fine if the Cs oven reading is OK. A zero reading is fine on the Ion pump current.
Yes do check the ionizer filament continuity and if its OK check the voltage across it. Should be around 1 VDC. If all that looks good pull J1 off A7 and feed it into a high impedance voltmeter and redo the low freq. test. If it looks good You might have a bad A7.
