If voltage is present, the ionizer is OK. Clean needle with alcohol and a cotton swab. b. If voltage is not present, check HV power supply. See above diagram. c. If voltage is present at HV power supply but not the needle. Replace the negative ionizer assembly including wire, with needle attached, and terminal.
