So is the -2450 TP actually at -1890? I thought that you had quoted a quoted a much different reading in an earlier post. If the HV multiplier was bad, I would not expect that -1890V reading. To be sure, I would still disconnect the Ground lead to entirely eliminate the possibility of a bad HV Multiplier.
