Although the original diode appears to be open, two other diodes I have (right out of the factory sealed package) both also test open (in both directions). Since my meters will see the forward voltage higher than 2 volts, this HV diode cannot be checked on them. My three meters will all check smaller diodes and bridge rectifiers (1N4004, 1N4007, Vishay GBPC606-E4) with no problem (which does me absolutely no good in this case), and I've verified all three meters are working accurately.

I've also got a vintage Simpson meter (non-digital) around here somewhere, but haven't been able to locate it. Hopefully, my wife didn't take it to the Goodwill store with my o-scope that only needed a new probe.

As I initially mentioned, note that I have used one of the new replacement HV diodes with the same results; as well as a new HV cap.
