Some hv diodes consist of several 1kv diodes in series. If there were four
then it would require a voltage of about 2.8 volts for all of them to conduct.
Many Volt Ohm Meters use a 1.5v battery for the low ohms scales and in this
case is not enough for conduction. If the meter has a higher voltage for
higher ranges, you might see conduction.
You can also connect the diode under test in series with a resistor and use
your 13.8vdc shack power supply as a higher voltage current source. If you
used a 1k resistor, you would expect to see about 11ma or so in the forward
direction and hopefully zero ma in the reverse direction.

Anybody familiar with the RCA CR104 4000PIV rectifier. I am not getting any
continuity either way. Six out of six NC. Just using a basic multimeter.
