Hi John,
I've been unsuccessful in testing them with a "plain" ohmeter. I
suspect there are several discrete diodes in series inside, and the low
battery voltage of an ohmeter is not high enough to make the string
conduct.
I expect it'd be possible to get a good idea by using a variable DC low
voltage source, with a current limiting resistor and milli-ammeter in
series. Conduction should occur at less than 20 vdc in the forward
direction, and be minimal in the reverse direction.
