the failure, then after a week or a month, it works again for a while?
Ron Intermittent. Take one apart. Got VOM ? Greg

Not these days-- a sad story I wont bore you with. But if I had one, what
would I be looking for? It's pretty certain that I'll buy one again, and
it won't last any longer than an ice cube on a hot day. :-)

Continuity. You should also hear clicking using a meter. Lightly pushing
around the mic element might make the connection good for some instant, or
it might temporally fix itself. Put leads on connector while doing this,
and also watch meter.
I would rather use an analog meter. The wires on the mic are very small.
