Hi Jim,
In the last 20 years I've heard a lot of talk about diodes (and
other devices) failing intermittently. I have yet however, to ever
see a semiconductor that was anything in between good, and bad. They
either fail from too much voltage, or too much current, or too much heat. ....
I am open to the benefit of experience from others, but I have
spent literally hundreds of hours in the field investigating claims
of power semiconductors that would intermittently fail, or only fail
at high current or voltage. I can definitively say that I have yet
to ever fail to find other problems that were directly responsible.
... So for my 2.5 cents worth check them with a multimeter, and then
install them.
Cheers,
Leigh
