Hi Richard,

Can you tell me the technical explanation (in an "Idiot's guide to" 
method) as
to why a conventional diode tester (that shows .6xx voltage across an 
ordinary
silicon diode) will not show any indication across these diodes? Are 
they not
just plain old standard diodes? What's inside the modules? Just 
curious... and
I bet you've "been there, done that"?

Thanks, -Web
