What in the world is a zenner diode??? I guess I am also not very smart with my wiring but still enjoy doing it. A diode just lets electric flow one direction if you need to know like a flapper valve.
Yes, what is a zenner diode reynoldston? You and bertsmobile1, motoman, ILENGINE, and others have been very helpful. bertsmobile1 is the only one that mentioned that I may have fried the modules. I was trying to find out if I did fry them. Two cost over $200 and I was trying to avoid having to buy them if I could find out if mine were still good. Any thoughts? Thanks for answering.
