First off I want to thank all that took the time to reply. I am a idiot. Like I said both signals worked fine when not tied together, so I didn’t think anything was wrong with either signal. I went back to check the power wiring and sure enough I had reversed hot and common on one of the boards. That did not prevent it from working independently, but when tied together with the other signal all went south. Wired it correctly and all works as at should. Again I thank all of you for your input and patience with me.
Thanks,
Ed
