Dale,

I was trying to say that my real surprise was the continuity between Blue & Red and the fact I got 12v on Blue. I was expecting, as you stated that Blue & Black would be the same (common or ground). From what I saw it was Blue & Red that were the same and Blue was 12v. That's really got me confused?

The one I have had hooked up for a while is wired just like your drawing, except I have Blue on Common. Could have been your drawing I used for original hookup? I have followed your posts and drawings and learned a lot about model RR wiring. I also like relay logic. Thanks for sharing your knowledge with us!

FWIW again... After some more fiddling, Black on relay Common works the gate just as well as Blue (as stated in your post), but there was still 12v on Blue the whole time, and nothing on Black? Although tempted, I was afraid to touch Black & Blue together for fear of smoke. Something odd here.
