Well, I'm putting this one away. When checking for a ground, found wire out of terminal feeding rem, which was off-line but what the hell, put it back, fired up rem( w/out Otis line worked for a week). Same s>>t. punched all wires in COP. good for two days!!!!. Well lo and behold, bad DZ switch out of the box, intermittent at best. One of the first places I went, WTF.... Running for three weeks now. I would like to thank all for your input, and El, I never went back to the (NEW) switches, Why right.
