Touch-buttons that sense body capacity can be really twitchy in the presence of strong RF. Can you send me a wiring diagram for your lighting control system? I must admit that I'm not optimistic but we can try. Need to see the installation manual and wiring.

It was easy and worth a shot. Thanks for trying. With the com off there's no problem with the EB. There's a 15' parallel run of speaker and EB wiring and that's where the problem is. When I run non-parallel wiring to power the EB, the problem disappears. Soo...see below. Bob, Thank you for your willingness to give it a go, but I've decided that the simplest fix is to re-route the wires to the EB. I didn't want to do that because it means pulling out some nice upholstery work to get 2 x 22 ga wires underneath it. But I know from experimentation that it will work. That's going to be the best use of both yours and my time.;-) Cheers, John Read this topic online here: http://forums.matronics.com/viewtopic.php?p=366897#366897 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
