Bingo. Good find. As long as a common ground doesn't prove problematic, you won't find a simpler/cheaper solution. Those terminal strips are particularly friendly for terminating stranded wire . . . they have a flat surface that is driven down onto the strands as opposed to the end of a screw. Vibratory forces are not transferred from wire to screw. Thread locking is not necessary. However, they do lack wire support. expose minimum length of strands so that insulation tucks up tight to terminal strip body. Dab of E6000 will take care of the vibrational-flexing issue. Those regulator assemblies are well populated with capacitors that go to noise issues. They might well be quieter than a battery. Bet you didn't know that batteries generate noise . . . exceedingly tiny but not zero. Bob . . . Un impeachable logic: George Carlin asked, "If black boxes survive crashes, why don't they make the whole airplane out of that stuff?" ------------------------------------------------------------------------------------- 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.
