Quick question, and I know this has been covered before...BUT:Should the shield of the shielded wire from the mags to the switches be groundedon BOTH ENDS, or ONLY ONE END; and if one end, WHICH END? Or does it reallymatter?Thanks,Ray KrauseStill working on SkyScoutSent from my iPad________________________________________________________________________________

RayGround it at the Mag end only . If yoy ground it at both ends it will set up edy curents and cause more noise.Dale----- Original Message -----

Mine are not grounded at the switch either. I clipped off the braid at that endand then used a little heat-shrink tubing to cover that part of the wire. Ihad heard the same thing about the possibility of circular currents. I havenot yet had a chance to operate my handheld in the cockpit to see if the groundingscheme and shielded harness have taken care of ignition noise, but I'll soonfind out.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 28 Apr 2014 14:05:48 -0700 (PDT)
