I will post to the list when I'm ready to accept orders. Bob, The premade harness sounds like a good deal. I had mine done by Tracy once I realized that getting all those tiny pin solder connections right was beyond my capability. One thing to consider is that with a canard pusher you can't get a prewired harness installed easily because the plugs won't go down the electrical conduit. A harness could be installed during the fuselage construction, but once the fuselage is built you either have to run the harness another way, add a connector, or snip and resolder all the wires. As for my "troubles", I beginning to think that these had nothing to do with the EC2 wiring. I think what happened to me was a combination of lack of expertise and being in South Florida. I followed Bob Nuckoll's teachings and used crimp connections. The crimps (at least when done by me) allow humid air to get in the ends. My wiring worked fine 2 years ago when I installed it. Two years of humid salt air and a bit of vibration has gradually degraded important connections and created nasty gizmo eating ground loops. I'm now working to clean up the connections with heat-shrink soldered joins and double heat-shrinked soldered crimps to fast-ons etc. etc. I'm working "top-down", as Tracy puts it, going after the high current circuits first, testing the resistance under load as I go, and making sure the connections are air-tight. You live and learn. :) Regards, John (Have soldering iron - will travel (eventually)
