Hi Dan, Since there is just as much current flowing through the ground wire as the positive wire, it is possible for it to heat up as well. -Dj -- Dj Merrill - N1JOV Glastar Sportsman 2+2 Builder #7118 N421DJ - http://deej.net/sportsman/ Grumman Yankee Driver N9870L - http://deej.net/yankee/ ________________________________ Message 2 _____________________________________ Time: 08:40:10 AM PST US From: "Robert L.

Use of solid wire is contrary to accepted practice in all manner of vehicle. It's recommended for stationary applications only. Where is your panel ground bus located? Is it mounted on or close to some panel support structure that is not subject to periodic removal from the airplane?

My panel ground is located on the under side of the permanantly mounted glare shield. It's a few inches away from the main buss block, whose piano hinge sections can be seen in the pic. Regarding the panel ground buss, I have used a section of the B&C forest of tabs. It would be convenient to rivet the brass block to the glare shield and use one of the tabs to connect to the firewall. Would using a faston for 10awg wire here be okay, or would it be better to solder it, or both? I'd rather not have an ugly bolt head on top of the glare shield. If I solder without the female faston, would I just drill a hole in one of the tabs big enough for the bare wire to go through and solder it like that? If soldering isn't as good as a ring to bolt connection, I'd prolly make a little standoff bracket for the panel ground. -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=272920#272920 Attachments: http://forums.matronics.com//files/subpanel_progress2_207.jpg http://forums.matronics.com//files/ground_buss_and_cig_lighter_184.jpg ------------------------------------------------------------------------------------- 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.
