In case there are some out there considering strobe power supplies for their RV10, here are some diagrams that may be of interest. Here is (hopefully) a link to a page of the instructions for the old CreativAir Avi-pak strobe power supply. I don't think these are sold any longer but I'm sure a number of older RV10s have them. https://www.dropbox.com/s/2mz34v7tidnmbah/AVI-PAK%20from%20CreativAir.jpg Here is a link to a page from the non-aviation supply from Nova Electronics where the switch is in some kind of control circuit. https://www.dropbox.com/s/vfsm8htq7e82upx/XPAK604X%20scan.jpg Given the typical locations in the RV10, Wiring the main power line to a power bus location that is local to the battery seems preferable to running the same power line up to the panel and back.

When I looked at your diagram, for some reason that symbol seemed backwards. But I looked at my own diagrams and they are the same as yours! iDennis ------------------------------------------------------------------------------------- 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.
