Remove it. Repurpose that 40 amp fuse to protect the electrical system from a shorted alternator or its "B" lead. Or use a fuselink. Good workmanship will prevent the engine busbar from shorting out. Relocate the engine Fuses. They should be between the busbar and the switches. The 60 amp fuse is not needed. Eliminate it. I suggest that you use battery contactor in series with the aircraft main power bus (not to be confused with the engine bus). There should be a fuse between the engine busbar and the start push button. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=505388#505388 ------------------------------------------------------------------------------------- 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.
