The theory is that if the feeder shorts to sheet metal, then the sheet metal will burn away before the feeder burns in two. The most likely place for the feeder to short out is where it passes through the firewall. If properly installed, then that will not happen. As for a battery bus, adding a fuse is likely to cause a problem, not eliminate one. There are 3 possible locations for an ammeter: alternator output, battery current, or aircraft load. Each location has its advantages and disadvantages. There has been much debate about which location is best. It is a matter of personal preference. No matter which location is chosen, the important thing is for the pilot to understand what the ammeter is displaying. For example, suppose the builder installs the ammeter to measure aircraft load. The aircraft is then sold. While on a cross country trip, the new owner notices that the voltage is low. He is not concerned because the ammeter is showing normal current. He does not realize that the alternator has failed and the battery is running down. Actually an ammeter is not a necessity. A voltmeter will tell the condition of the electrical system. If the voltage drops much below 14, something is wrong. Do the troubleshooting on the ground. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=478231#478231 ------------------------------------------------------------------------------------- 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.
