There's a LOT of words here . . . some of which are conflicting. It's going to take awhile to do an analysis. In he mean time, tell us about your airplane. Is it wired per any of the z-figures? What's your bus voltage run in flight? Your failure rate is too high to blame on a working maintainer of any brand. Have you measured the maintenance voltage of your maintainer? As often as you appear to be flying, there's no driving concerns for using a maintainer at all. I'm thinking something else is going on with your system that's generating these battery failures. Check that regulator setpoint.

At this point, I plan to not use the maintainer and fly often enough to keep the system going. I will test the maintainer on an old battery and see what voltages I get. john ------------------------------------------------------------------------------------- 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.
