(Dj Merrill) ________________________________ Message 1 _____________________________________ Time: 09:53:31 AM PST US From: Subject: AeroElectric-List: a simulator mode 4/2/2009 Hello Old Bob, Apparently the Garmin 400 and 500 series GPS units do not include a simulator mode. I found the term "demo mode" in my 430W manual, but no words at all on what it was.

From: "tx_jayhawk" Bob, There was a question that a few of us were debating and would be interested in your input on. Assuming you have a single battery installation and a good (regulated) alternator doing its thing as expected (putting out 13.8ish volts), what would be the effect on the system if the battery was disconnected (like if primary battery cable came undone or was disconnected)? I know the battery acts like a capacitor to dampen the bus voltage (and fluctuations from the alternator), but would the alternator continue to output the right voltage in the quantity (current) as dictated by the active loads on the bus? In other words, could you fly indefinitely as long as the active load did not exceed the alternator capacity (and assuming the regulator was working appropriately)?

The car ran fine until the headlights were turned on, then it ran very rough, then fine again once I turned the lights off. I drove it several miles to a place where I could replace the battery terminal. -Dj -- Dj Merrill - N1JOV Glastar Sportsman 2+2 Builder #7118 N421DJ http://deej.net/sportsman/ "Many things that are unexplainable happen during the construction of an airplane." --Dave Prizio, 30 Aug 2005 ------------------------------------------------------------------------------------- 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.
