The gauge is capable of displaying rpm as well. Since there is a single wire to from the unit (for rpm) I would think it is impossible to show the rpm on both mags as well as individually during a mag check. I can connect to the P-lead of either mag and get an indication but it is only for that mag of course. Am I missing something.....

If you get a different reading from two mags, both of which are connected to the same camshaft, you're not measuring RPM, you're checking for a bad mag. You could put a double throw switch in the line. -- --> A fair tax is one that you pay but I don't <-- ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message avionics-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Avionics-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/avionics-list Browse Digests http://www.matronics.com/digest/avionics-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.
