What I am trying to accomplish is not have both mics on when only one ptt is activated. The flightline wiring diagram lists a isolation relay board which is no longer available.

I am trying to get some information on how to wire the unit before I install it. It will be couple of months before I will do the installation.

I am basically using Bob's Z-16 diagram... I am very grateful to have that, Bob! -------- John Evens Thorp T-18 N71JE (built & flying) Kitfox SS7 N27JE (building) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=449754#449754 ________________________________ Message 5 _____________________________________ Time: 07:47:27 PM PST US Subject: AeroElectric-List: Re: Rotax ignition wiring From: "user9253" It is better to have individual wires for each ignition to prevent one electrical problem from disabling both ignitions. The shield on each ignition wire (on my Rotax powered RV-12) is separated in the middle. The shield is grounded at each end. I suspect that Van's designed it that way to prevent starter current from burning open the shield if the engine ground wire ever breaks. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=449755#449755 ------------------------------------------------------------------------------------- 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.
