    I was wanting to disable the copilots transmit function when the pilots ptt was activated & disabling the pilots transmit function when the copilots ptt was activated. 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. Thanks for the replies Eugene Pilipanko Read this topic online here: http://forums.matronics.com/viewtopic.php?p=449747#449747

    Here is a link to a wiring diagram showing how MicroAir uses two relays to connect the mics. http://tinyurl.com/Microair-PTT Eugene, are you going to use the intercom function of the radio? -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=449750#449750

    I was planning on using the intercom feature. 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. Eugene Pilipanko Read this topic online here: http://forums.matronics.com/viewtopic.php?p=449753#449753

    From: "jrevens" <jrevens@comcast.net>
    This may be a dumb question, but would using a shielded twisted pair for the combined ignition control wiring to both modules be OK, or are 2 individual shielded single conductor wires preferred for some reason? I am basically using Bob's Z-16 diagram... I am very grateful to have that, Bob! -------- John Evens Thorp T-18 N71JE (built &amp; flying) Kitfox SS7 N27JE (building) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=449754#449754

    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
