I remember reading sometime back about a proposed alternative to the Z-19 dual battery design. Is there one that has still not been published in the book? Thanks Hari Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465280#465280 ________________________________ Message 4 _____________________________________ Time: 04:35:23 PM PST US From: William Greenley Subject: AeroElectric-List: Headset jacks wiring Will be having 4 sets of headset jacks in a console between the front seats in my RV-10. I would like to make the console removeable. Would it create an interferance problem if I use a molex connector or something comprable to serve as a disconnect. The shield would be connected to a pin so it would carry through the connector. ________________________________ Message 5 _____________________________________ Time: 05:53:04 PM PST US From: Sebastien Subject: Re: AeroElectric-List: Headset jacks wiring Wouldn't it be easier to leave 2 extra feet of wire coiled up so that when you remove the panel you can just put it aside?

I don't have the same confidence in molex connectors, though.

You get rid of starter relay, but you have to replace standard aviation mag/starter switch with one that will carry 30 amps of current, or roughly 360 watts.

If I wanted to add a starter engaged light connected to "I" while using that terminal to engage the starter solenoid would it work to place a good sized resistor in series with the lamp? dave Read this topic online here: http://forums.matronics.com/viewtopic.php?p=465297#465297 ------------------------------------------------------------------------------------- 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.
