Okay, WHY heavy duty? This switch normally carries less than 5A for the alternator field and 1A for the battery contactor. Since you're not attempting to eliminate the battery contactor with a manual switch, I'm mystified by the notion that trading out the two pole master for a single pole device is a good thing to do . . . Ok, so if I'm reading you right, since the battery lead on the alt and the field lead are both connected to the main power bus, the residual magnetism in the alternator could cause it to produce some bias (voltage) that will keep the field coil working, which creates more bias causing it to continue to work. Did I get that right? Yes, that is the essence of "self excitation" . . . generators did it nicely, alternators often do not come on line by themselves but will run without a battery once they get stood up. I wonder what happened to my attachment, I got it. Oh well, you can see it here: http://forum.matronics.com/viewtopic.php?t=67973 Anyway, no I'm not looking to replace the battery contactor. Okay. That leads me to inquire as to the design goals for departure from the legacy control philosophy for a DC power master switch in aircraft. No, I just like the switch (it's a push/pull), and it just happens to be high current, I'll still use the contactor. If it's just a style-thing, I'll suggest you reconsider and go with Z-11 (or other architecture) as published.

The engine kept running, which proved to me that the alternator was working OK. As for your proposed circuit, it looks like it will work OK. The only issue that I see is that a hot wire will be brought into the cockpit with no way to shut it off. That wire should be double insulated and protected with a fuse near the battery. You could use a relay near the battery to eliminate the hot wire into the cockpit. That introduces another failure point, which is OK as long as you have a backup plan. Can you manually trip that 5amp breaker? Is there some failure mode where it is desired to shut off the alternator without shutting off the master contactor?

Roger ________________________________ Message 5 _____________________________________ Time: 08:13:14 AM PST US Subject: AeroElectric-List: Re: Z-13/8 modification (version 2.0) From: "user9253" Lincoln, The dynamo relay has a missing diode from the N.O. terminal to the coil. This diode allows the relay to be energized from the dynamo power even if the battery and main alternator are completely dead. If you do not want to use this diode, then the other diode that connects to the COM terminal is not needed either, although it does not hurt anything. Either both diodes should be used, or none at all. Using two diodes allows the dynamo relay to be powered by two separate sources without connecting those two sources together until the dynamo relay contacts are closed.

Dick Hi Dick, Either you are getting a bit confused or you are looking at different websites than I am. I have ordered a pair (2) Folding cup holders through Scottlandyardspares.com for a grand total of $11.50 postage paid. When I looked at the ebay site I found the same thing for $9.95 + $5.95 shipping, or $14.99 with free shipping. Am I missing something??

New member here. I just bought the Revision 11 book at a reduced price. I am building a simple (electrically) airplane and had hoped to use the diagram Z-11 as a basis for design. Alas it is not in the book. The first drawing in the Z section is on the back of page Z11 but it is Z-12 for a dual alternator. What gives? I understood that I could upgrade my book on line with the newer stuff and maybe the drawing is available there, but I can't find that link. ------------------------------------------------------------------------------------- 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.
