It has a single switch instead of a split-type master switch like you see in Cessnas. With no Alternator Field switch, are there times with a Z-12 system when one might wish for a split switch, or two seperate switches? How is this system different from the electrical systems on most factory-built aircraft that separate the functions? Thanks in advance for educating me.

The S700-2-10 switch (B&C p/n) shown in the Z-figures is a progressive transfer switch that emulates the split rocker used on many type certificated single-engine airplanes. See chapter on switches in the 'Connection Alternatively, one may consider a simple double pole, double throw switch to bring battery and field on together. In this case, pulling the breaker (required for crowbar ov protection system) disables the alternator field path when the DC power switch is on for extended periods of time with the engine not running.

Most or all of them can be seen in a blue font. It won't be for several weeks before I'll need to finalize the starting wiring, so I'll have the chance to get more feedback about the 2- versus 3-switch starting circuit. As drawn, I still have the 2-switch version. I may decide to stay with the Powerlet sockets for the cabin aux power, but since they wouldn't be used for more than a few amps, I could get a more standard cigarette socket. This one http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=AS212-ND has a locking mechanism. Looks like you'd just twist it when you slide the plug in. They also sell the locking plug. Digikey told me the socket accepts any cigarette plug, but it's not clear to me if they all would lock. For the batter charger connection that I'd mount FWF and access through a cowl opening, I found a few kinds that seem like they'd work. The first one below is has an SAE on one end and Anderson powerpole on the other. Never heard of Anderson before, but sounds like they are popular in the RC arena: http://www.powerwerx.com/adapter-extension-cables/bullet-connector-to-powerpole.html Another one used by RC are Deans Ultra Plugs: http://www.wsdeans.com/products/plugs/ultra_plug.html I would think any of these connectors would have no problem carrying 10-15 amps from a charger. -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=259310#259310 Attachments: http://forums.matronics.com//files/dans_z16m_mod_2_for_jabiru_3300_sonex_114.pdf ________________________________ Message 4 _____________________________________ Time: 07:48:03 PM PST US Subject: AeroElectric-List: Audio Alert to PM 100II From: "Don McIntosh" I have a Dynon D180 that has 2 audio alert outputs that I can tie together but there is no Aux input on the PM 1000II intercom or my Garmin SL 40 to hook to. Someone said to hook it to my phone (headphone?) output but when I called PS Engineering, they weren't sure it would work and had no suggestions except that their new PM 3000 has 2 Aux inputs. Any ideas on how to get audio alert from my Dynon? I do hate to undo my existing pins and soldered shields. I have an "expansion unit" input slot that is open on the intercom harness, that is apparently used for attaching their unit to add up to six passengers. -------- Don McIntosh Kitfox Series 7 under construction Jabiru 3300 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=259415#259415 ________________________________ Message 5 _____________________________________ Time: 10:21:29 PM PST US From: "Vern Little" Subject: Re: AeroElectric-List: Audio Alert to PM 100II Hi Don. What you need is an audio mixer. The one that we manufacture is the AMX-2A at www.vx-aviation.com. It takes 10 inputs (4 variable), which may be overkill, but it will work with any radio and intercom, even ones that do not have auxiliary inputs. The variable inputs are ideal for the Dynon D180. Some rewiring is necessary, but the unit is extremely small and can be buried in the wiring harness.
