 Hello to everybody, does anyone have the best diagram for installing the dual EFII, with two alternators and single battery??

 And second question, how would be the wiring with the bus manager using 2 alt and single battery 	


  It would help to know what airplane you're building

  and the engine you selected. Also, how do you intend

  to use this airplane?  Mostly day, VMC fun trips? Any

  long cross country over sparsely populated terrain, mountains,

  at night? Any IMC ops anticipated?

Hello my friends, thanks for the answers.

Here I give more details so you can help me with my wiring...

I’m building an RV-7, it is in the final process, I have just hang the engine, an Aerosport Power WildCat IO382; with full FlyEFII ignition and injection system, and dual Ecu’s. My avionics are one garmin G3X touch and Autopilot.

I wanted an aircraft with dual Alternator and initially single battery, dual alternator just because I’m going to fly in Patagonia Argentina, and here there are not much runways, and initially only one battery because I don’t want too much weight, don’t want to waste money in a second battery, don’t want more complexity, and in my point of view I consider batteries super confident, I have never had a battery failure, but I have had an alternator failure 3 times in my life, 1 in the car and 2 in the aircraft... so I prefer 2 alternator, and one odyssey battery... may be later if I desire to make a very long flight, or a very difficult flight like going to the Antartica, then I would consider going there with 2 batteries and 2 alternators, but not know... first I have to put this machine in the air...

Said all this, I saw AeroElectric book and the Z-12 diagram. And I already have all the components of that figure I bought everything in B&C, including the stand by alternator for the vacuum pump (40 amps).

My question is if this diagram would work with my dual Ecu’s EFII, how would I need to modify this, does anybody have a picture of the distribution of the components into the aircraft, and the switches in the cockpit??

All you can show me to clarify my ideas is very welcome...

I'm considering the Z-12 as well for a SDS EM-5 FFI system in my RV-8.  I found this on another popular forum.  The link can be found below.

Thanks!

Do you have this diagram in better quality? It can’t see very well..

Bob, or anybody else to help how to wire a dual EFII, into the Z-12 diagram...?

Thanks!

Hello my friends, thanks for the answers.

 Here I give more details so you can help me with my wiring...

 I'm building an RV-7, it is in the final process, I have just hang the engine, an Aerosport Power WildCat IO382; with full FlyEFII ignition and injection system, and dual Ecus.



 I consider batteries super confident, I have never had a battery failure, but I have had an alternator failure 3 times in my life, 1 in the car and 2 in the aircraft... so I prefer 2 alternator, and one odyssey battery.



    Generally speaking, B&C alternators are

    exceedingly long service lived. Failure

    rates are a tiny fraction of the fielded

    product. Most failures are due to installation

    error or external influences.



    A JUDICIOUSLY maintained battery is the

    single most reliable source of electrical

    energy in the airplane. A maintained battery

    simply doesn't fail in flight. When maintained

    batteries become unavailable in flight, it's

    a result of effects external to the battery.



 .. may be later if I desire to make a very long flight, or a very difficult flight like going to the Antartica, then I would consider going there with 2 batteries and 2 alternators, but not know... first I have to put this machine in the air...



    With two alternators, the battery(ies)

    are no longer tasked with alternator-out

    endurance duties, hence they may be selected

    primarily for their ability to crank the

    engine and offer some stability to alternator

    performance.



 Said all this, I saw AeroElectric book and the Z-12 diagram. And I already have all the components of that figure I bought everything in B&C, including the stand by alternator for the vacuum pump (40 amps).



    The pad mounted alternator is fabricated from

    a 40A core . . . but if your pad is the

    legacy gear ratio to the crankshaft, then

    cruise rpm at the pad is on the order of 3700-

    3800 rpm . . . too low to realize the machine's

    full 40A output.



 My question is if this diagram would work with my dual Ecu's EFII, how would I need to modify this, does anybody have a picture of the distribution of the components into the aircraft, and the switches in the cockpit??



   Is there a down-loadable installer's manual

   for your engine? It's difficult, if not

   foolish, to make recommendations without

   knowing the requirements/recommendations

   for all ship's electrical components, not

   the least of which is your engine.
