Is there a simplified schematic available for Z-13/8 that utilizes the always present battery to energize the SD-8?  

   

Thanks,

   Not sure I understand "simplified" or "energize".

   The latest configuration is here:



http://www.aeroelectric.com/PPS/Adobe_Architecture_Pdfs/Z13-8Q.pdf



   The extra diodes and resistors in the SD-8 wiring

   along with diodes on the alternator disconnect

   relay will use the battery to jump start the SD-8.

   Is there some additional functional feature you

   need?

Bob,  

   

I believe I should have used the term SD8 “self excitation”.  

   

Wasn’t the self excitation feature added to allow the SD8 to come online without a battery on line?  

With a Z-13/8 architecture the battery is always connected to the SD8 circuit.  

Assuming proper maintenance of the battery, is there any significant/reasonable simplified component reduction possible or advisable in the self excitation feature for the SD-8 ? (ref. message 44709 below)  

   

Thanks,

    Yes, and the diodes added to the disconnect relay to allow it

    to energize from EITHER the SD-8 or the Battery . . .

    ???? No, normal ops call for the SD-8 to be in the

    OFF position.

    Your right. The self excitation feature is based

    on the notion that one might find themselves airborne

    with a dead battery. I recall the conversation now. I

    think we decided that the band-aid stacked on top of

    the original Z-13/8 design goals was unnecessary

    and presumes that an OBAM airplane builder would

    find themselves in that situation after takeoff.



    Given that you, I and 99.9% of the folks who read

    this list will have a well considered Plan-B and

    a preventative maintenance program to support it,

    the SD-8 self-excitation and dual-feed for the

    alternator relay are unnecessary and only adds to

    parts count.



    Thanks for the reminder! I think I'll take those

    out.



    Bob . . .
