Getting ready to do the wiring this week with the above items and diagram.  Slight
fly in my ointment here, hence I'm looking for some guidance.  I need to pick
up power for the MANL30.  Drawing has power source coming from Battery Contactor.
I do not have such!!  I am using the EFII Bus Manager which runs the
Alt and batteries through two switched relays for powering my busses. The primary
bus relay is rated up to 40A and the endurance bus relay for 30A.   Thinking
I need to tap into the power off the primary bus.  Any agreement or disagreement
regarding this? Attached is a pic of the power distribution from the Bus
Manager.
  Thanks for any insight  Dave

In case of smoke in the cockpit or imminent forced landing, the pilot should be
able to shut off all power as close to the source (batteries) as possible.

   Dug up this drawing on the FFII bus manager

Emacs!


    I'm mystified as to the rational for this architecture.
    It has always hot b-leads to both alternators. With
    this configuration, you could drive the MANL pump
    limiter to the main bus . . . but I'm not sure the
    relay inside the EFII is well suited to the
    task. Alternatively, you could tie it to BATTERY(+)
    and leave it hot all the time too.
