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.

    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. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=481650#481650

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. Bob . . .
