If the feed wire from the main batt bus to the relay is protected by the 10a fuse, why is it marked " * " ?

   Because the 10A (or larger) fuse exceeds the legacy

   rule-of-thumb for protection size of long, always

   hot feeders. Hence the alternate feed source "mini-

   contactor" and a short feeder between that contactor

   and the battery bus.

Bob,

OK, got it.



But now that begs the question of why there is a fusible link between the Ebus and Alt Feed Switch in Z-13/8 and not one in Z-32 between the contactor and Ebus?

Also, would you comment on my attached schematic (disregard pg 2)? In particular your thoughts on using the GP contactor as a contactor for Alt # 2.



Is there a prohibition of having both alternators online simultaneously?



Thank you,

John

Bob,

I missed your response to "Corrected Electrical Schematic" so disregard that part of my last post on this subject.



Thanks,

J
