Excellent and informative response Mike. This one is definitely a keeper
for my personal archive. Thanks for taking the time!

In summary, if all you own is the typical Sears 10A charger with
the time clock, then while the aircraft/motor home/boat is not
being used, hook the charger to the battery with the time clock
set to 6 hours. Go back and do it each month. That is the best
you can do to prevent the battery from loosing capacity while
inactive. During the six hours, the charger will put back the
self discharge, and then it will bubble the battery just enough
to stir the acid. This regemin is way better than just letting
the battery sit idle for six months.

--> AeroElectric-List message posted by: "James Redmon" <james@berkut13.com>
I am building a Berkut (a canard pusher) and have both a B&C primary
60-amp and backup 20-amp alternators. I am using the two alt, one battery
Z-12 design exactly as stated.
I recently ordered two alternator fuse (current limiter) assembles - 1
60-amp and one 40-amp from B&C (they don't sell a 20amp version). I just
read the update that mentioned that the minimum fuse for the 60amp
alternator should be 80-amp rated, and I also assume that this goes for
the 20-amp alt too.
So, my question is three fold - are the B&C fuses I have (60, 40) adequate
for the alternators I am installing? Do I need to exchange the 60-amp fuse
for an 80-amp version? Is the 40amp fuse too big for the smaller
alternator?
B&C mentioned that the fuses they sell can handle up to 80% rated current
for a short time, but the specifics are a little vague.
Thanks for your help! Love the book! More information on my web site if
you care to take a look.
