Got it. Your point seems well taken, that current from other strings could
back feed through a 15 amp series fuse. That current, combined with the
current from the parallel string behind the same fuse would add up to more
than 15 amps.
But I'm still confused about the following statement:
"Take the output of one string plus the string fuse and you get 9 amps
(fuse)"
Thanks,
Drake
