There was a lot of R11 books that were missing
one or more pages in Appendix Z . . . we didn't
do a search-and-fix effort on that error because
the latest iteration is always available on
the website. I just downloaded a copy of the
current version from:
http://www.aeroelectric.com/R12A/AppZ_12A4.pdf
It's a big file . . . it may take a few minutes
for it to pop up after you call for the download.

See my posting of a minute ago . . .
The latest changes to the 'Connection are
listed and linked in the What's New? feature on
website.

Unlike generators that had over current or
over load protection built into their regulators,
alternators are inherently self-limited to
the amount of output current. They are
incapable of destroying themselves due
to drains that exceed nameplate ratings.
This assumes of course that they are
adequately cooled. In other words, if
the alternator is installed and fitted with
conditions that allow continuous operation
at full rated output, then having them
operate in current limited mode (10-15%
above nameplate) does not represent a
hazardous condition.
Alternator b-lead conductors in airplanes
have traditionally been protected by either
a fat breaker on the panel or (in the case
of Z-figures) some form of robust fusing
on the firewall. This "fuse" is depicted
as an ANL style device usually located
right next to the starter contactor.

Bob and/or others with help..
A couple of months ago there was some discussion about wiring a Skytec starter
per Vans recommendations. I believe Bob recommended eliminating the jumper wire
between the Starter B+ and 'S' terminal and connecting the 'S' terminal to the
starter contactor "I" terminal. I am installing a Skytec 149-NL starter and
the instructions say to remove this jumper wire when wiring for 24 volts and
leave it in for 12 v operation. Does removing the jumper effect 12 volt operation?
Also, I would like to add a 'starter engaged' warning light per Bobs'
recommendation in the "connection" by wiring the "I" terminal of the starter
contactor thru a 5amp fuse to the warning light. Any problem with doing both
wiring alterations?
Thanks,
Tom Packard
