| Subject: | B&C alternator for M14 |
There really is no right or wrong Herb, per se... But I would consider
wiring the old Generator switch in to disconnect the Pmagnet alternator
from the rest of the aircraft.

Subject: Yak-List: B&C alternator for M14
Attached is the info on the lightweight 10A alternator from B&C. This
is the one on my Yak 55. The photos at the bottom show the unit as
mounted on the upper back of the case. There are just 2 wires that
leave the Alt going to the regulator, blue in the photo, just behind
the right mag The regulator is mounted in front of the firewall on the
right, below the oil tank and medial to the battery tray. There are 2
wires leaving the regulator red/blk that enter the wiring harness. I
have not unwrapped the whole set of wires as the problem I had related
to the 2A CB just before the bus. In my installation the Alt is not
switched on the panel. The old "gen" switch is wired into to the main
breaker panel and the CB for "gen" is pulled so the GenFailure light on
the panel is not lit. The voltage meter in the cockpit is wired in as i
can see if the Alt is not charging. I can also see a variable output
with the engine speed. i do not pretend to know all of the facts, but
reading the long discussions i am not sure mine is wired right since the
switch is inop.

There are a couple of different ways that you could make the light work
like it used to. One would be to put a diode in line with the main feed
AFTER the wire that leads to the old generator light. This would allow
the light to come on if the alternator or any part of the regulator
circuit, or the over-voltage protection failed. Of course the kit
already contains a NEW light that you put in that tells you when the
over-voltage relay has tripped, but I think I would like the idea of the
old generator light telling me that the new alternator system had failed
(in any way) better than that. It is all up to the installer, but if
you can think of what you want, and how you want it to operate, it can
likely be re-designed to do that.

I have exactly the same installed on my Yak 50. Works well but II've
connected the output of the regulator circuit (behind the crowbar) to
the main bus in my Yak50 (in the big black box mounted on the firewall
at the inside; "shitok pitanije" or something but in cyrillic). So the
"generator fault" indicator now serves as a "master on" switch. I've
another light for the alternator fault.
