Correct about the ambiguity.
You can imagine that we in Europe - at least on the continent, where English
is not the native language - sometimes have difficulties with the correct
wordings :-)
Seasons greetings, and many happy landings !!!

Ah. I have seen the permanent magnet AC generator called both dynamo
and magneto. I try not to use the latter around aviation as it gets
confused with the magneto used for ignition.

I suppose that any device to produces electrical power from
mechanical motion could legitimately be called a generator. We call
multi-kilowatt devices powered by a diesel engine that produce mains
power a "generator set" here in the US.
Checking my dictionary:
dynamo: a machine for converting mechanical energy into electrical
energy; a generator.
magneto: a small electric generator containing a permanent magnet and
used to provide high-voltage pulses, esp. (formerly) in the ignition
systems of internal combustion engines.
alternator: a generator that produces an alternating current.
generator: a dynamo or similar machine for converting mechanical
energy into electricity.
So, now we have many words that seem to mean the same thing and are
suitable for confusing everyone.
And if you think about it, the 'alternator' we use produces DC output
by virtue of its diode array.
Isn't English wonderful! I know of no language that encourages such
ambiguity and outright confusion!

Thanks for the warnings, Mark. I did complete the circuit with a crowbar
and
a 2 amp breaker. I=92ve checked the whole thoroughly before installing.
But I
also left in all the Russian circuits so that I always can go back
easily
to the Russian system. In attachment you can see the small console with
the
circuit breakers (2 amp for overvoltage and 15 amp for the whole
circuitry).
The circular openings are for a Becker radio and a Garrecht Mode S
transponder. I=92ve chosen to build a separate console, so that I always
can
restore to the original system.
Seasons greetings, and many happy landings in 2008 !

Jan, make sure..... HOLY COW DARN SURE that you also use their
recommended
crowbar over-voltage protection with that particular device. The way
the
voltage regulator is designed, if the regulating pass transistor shorts
(and
it can... and does... and has) then unregulated voltage is fed right to
the
mains. The battery will try to keep it from going over the top, but
eventually you will boil the batteries too. Eventually the voltage will
be
high enough to start doing damage to your avionics. Seen this happen
three
times with those devices so far. Their kit offers a tiny little crowbar
circuit that pops a breaker and then opens a relay to disconnect the pmg
from the aircraft mains. Crude but effective. The only part you really
need from them is their crow bar circuit for $25. The rest is available
from any automotive hardware store and in fact that is the type of
relay
they provide in their kit.

I forgot to mention: I have a permanent magnet alternator, so that's why
I
have to use the PMR1 voltage regulator of B&C.

If you are interested in the B&C alternator system, see this page. It
is the wiring diagram for the B&C alternator. Very simple.

Jan,
To the best of knowledge in Europe we also call a generator with a
permanent
magnet a dynamo (like the one on your bicycle) and a generator whereby
the
latter has a controleable magnetic field winding.
Enough about this:
Have you heard anything from the FLA with respect to the Mode-S
codes=85?? We
and everybody else in Europe flying on the Russian register need those
before anybody can install a Mode-s transponder.
Do you have any idea what will happen if you have not one installed by
the
1st of January (and y=92re flying of course=85) and what the
restrictions are??
I certainly don=92t..

I supported the Parachute Shop as they advertise in Red Alert. Got a good price
from Don Mayer (the owner). 1-800-USA-CHUTE (1-800-872-2488). He is a Strong
