Hello
The Rotax-Installation Manual, engine electric, 17-1, says: "Attention: Do not interupt circuit between Terminal C and +B of rectifier-regulator during engine run, as otherwise charging will stop."
What does that mean? Can I switch of the rectifier/regulator i.e. charging process with interupt of C/+B (similar to switching of the alternator field switch)?

Martin,
Based on what I've heard from Europa builders before me, the regulater will
destruct if you disconnect the "C" lead from the "B+" and "R" leads. It
looks to me like drawing Z-16 would do that, although I am dangerously
ignorant when it comes to electronics. I am waiting to speak to the Lockwood
engineers before I proceed with my schematics. If I was you, I would not
proceed until I fully understood the whats and whys of this issue. That is
why I can sign off with.....
Confused enough to consider selling the kit

This is one of several reasons why I like to get a real
schematic of the device being discussed. This is especially
important when you have conflicting anecdotal data. One of
my favorite minor philosophers once offered:
"There are no contradictions. When you believe you've
encountered a contradiction, examine your premises.
You will discover that one of them is wrong."

I'll suggest it means exactly what it says. Unless C is
connected, the regulator shuts down.

Some time ago, one of the readers on the List supplied me
with the following schematic:
http://www.aeroelectric.com/Pictures/Regulators/regul_912.jpg
An examination of the circuit reveals that terminal "C"
is the voltage sense lead for the regulator. Further,
it supplies power necessary to power up the regulator's
control circuits. Removal of power from this lead will cause
the system to simply shut down.
Figure Z-16 utilized terminal C as a shutdown or control
pin for about ten years with no reported difficulties. More
recently (June of last year) we modified Z-16 to move the
the control relay to the AC side of the regulator rectifier
as shown in the latest revision to Appendiz Z at:
http://aeroelectric.com/articles/Rev11/AppZ_R11J.pdf
Relays are a lot happier controlling AC voltage than DC
voltage and it seems a better location as shown . . .
but either configuration functions as intended.
