Here is a link for the Silent-Hektik wiring diagram:
http://www.silent-hektik.de/E_R4112.pdf
I assume that the "Kondens" is a condenser, aka capacitor; and that the "anlasser"
is the starter.
1. Even though the diagram shows the regulator connected directly to the battery,
I would connect it to the load side of the battery contactor instead. The
electrons will not know the difference unless the master switch is shut off.
2. Even though the Rotax manual warns against disconnecting the sensing wire from
the bus while the engine is running, that precaution is highly debatable.

Thanks for the link Joe! I wish these companies would pay a little money to
a professional translator. Even Rotax, with all the money they must be
making, cannot break loose with enough cash to pay a professional
translator. So struggling through the language barrier, I find myself
wondering what in the world this means:
"A safety fuse between alternator-regulator and battery plus leads to a
total failure in the case of insulate contact."
Are they simply stating the obvious, that if the fuse blows you will lose
the generator current? Or are they cautioning against putting a fuse in the
battery plus lead because it could lead to total failure of the regulator?
No fuses or breakers are shown in their drawing.
With regards to Rotax's advice not to disconnect the sensing wire when the
engine is running, I "think" these instructions state the same thing:
"only connect or disconnect the cable from the ignitions system when the
ignition system is turned off."
Do you agree that is what the above sentence is saying?
They also say "operating without battery or without cooling causes
failure." Really? The Ducati regulator does not require a battery.
Then, specific to Rotax 912 installation they say "the max length of the
plus and minus cables is 50cm (20 inches) with *NO* (emphasis is theirs)
fuses, switches or shunts."
Another point of interest is that only the R wire goes to the capacitor.
Every Rotax diagram that I have seen has at least the R and B+ going to the
capacitor. Most also use the capacitor as a junction for R B+ and C.
Any help figuring out exactly how to incorporate this regulator will be
appreciated. FYI I have abandoned the idea of running the main pump
directly off the regulator. The road I am following now is a variation on
Bob's Z-13/8, Z-16, Rotax installation diagram, and all the good ideas I
have gotten from this list. Basically, the 40 amp alternator will be
primary and the 20 amp generator will be auxiliary, as in Z-13/8. I have it
drawn out in rough and I think it works, but this new regulator info has me
scratching my head, and before I post my drawing for review I need to
actually understand the installation requirements for the Silent-Hektik.

> The Ducati regulator does not require a battery.
Ken and all,
It's been a long time since I designed our project circuits, but I had
the impression thant this regulator actually does need a battery to operate.
Back in 2003 when we conducted multiple tests with the Ducati regulator,
we found that it needs some voltage to come to life, so we concluded
that it was safer not to operate our electrically dependent aircraft
without a correctly charged set of batteries.
At the time we kept this 'List updated with our findings.
Concerning the Silent Hektik, it seems it can be a direct swap with the
Rotax/Ducati altenator, and can be wired liked suggested on fig Z16.
FWIW

As an experiment, I connected a wire from the load side of the battery contactor
to terminal "C" of the Ducati regulator. I went flying. At cruise speed, I
turned off the master switch which disconnected the battery from the electrical
system. As expected, nothing changed. Everything electrical kept right on working.
Shutting off the master switch had no affect, except for an intermittent
high voltage alarm. When the alarm sounded on the D-180, I was reluctant to
increase the RPM, not wanting to destroy any avionics. Back on the ground,
I downloaded the Dynon D-180 data to my computer to analyze. The maximum voltage
of 14.7 occurred at about 5200 RPM. The voltage fluctuated between 13.25
and 14.7
So once enabled, the Ducati regulator will remain enabled by its own output voltage.
The Ducati does not need a battery to continue operating. However, a
connected battery will have a stabilizing affect on system voltage. Without
a battery, the system voltage varied plus or minus 3/4 of a volt or 1.5 volts
total.
Based on this experiment, the Rotax charging system needs a battery for stability.
