Fixed (as per the cited reference) by placing a diode in the sense wire. Th
e regulator voltage is thereby increased by the voltage drop across the dio
de; select an ordinary diode or Schottky depending how much voltage increas
e is needed.

I follow many discus on the Rotax regulator, in the past I use 3x912
engines and I have troubles with Ducati Reg. I install Ektik regulator and
4 years ago he is broken.
After many investigations on the web I discover on the "Aero Hesbayes web
site" the regulator as follow:
P/N Shindengen Mosfet FH020AA regulators (official distributor)
I looked for a rectifier with draconian criteria and without any compromise
:
- Good regulation (super stable voltage)
- Cheap
- Reliable
- Which does not heat up too much (no waste of energy)
- Easy to mount
- Light
I have install this reg since now 4 years with total satisfaction.

Hi Group We know that poor connections cause high resistance. Push a lot of current
through a high resistance joint and it makes heat. As far as Rotax Faston
connectors, many of the old engines have really crappy Fastons for the job at
hand. Probably just plated copper. There are better Fastons made out of Phosphor
Bronze. I urged B+C to make it known in the install manual, don't know if
they did or not. Anyway I think they sell them as an install kit and hope they
are including with the Regulator. At least the high current 2 yellow wires should
have them installed. I bent mine to give a little extra tension and dabbed
on a little CRC 2-26 (ACF-50 works too). I forget the name of the I think German
Regulato5r Mfg, but it would not honor warranty unless Phospher Bronze Fastons
were used. Here's B&C link to their offering:

Ron,
I would not use ACF-50 as a conductor for the following reason. I also fly
a Trike with a Rotax 582 & a couple of years ago I removed the starter moto
r to check the wear on the brushes. The starter housing (which is the negat
ive connection) is mounted externally on the side of the engine using 2 lar
ge Allen Key headed bolts. As I've been using ACF-50 (bought in 4 Litres) f
or approx 10 years I always use it on nuts & bolts especially when I'm refi
tting them. On this occasion I dipped my 2 starter mounting bolts in the AC
F-50 & duly screwed them in until hand tight & then fully tighten them with
the Allen Key tool. I did an engine test start & run & all was perfect. A
week or 2 later I had to fly to my Inspector's airfield for the aircraft's
Annual Inspection. I started my Trike, took off, flew the 1.5hr trip, lande
d & shut down the engine. After the Inspection process was completed, I tri
ed to start my engine for the homeward flight but the prop wouldn't even tr
y to turn & neither would it with the assistance of battery jump leads from
a running car engine! We eventually got the engine going by hand turning t
he prop. On the homeward journey I dropped into a friend's airfield for a c
hat & cup of tea. On departure I had the same starting problem again & as b
efore, hand proping worked!
On arrival home I removed the starter & found that all of the starter's mou
nting base was coated in ACF-50. I dried all of it off along with the matin
g engine area & the 2 mounting bolts. The engine started on the first turn
of the ignition key & hasn't failed to start in the 2 years since.
Lesson learned = don't put ACF-50 anywhere near an electrical connection!
