I have a question for anyone currently using a voltage regulator other tha
n the standard Ducati brand.=C2- What has been your experience with the r
eplacement unit and would you recommendmaking the change.=C2- The posting
of electrical wiring diagram information would save time in making the ret
rofit.Thanks - Dave Weaver N912GR=C2-

The Rotax rectifier (voltage regulator) is not all that good and a
number of failures have been reported. A cheaper (about half the
price), better working alternative is available from a number of
suppliers.
I used the voltage-regulator Deere-AM101406. It has 5 terminals (the
Rotax rectifier has 6):
B+ (battery)
AC, AC (both to generator)
L, (not used, can be connected to an indicator light)
IGW (ignition / master switch, 12V from system)
The body is grounded, add a wire if necessary, good ground is important
The terminals are the same style for both rectifiers, so the wiring is
interchangeable and it plugs right in. The mounting bolt pattern is
different though and if you are using it to replace an existing Rotax
rectifier, you need an adapter or drill a new hole. The voltage with
the AM101406 is on the average 1V higher (14V) than with the Rotax
rectifier (13V), which is better for charging the battery. The voltage
fluctuates +-0.5V, which is normal. This rectifier is available from
several online sources although they may have different part numbers
for it and call it an equivalent replacement.
I have flown with it for several years now with no problems.
