The 912 charging system is known for charging to a relatively low
voltage. Our voltage usually reads about 12.6-12.7 volts before
starting. In the winter when we don't fly as much, we keep a trickle
charger plugged into the system. In the winter, after the trickle
charger has been on overnight or longer, but is then unplugged, the
voltage unusually reads about 13.2-13.3 volts. The 12.6-12.7 volts is
normal for all the 912 engines I've seen. I have no idea why Rotax
builds it that way.

Hi Les,
Just run the return/overflow line down and out away from the engine to the outside
of the cowling. Don't put it down in the airstream, but up just inside the
cowling so it can drip if need be to the outside and not on a hot engine or exhaust.

I have the 40 amp rotax optional alternator. (It counts even if it's
still in it's box on the shelf ,next to the plane right?) In any event the
instructions include the option of just putting the tow alternators in parallel.
The 18 amp alternator is regulated to 13.5 v. The 40 amp alternator is set
to 14.3.
According to the hand out, somewhere around a 30-32 amp load the output
drops to 13.6 and the smaller alternator kicks in.

Mine has run at 13.8 volts for 350 hours (according to the voltmeter built
in to a Garmin GPS).

I think you are talking two different things here! The short tube off the
side of the carb is what the carb senses the different altitudes to
automatically change the fuel mixture. This should not be changed. If you are
using the
Rotax carb/heat box then they attach to the carb/heat box otherwise leave
them alone. Along with the Rotax carb/heat box came the carb trays that mount
below the carb to catch any overflow out of the tube and the trays have a 1/4"
line that you can divert to just below your bottom cowl. Getting bak to the
fuel return line, There was a setup that Rotax had to return excess fuel back
to the tanks if you wanted to. I just had my fuel line out of the Rotax fuel
pump split tint a T and go to the two carb inlets, That's It!
Did I make it more confusing? I hope not!!

The problem was a wire that was not crimped properly.
Now the voltage is 13.8 Volts and the light is off
Thank You
