Posted: Mon Feb 11, 2008 6:07 am Post subject: Rotax 914 regulator mounting location

I am trying to decide where to mount the regulator in my 914 

installation. I hear these regulators fail if you draw more than 14 amps 

or so, possibly due to heat? Mine will be used as a backup, switched 

off, unless the IRalternator I have mounted on the vacpump pad fails.



Has anyone mounted it in the air intake area near the air filter? I am 

thinking of bolting it to the passenger foot well front in the air 

intake plenum. Seems like it would get cool air,and maybe some heat sink 

advantage from contact with the aluminum CD6.



It would be easier to just put it on top of a foot well. Anyone have any 

advice?



Thanks, Kevin

Heat, yes.

Have a look at http://contrails.free.fr/elec_ducati_en.php

Cool air, yes. But remember that anything protruding into the airflow, 

albeit internal, will generate drag, unless the airflow has really 

slowed down.

You can put it in any location you see fit, provided cooling air is 

sufficient and wires are not overly long.
