normal setup for most reg's is to allow current to pass to earth when
voltage drops low, ie ignition
on engine not running, the bias in reg diode changes as voltage comes up
preventing the light from
coming on as it cant get to earth. not having used a duke reg I couldnt
comment on that

Subject: Europa-List: Generator Light
A simple question but my aircraft has not flown for 2 years. I
cannot remember if the generator/charging light comes on when power is
turned on or not. My 914 is wired as shown in the manual. There is power
on the C pin of the connecting plug and if I earth the L pin of the plug the
light comes on, but not when plugged into the rectifier/regulator. Does the
alternator have to be rotating ? or have I got the dreaded Ducati regulator
failure.
If so any ideas??? Who is the cheapest UK supplier?
regards,
Mike
