Subject: AeroElectric-List: Lancair 360 Alternator field wire


My alternator field wire connects to the LR3C and at the moment, this wire runs
in close proximity to sensor wires (EGT,CHT,FF, etc) and Im getting some erratic
indications on the MVP-50. With the alternator off, everything is quiet. So
Im wondering what should be the minimum distance between the alternator field
wire and the other sensor wires? Also, the LR3C is supposed to be linear and
quiet, but would there be any benefit to locating an electrolytic capacitor between
terminals 4 and 7?

Thanks,

Angier Ames

Angier,=0A=0A=0AThe hypothesis is that noise on the field wire is interferi
ng w/ instrumentation.  I agree w/ you that it seems a little odd consideri
ng, as you point out that "... the LR3C is supposed to be linear and quiet.
." and that the max current it handles is around an amp.=0A=0AIn an effort 
to isolate some variables, is it practical to disconnect the existing field
 wire and route a temporary one away from the sensors and perform your test
