Subject: AeroElectric-List: Hall effect sensor

=0ABob et al.=0A=0AI have a VMS 1000 engine instumentation system that pres
ently uses a hall effect sensor on the main alternator "B" lead to measure 
current for the display.=0AI'm now installing an auxilliary alternator on t
he vacuum pad which ties into the same starter contactor to battery contact
or lead as the main alternator, a la Figure Z-12.=0A=0AQuestions:=0AIs it f
easible to route the  starter contactor to battery contactor lead through t
he VMS hall effect sensor to monitor either alternator's current?=0AWhat is
 the possible effect during engine start, (current going in the opposite di
rection ), on the sensor which is marked for a particular wire/current dire
ction?=0A=0AAny advice much appreciated.=0APatrick Elliott, Surrey, England
