At startup, the battery will supply the needed field excitation, but as soon as the alternator is working, they take over the job. (They are integral to the idiot line scheme in cars, however, so may not exist in aircraft units.) Negative. Neither the Prestolite (Ford style) alternators used on Cessnas, nor the Chrysler alternators used in Pipers have the additonal "diode trio". Only the aftermarket STCed INTERAV conversion uses a Motorola alternator with the diode trio. MikeM Skylane '1MM |
