		  I am getting about 3/4 of a volt drop through the essential buss 

diode when the battery is at a full 12 volts. When I throw the 

essential bus feed switch the Voltmeter creeps back up to 12 volts. 

Is this fairly normal? Thanks. John


	


   Yes. Diodes do have a small drop associated with

   them . . . which is insignificant when the alternator

   is running (bus at 14+ volts) and even less significant

   when the alternator is not running because the alt-feed

   switch is closed and the main bus is shut down.
