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.
