This document is a classic. AN-31 has been around for decades and updated many times. It's a great teaching/learning tool!

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 s witch the Voltmeter creeps back up to 12 volts. Is this fairly normal?-Th anks. John ________________________________ Message 4 _____________________________________ Time: 03:02:16 PM PST US From: "Robert L.

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.
