Frequently Asked Questions
What is the purpose of the Alternator Field Disconnect (AFD) feature on this battery switch?
The Alternator Field Disconnect (AFD) feature is crucial for gasoline-powered engines. It safely de-energizes the alternator's field winding when the switch is in the OFF or a disconnected position, preventing potential damage to the alternator and ensuring the engine's ignition system is not inadvertently affected.
Can this battery switch be used with multiple battery banks?
Yes, this 3-position battery switch is designed to manage multiple battery banks. The selector allows you to choose between '1', '2', or 'BOTH' battery banks, providing flexible power distribution for your vessel's electrical systems.
Is this battery switch ignition protected for use on gasoline-powered boats?
Yes, this Blue Sea Systems e-Series battery switch is ignition protected, meeting stringent ABYC requirements, making it safe for installation on gasoline-powered boats where the risk of igniting fuel vapors exists.
What size ring terminals can be used with the studs on this battery switch?
The battery switch is equipped with 3/8"-16 tin-plated copper studs, each with a 7/8" length. This specification accommodates standard marine ring terminals with the appropriate stud size.
Does this battery switch allow for switching between battery banks without interrupting power?
Yes, the make-before-break contact design ensures that when switching between battery banks, a connection is maintained through the transition period. This prevents any interruption to your vessel's electrical systems, safeguarding sensitive electronics.
