A choke in electronics is used for blocking the higher frequency known as AC. When this occurs it allows the lower frequency known as DC to pass through the electrical conductor.

A fixed choke is a choke that can not be removed or changed.

A 454 Chevrolet engine which is experiencing a choke light while the choke is physically open, indicates the choke is not receiving power. This can be caused by a loose connection or a defective choke.

The choke lever should be down for the choke to be off. In the raised position is choke on.
