Motor Craft", N.F.P.A. No. 302, The Standards of the American Boat and Yacht Council, Inc., and the U.S.C.G. Safety Standards for Boat Electrical Systems (33 CFR 183).
CAUTION: (1) Make sure connections at terminals No. 1 and No. 2 are
the same polarity.
(2) Always STOP engines before switching to "OFF" position. Make-Before-Break feature allows switching between 1-all-2 positions with running engines.
Erratic operation, particularly after a very long periods of idleness, can be cleared by rapidly switching back and forth briskly several times without any load connected.
NOTE: If switch is to be mounted in an area subject to corrosion, it is recommended that a liquid electrical coating be applied to the terminal connections.
(1) Key Lock - Switch can be locked only in the "OFF" position. Key can be removed in either the locked or unlocked position.
(2) Alternator Field Disconnect - used to break the field current if the battery switch is inadvertently turned to the "OFF" position with the engine running. Hook-up instructions and applicability are explained in the diagram below.
The following diagram illustrates a typical installation.
