Brad - Just a my $.02 worth, but it sounds like your ignition switch is installed upside down.
Below are snapshots from a 1952 Truck owners Manual describing the ignition switch location, position and functions. The description of switch operation sounds like yours is 180 degrees off. Your switch also shouldn't have a third position according to the owners manual, so maybe replaced at some point in the past???
