Title: Electrical interconnection circuitry from a rotating body to a relatively stationary body

Abstract: In an electrical system requiring an electrical interconnection between a rotating body and a relatively stationary body, a circuit provides a highly reliable electrical interconnection between the bodies through the use of multiple rotary electrical connection assemblies connected in parallel across the rotating interface during normal operation, and connected in series, from the relatively stationary body through one of the rotary electrical connection assemblies to the rotating body and returning to the stationary body through another one of the rotary electrical connection assemblies, for verification of the electrical continuity of the interconnection during a testing operation.
