The solenoid includes a wire coil with a top secured adjacent to an end of the wire coil. The top has an edge in which a groove is formed to receive an end of a wire forming the wire coil such that the wire is prevented from contact with the housing. A lead wire having two ends is electrically connected at one end to the end of the wire. The electrical connection is secured to the top with silicone.
