1972-74 Time Delay Relay

Relay is a transistorized timing device designed to delay circuit continuity for a minimum of 20 seconds, after transmission has been shifted into high gear. Delaying circuit completion delays vacuum advance. Any opening of transmission switch contacts (downshift) of more than one or two seconds, causes relay to recycle and deny vacuum advance for another 20 seconds. A transmission switch interruption of less than one second will disable relay and prevent vacuum advance until next upshift cycle.
