Abstract
A three-terminal module contains a relay with normally closed switch contacts and a delay circuit for the coil which opens the switch. The module switch contacts are wired between the engine ignition switch and the ignition coil of the engine. Malfunction detectors energize the delay, which eventually energizes the switch-operating coil, thereby stopping the engine. Opening and reclosing of the ignition switch enables the engine to restart.
