ABSTRACT:
An improved engine shut-off system is provided in which the likelihood of a safe failure is maximized and the likehood of an unsafe failure is minimized. Both terminals of the engine's first safety stop switch are connected in the ignition circuit so that if either wire leading to a stop switch terminal is grounded or breaks, a fail-safe condition exists. A first terminal of the first stop switch is connected in circuit to the main coil's primary winding, and the second terminal is connected in circuit to either the control switch means or the trigger coil. An optional second stop switch may be used in conjection with the first stop switch. The optional second stop switch may be a seat switch.
