Abstract
Abstract A radio frequency remote control starting system for internal combustion engines is disclosed. A radio receiver is located at the engine that is to be started remotely and preferably mounted on or near the engine. The output of this receiver is connected to a plurality of solenoids and relays which are utilized to start the engine in response to an output signal from the receiver. The relays and solenoids are connected in parallel with the conventional starting system of the engine. An ''''on-off'''' switch is provided in the battery circuit of the engine. When the switch is in the ''''on'''' position, the engine can be started either remotely or by the conventional starting system. However, when the switch is in the ''''off'''' position, the engine can be started only by the conventional starting system. The receiver produces a signal to start the engine in response to a signal received from a small portable transmitter that is located remote from the engine.
