Abstract
A watercraft includes an anti-theft switch which disables the starter button and provides a kill signal to the engine, thereby preventing unauthorized use and inadvertent draining of the battery.
Claims14
A watercraft comprising a hull, a battery, an engine having a crankshaft, a starter motor configured to rotate the crankshaft, a starter switch moveable between at least first and second positions, a starter circuit configured to connect the battery with the starter motor when the starter switch is in the first position and to disconnect the battery from the starter motor when the starter switch is in the second position, an engine controller configured to control at least one of fuel supply and ignition for operation of the engine, a kill switch moveable between at least first and second positions, a kill circuit configured to prevent operation of the controller when the kill switch is in the first position and to allow operation of the controller when the kill switch is in the second position, a third switch moveable between at least first and second positions, and a third circuit configured to disable the starter circuit regardless of the position of the start switch and to actuate the kill circuit regardless of the position of the kill switch when the third switch is in the first position.
A watercraft comprising a hull, an engine having a crankshaft, a starter motor configured to rotate the crankshaft, a starter switch moveable between at least first and second positions, a starter circuit configured to operate the starter motor when the starter switch is in the first position and to prevent operation of the starter motor when the starter switch is in the second position, an engine controller configured to control at least one of fuel supply and ignition for operation of the engine, a kill switch moveable between at least first and second positions, a kill circuit configured to prevent operation of the controller when the kill switch is in the first position and to allow operation of the controller when the kill switch is in the second position, and third user-operable switch device comprising means for disabling the starter circuit and bypassing the kill circuit when the third switch device is in a first state.
A watercraft comprising a hull, an engine having a crankshaft, a starter motor configured to rotate the crankshaft, a starter relay powering the starter motor, a starter switch configured to activate the starter relay, an engine controller configured to control at least one of fuel supply and ignition for operation of the engine, a kill switch configured to kill the engine, a third switch device comprising kill switch bypass switch, the kill switch bypass switch being disposed remotely from the starter relay, and a rider's area supported by the hull, the third switch device including a user-operable switch disposed in the rider's area.
An electrical system for a vehicle having an engine, the electrical system comprising a power source, an engine controller configured to control at least one operational parameter of the engine, a user-operable start switch, a user-operable kill switch, and a third user-operable switch device configured to disable the start switch and bypass the kill switch when in a first state and enable both the start switch and kill switch when in a second state.
