Abstract

A method of enabling operation of an ignition system for outdoor power equipment may include monitoring status of a plurality of switches associated with respective components of the equipment where at least one of the respective components corresponds to one or more binary start fault operators, and setting a start enabling status for the one or more 5 binary start fault operators responsive to actuation of a start fault clearance operator.

First claim

That which is claimed:

1. Outdoor power equipment comprising:
an engine to selectively power the equipment;
an ignition system comprising a processor configured to enable selective powering of the engine based at least in part on a position of a first binary start fault operator and a second binary start fault operator;
a switch monitoring assembly configured to enable the processor to monitor status of a plurality of switches associated with a first component and a second component of the equipment, the first component corresponding to the first binary start fault operator and the second component corresponding to the second binary start fault operator; and
a start fault clearance operator configured to, responsive to only a single action actuation of the start fault clearance operator, automatically set a start enabling status for the first binary start fault operator and the second binary start fault operator.

2. The outdoor power equipment of claim 1 , wherein the first or the second binary start fault operator comprises a headlight module, a reverse module, a power take-off (PTO) module or a brake module.

3. The outdoor power equipment of claim 1 , wherein, responsive to a failed attempt to operate the ignition system to start the engine, the start fault clearance operator is selectable to set the first and the second binary start fault operator and at least a third binary start fault operator to the start enabling status.

4. The outdoor power equipment of claim 1 , wherein, prior to an attempt to operate the ignition system to start the engine, the start fault clearance operator is selectable to set the first and the second binary operator and at least a third binary start fault operator to the start enabling status.

5. The outdoor power equipment of claim 1 , wherein the ignition system is configured to provide an indication of each respective one of the first and the second binary start fault operator that is adjusted responsive to operation of the start fault clearance operator.

6. The outdoor power equipment of claim 1 , wherein the outdoor power equipment comprises a riding lawn care device or a walk-behind lawn care device.

7. The outdoor power equipment of claim 1 , wherein the outdoor power equipment comprises hand-held power equipment.

8. An ignition system for outdoor power equipment comprising an engine to selectively power the equipment, the ignition system comprising:
a processor configured to enable selective powering of the engine based at least in part on a position of a first binary start fault operator and a second binary start fault operator;
a switch monitoring assembly configured to enable the processor to monitor status of a plurality of switches associated with a first component and a second component of the equipment, the first component corresponding to the first binary start fault operator and the second component corresponding to the second binary start fault operator; and
a start fault clearance operator configured to, responsive to only a single action actuation of the start fault clearance operator, automatically set a start enabling status for the first binary start fault operator and the second binary start fault operator.

9. The ignition system of claim 8 , wherein the first or the second binary start fault operator comprises a headlight module, a reverse module, a power take-off (PTO) module or a brake module.

10. The ignition system of claim 8 , wherein, responsive to a failed attempt to operate the ignition system to start the engine, the start fault clearance operator is selectable to set the first and the second binary start fault operator and at least a third binary start fault operator to the start enabling status.

11. The ignition system of claim 8 , wherein, prior to an attempt to operate the ignition system to start the engine, the start fault clearance operator is selectable to set the first and the second binary start fault operator and at least a third binary start fault operator to the start enabling status.

12. The ignition system of claim 8 , wherein the ignition system is configured to provide an indication of each respective one of the first and the second binary start fault operator that is adjusted responsive to operation of the start fault clearance operator.

13. The ignition system of claim 8 , wherein the outdoor power equipment comprises a riding lawn care device, hand-held power equipment, or a walk-behind lawn care device.

14. A method of enabling operation of an ignition system for outdoor power equipment, the method comprising:
monitoring status of a plurality of switches associated with a first component and a second component of the equipment, the first component corresponding to a first binary start fault operator and the second component corresponding to a second binary start fault operator; and
responsive to only a single action actuation of a start fault clearance operator, automatically setting a start enabling status for the first binary start fault operator and the second binary start fault operator.

15. The method of claim 14 , further comprising providing an indication of each respective one of the first and the second binary fault operator that is adjusted responsive to operation of the start fault clearance operator.

16. The method of claim 14 , wherein, responsive to a failed attempt to operate the ignition system to start an engine of the equipment, the start fault clearance operator is selectable to set the first and the second binary fault operator and at least a third binary start fault operator to the start enabling status.

17. The method of claim 14 , wherein, prior to an attempt to operate the ignition system to start an engine of the equipment, the start fault clearance operator is selectable to set the first and the second binary fault operator and at least a third binary start fault operator to the start enabling status.
