Abstract
Abstract A method and apparatus for disabling a starter motor interrupts the ground conduit within the starter motor casing, breaking electrical continuity between the commutator and ground, by physically displacing a portion of the ground conduit. A cable, attached to a switch within the starter motor casing extends out of the starter motor and into the cab of the vehicle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
In a starter motor of the type having a commutator in electrical continuity with a ground connection accessible from the outside of the casing of the starter motor, an apparatus for disabling said starter motor comprising ground conduit means for establishing electrical continuity between said commutator and said ground connection, said ground conduit means including a first portion within said casing, said first portion including displacable means for selectively interrupting the electrical continuity between said commutator and said ground connection, and activation means, operatively associated with said displacable means and operable from outside of said casing for displacing said displacable means and interrupting the electrical continuity between said commutator and said ground connection.
Claim 2
Dependent Claim
113 words
