Abstract:
1. A system for pre-diagnosing nonoperating conditions in power chair lift and recline mechanism electrical circuits having a plurality of operating components, said operating components being at least one motor connected to said lift or recline mechanism, a transformer electrically connected between said motor and a wall plug, and a hand control device electrically connected to said at least one motor, said operating components interconnected by power cords, and at least two indicator lights connected in series with and on either side of said operating components at preselected points in the circuit for detecting electrical current passing through said preselected points, with a first indicator light positioned between the transformer and motor, and a second indicator light positioned between the motor and hand controller, whereby the status of said indicator lights is analyzed and interpreted together to identify by process of elimination possible causes for said inoperable condition.
