Abstract
A diagnostic system for use in the electronic control circuit for motor actuated lift and/or recline mechanisms for chair wherein a hand controller is used to operate said lift and/or recline mechanisms, and wherein a series of LED indicators are situated at strategic locations in the circuit. The LED indicators can be used to determine whether electricity is flowing to such points in the circuit, which in turn will enable possible problems that might cause the hand control device not to work properly to be quickly more easily pinpointed by immediately narrowing the potential sources or causes of the problem.
