An electrical system, such as a motor control system for a motorized wheelchair, includes a two-part electrical connector which connects a first sub-system to a second sub-system. A reference terminal of one part of the connector is connected to a voltage detecting circuit but is otherwise unconnected: in the event of the connector terminals corroding, a conductive path develops between the reference terminal and one of the other, active terminals and the voltage detecting circuit detects the resulting change in voltage at the reference terminal.
