ABSTRACT:
A test circuit for testing electrical characteristics of heating elements and switches coupled to individual elements. The switches are manually operated and conventionally may be mounted on a cooking range panel. The switches are operable to place the elements in an energized state wherein they are coupled to an electrical power source and in a deenergized state wherein they are decoupled from such source. The leads from the switches are typically coupled to the leads from the heating elements through a multi-conductor coupling harness wherein one harness segment has a plurality of male connectors and the other harness segment has a plurality of female connectors engageable with the male connectors. A T-connector has a first set of connectors engageable with the male connectors and a second set of connectors engageable with the female connectors and a third set of connectors coupled with the leads of a test circuit. The test circuit has an interlocking switch for providing a switchable connection between one only of the heating elements to its corresponding switch through the test circuit and a visual indicator, such as a neon light, indicates which element and switch are connected through the test circuit. The test circuit has an ohmmeter and ammeter with switches to select one of the meters to test either the resistance of the element-switch circuit or the amperage through the element-switch circuit when in its energized state. Additional switches are provided selectively to couple the ammeter to the power source and certain of the heating elements to the ohmmeter.
