A method for diagnosing a fault in an electrical component using a diagnostic system having a plurality of sensors. The method includes positioning the electrical component in a predetermined position adjacent the diagnostic system and at a predetermined orientation with respect to the diagnostic system. The method also includes causing a predetermined level of electrical current to flow to the electrical component, the stationary sensors sensing electrical discharge emitted by the electrical component at an area of the fault, and the tangible computerized controller receiving sensor data from the sensors. The method further includes the tangible computerized controller executing the computer-readable instructions to process the sensor data to generate test information including a location of the electrical component at which the fault is occurring in at least two dimensions.

A method of detecting a gap between a valve seat insert and a port in a cylinder head may include heating the valve seat insert and the cylinder head and generating a thermal image of the valve seat insert and the cylinder head at an interface between the valve seat insert and corresponding port in the cylinder head housing the valve seat insert. The thermal image may be evaluated to determine the magnitude of a gap between the valve seat insert and the cylinder head based on a temperature at the interface between the valve seat insert and the cylinder head.
