Example The following is a schematic for a simple horn circuit. Study the schematic and the circuit operation text. Develop a Fault List, decide what questions you would like to ask about the circuit, eliminate items from the list, and prioritize the remaining items to test. Horn Circuit Operation If the ignition switch is closed, power will be applied to the horn relay coil and coil contacts. If the momentary contact horn switch is pressed, a magnetic field will be produced in the relay coil and the relay contact will close. The closed horn relay contacts allow current to activate the horn. The current finds its way back to the battery negative post to complete the circuit. When a circuit is not working correctly, like the horn circuit above, there are many possible causes, many things to test and check. The following is a Fault List of probable causes for the complaint "Horn does not work". FAULT LIST A dead battery A blown fuse Example — WSU http://ocw.weber.edu/automotive-technology/ausv-1320-automotive-elec.
