A fault detection system for an agricultural machine is configured to display to an operator a virtual layout of fuses and/or relays for the machine in an arrangement corresponding to an actual/physical layout of the fuses and/or relays on the machine. The system can monitor for fault conditions of the fuses and/or relays, and display a location of a fuse or relay corresponding to a physical location of where the faulty fuse or relay can be found from among other fuses and/or relays. A faulty fuse and/or relay can be highlighted, such as by changing a color of the fuse and/or relay, for rapid identification. The system can also display a list providing descriptions for the fuses and/or relays to assist with fault resolution.
