bmw325i_electrical_schematic_diagramThis Diagram applies for 1991 BMW 325i series. In these manual electrical components which works together are shown in the same schematic thus makes electrical troubleshooting easier. The power distribution schematics show the current feed through all the connection from the Battery and Alternator to each fuse and the ignition and light switches. If the power distribution schematics are combined with any other circuit schematic, a complete picture is made of how that circuit works.

In this manual all wiring between components are shown exactly as it exists in the vehicle; however, the wiring is not drawn to scale. To aid in understanding electrical operation, wiring inside complicated components have been simplified into “solid state”.

Overall this is divided into 8 sections which are Wire Size Conversion Chart; Symbols; Systematic Troubleshooting; Connectors Views; Power Distribution Box; Fuse Data; Components Location Chart; Components Location View; Splice Location Views.
