ELECTRICAL 322  Circuit diagrams are arranged so that current flow is from top of the diagram ( Power source ) to the bottom of the diagram(ground ). The circuit diagrams are presented with Power distribution first, followed by individual circuits for each electrical system on the vehicle.  Power Distribution The Power Distribution diagram shows the connections from the battery to the Battery distribution unit & from battery distributions unit to Main distribution unit and cabin fuse & relay box.  Wire attributes Additional information is shown alongside wire 1. Wire colour: There are two kinds of coloured wire used in this vehicle. One is single coloured wire & other is dual coloured (striped) wire. The single coloured wire uses only one colour symbol (e.g. “W”). The dual coloured wire uses two colour symbols (e.g. W-L) the first symbol represents the base colour of the wire (i.e. “W”) & second symbol represents the colour of the strip (i.e. “L”). 2. Wire gauge - the cross- sectional area of the wire in square millimeters. This is included to help the technician to select the correct wire during harness repair.  Components Each component represented with his description & connector no. E.g. Description of component - Inlet metering valve & connector No.H-13
