							HOW TO USE THE CIRCUIT DIAGRAMS

HOW  TO US E THE  CIRCUIT DIAGRAMSAll of the information in this folder is intended for use with the 
Electrical Reference Library booklet.
The circuit diagrams are presented with Power and Earth distribution 
first, followed by individual circuits for each electrical system on the 
car.
Power Distribution
The Power Distribution diagram shows the connections from the 
battery to the engine and passenger compartment fuseboxes. It also 
shows the internal circuitry of the fuseboxes.
The fuse box details are followed by independent functionally specific 
circuits and then a Splices and centre taps section outlining the way 
in which internal harness splices and centre taps distribute power in 
the harnesses. This information should be used during diagnosis of 
electrical faults to check for symptoms in associated circuits and 
narrow down the search area.
Earth Distribution
The ground distribution section comprises a number of Headers and 
Splices tables. These are used in a similar manner to those in Power 
Distribution; to narrow the search area by checking for fault symptoms 
in associated circuits.Splices and centre taps
Header and splice tables present the joint(s) and wiring up to the first 
component. Splices are identified by a number with an alphabetical 
prefix and the wire colour.
The splice information shown on individual system circuits is not 
complete. Always refer to the splices circuit for complete 
information on each splice.
Wire length (Power & Earth Distributtion only)
The length of the wire in millimetres. This can be used to locate 
internal harness splices; look for the shortest wire between the joint 
and connector. For example, it can be seen that C574-4 is 150mm 
from joint A82.
Connectors
Header joints are identified by their corresponding connector number 
with a numbered suffix to indicate the pin-out detail of the wire, i.e. 
C289-1 identifies connector 289, pin number 1. Wire insulation colour 
is identified in the normal way. Where wires have a predominant 
colour with a secondary colour stripe, the main colour is identified first, 
i.e. LGS - Light Green with a Slate stripe.Line Types
This means the wire connects to another circuit.
The cup and ball symbol indicates the male and female halves of 
connector.
A. Plug on lead (Flylead) wired directly to the component.
B. Connector plugs directly into component.

Components
The name or description of the component is shown. A dotted outline 
indicates that the component is not shown in its entirety.Earth points
Earth points are identified with an eyelet symbol and a connector 
number, except where components are grounded through their 
fixings, when only the eyelet is shown.Fuses and Diodes
Fusible links (A) and current rated fuses (B) are identified as shown.
The direction of the arrow in a Diode symbol (C) indicates the direction 
of current flow. The Zener diode (D) - prevents current flow until a 
precise voltage is reached.
