Code Numbering
When numbering connectors, grounds and splices, Jaguar Engineering uses a three-position format: CA001, CA002, etc. Because space is limited in this Electrical Guide the codes have, in most cases, been shortened. Thus CA001 001 becomes CA1 1, CA002 001 becomes CA2 1, etc.
Resistor Values
The omega symbol often used to represent resistance is not used in this publication.
- Whole-number resistor values below 1000 ohms are suffixed with "R", for example: 820R.
- Whole-number resistor values above 1000 ohms are suffixed with "K", for example: 820K.
- Fractional resistors values have "R" or "K" inserted at the position of the decimal point, for example: 8R2 represents 8.2 ohms, 1K0 represents 1K ohms.
Grounds
- There may be up to three eyelets on one ground stud.
- A, B and C are used to indicate the position of the eyelet on the stud: A first (bottom), B second (middle), C third (top).
- Two eyelet variations are used: a single eyelet and an eyelet pair. The single eyelet has a single leg, which is identified by an S; the eyelet pair has two legs, identified as L (left) or R (right).
EXAMPLE:
On figures where LHD and RHD circuits are combined and the ground designation differs from LHD to RHD, the RHD ground code is shown in parentheses. If the ground designation is the same for LHD and RHD, only one ground code is used, with no parentheses.
Relays
Serviceable Relays:
- are located in all three fuse boxes;
- do not have a separate relay connector (base);
- use the ISO pin numbering system (1, 2, 3, 4, 5);
- are identified by an R number unique only to the fuse box in which it is located.
EXAMPLE:
Non-Serviceable Relays:
- are located in all three fuse boxes.
- are a component part of the fuse box printed circuit board (PCB) and are arranged in singles or pairs.
- use the ISO pin numbering system 1, 2, 3, 4, 5 (single relay or top pair relay) and 6, 7, 8, 9, 10 (bottom pair relay).
- are identified by an R number unique only to the fuse box in which it is located.
Note: Pair relays are normally depicted separately.
EXAMPLE:
Fuses
Each fuse is identified by an "F" number unique only to the fuse box in which it is located.
EXAMPLE:
Networks
In most instances, networks are shown as a broken grey line to indicate that there is network communication between the depicted control modules. Refer to Figs. 20 for circuit details.
