1 Genera! information and precautions
A
Warning: fie/Ore carrying out any work on the electrical system, read through the precautions given in Safety first! at the beginning of this manual, and in Chapter 8. The electrical system is of 12-volt negative earth type. Power for the lights and all electrical accessories is supplied by a lead/acid type battery, which is charged by the alternator. This Chapter covers repair and service procedures for the various electrical components not associated with the engine. Information on the battery, alternator and starter motor can be found in Chapter 5. It should be noted that, prior to working on any component In the electrical system, the
battery negative terminal should first be disconnected, to prevent the possibility of electrical short-circuits and/or fires. Caution: Before proceeding, refer to Disconnecting the battery In the Reference Section of this manual for further information.
2 Electrical fault finding-general information
Note: Refer to the precautions given In Safety first! and in Section 1 of this Chapter before starting work. The following tests relate to testing ot the main electrical circuits, and should not be used to test delicate electronic circuits (such as antHock braking systems), particularly where an electronic con fro/ module is used.
General 1 A typical electrical circuit consists of an electrical component, any switches, relays, motors, fuses, fusible links or circuit breakers related to that component, and the wiring and connectors which link the component to both the battery and the chassis. To help to pinpoint a problem in an electrical circuit, wiring diagrams are Included at the end of this manual. 2 Before attempting to diagnose an electrical fault, first study the appropriate wiring diagram, to obtain a more complete understanding of the components included In the particular circuit concerned. The possible sources of a fault can be narrowed down by noting whether other components related to the circuit are operating properly. If several components or circuits fait at one time, the problem Is likely to be related to a shared fuse or earth connection.

5 Bulbs (interior lights) -renewal
General 1 Whenever a bulb is renewed, note Ihe following points: a) Ensure that the relevant electrical circuit is Isolated before removing a bulb. If
In
doubt, disconnect the battery negative terminal (refer to Disconnecting the battery In the Reference Section of this manual) before starting work. b) Remember that, if the light has just been in use, the bulb may be extremely hot. c) Always check the bulb contacts and holder, ensuring that there is clean metal-to-metal contact between the bulb and its live contacts) and earth, dean off any corrosion or dirt before fitting a new bulb. d) Wherever bayonet-type bulbs are fitted, ensure that the live contact(s) bear (irmly against the bulb contact. e) Always ensure that the new bulb is of the correct rating (see Specifications), and that it Is completely clean before fitting it.
