1 General information
**WARNING:
Refer to the Warning and Caution in Chapter 5, Section 1 under "Battery disconnection."
The electrical system is a 12-volt, negative ground type. Power for the lights and all electrical accessories is supplied by a lead/acid-type battery that is charged by the alternator.
This Chapter covers repair and service procedures for t11e vari› ous electrical components not associated with the engine. Informa› tion on the battery, alternator, distributor and starter motor can be

· Refer to illustrations 2.5a, 2.5b, 2.6, 2.9 and 2.15
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 that link the component to both the battery and the chassis. To help you pinpoint an electrical circuit problem, wiring diagrams are included at tt1e end of this Chapter.
Before tackling any troublesome electrical circuit, first study the appropriate wiring diagrams to get a complete understanding of what makes up that individual circuit. Trouble spots, for instance, can
found in Chapter 5.
It should be noted tha t whe n portions o f the e lectrica l s yste m are serviced, the negative cable should b e disconne cte d from the battery to prevent electrical shorts and/or fires.
