CHAPTER NINE
ELECTRICAL SYSTEM
This chapter contains service and test procedures for electrical and ignition system components. Spark plug maintenance is covered in Chapter Three.

The electrical system includes the following systems:

1. Charging system.

2. Ignition system.

3. Starting system.

4. Lighting system.

5. Switches and other electrical components.

Refer to Tables 1-14 at the end of the chapter for specifications. Wiring diagrams are at the end of the manual.

ELECTRICAL COMPONENT REPLACEMENT

Most motorcycle dealerships and parts suppliers will not accept the return of any electrical part. If you cannot determine the exact cause of any electrical system malfunction, have a dealership retest that specific system to verify your test results. If you purchase a new electrical component(s), install it and then find that the system still does not work properly, you will probably be unable to return the unit for a refund.

Consider any test results carefully before replacing a component that tests only slightly out of specification, especially resistance. A number of variables can affect test results dramatically. These include: the testing meter internal circuitry, ambient temperature and conditions under which the machine has been operated. All instructions and specifications have been checked for accuracy; however, successful test results depend to a great degree upon individual accuracy.

Electrical Connectors

Many electrical troubles can be traced to damaged wiring or to contaminated or loose connectors.

The locations of the connectors vary by model. Also, if the motorcycle has been serviced previously, the connectors might be in different locations.

The electrical system uses three types of connectors. If individual wires or terminals of a particular connector require repair or replacement, refer to Electrical Connectors at the end of this chapter.
