Electrical System

This chapter covers the following systems:

a. Charging.

b. Ignition.

c. Starting.

d. Lighting.

e. Directional signals.

Refer to Chapter Three for routine ignition system maintenance. Electrical system specifications are found in Table 1 (1966-early 1978) or Table 2 (late 1978-1984). Tables 1-6 are at the end of the chapter.


The charging system consists of the battery, generator and a voltage regulator.

Two styles of generators were used on 1966-1969 models. These were the standard (Figure 1) and fan-cooled (Figure 2) generators. The standard generator is a two-pole direct current two-brush unit. A voltage regulator controls the generator charging rate. When the battery charge is low or when current is used, the voltage regulator increases the generator charging rate. The charging rate decreases when the battery is near or at full charge and no current is being used.

The fan-cooled generator operates basically the same as the standard generator. The major differ ences are a larger housing and a higher current generating capacity. In addition, a fan is used to dissipate heat in the generator (7, Figure 2).


Whenever the charging system is suspected of trouble, make sure the battery is fully charged before going any further. Clean and test the battery as described in Chapter Three. If the battery is in good condition, test the charging system as follows.
