BASIC ELECTRICAL SYSTEM OPERATION
A permanent magnet alternator is located on the left end of the crankshaft, and is the source of power for the ignition system and for recharging the battery.
When testing the electrical system, first identify whether the problem is related to the ignition system or the charging system.
Then refer to the appropriate section in this chapter to methodically test the components of that system.
Engine power is transferred to the driven sprocket by an endless, O-ring chain. This type of chain is internally lubricated and sealed by O-rings (Figure 53).
The chain requires regular cleaning, lubrication and adjustment for long life, as described in Chapter Three. Measurement of the chain, to determine its wear, is also performed in Chapter Three.
If the chain needs to be replaced, remove the chain by one of the methods described in this section. Refer to Table 1 for chain specifications.
