12.4 Alternator 12V/60A (Optional)
The alternator serves to keep the battery constantly charged. It is installed on the cylinder block by a
bracket, and is driven from the V-pulley at the end of the crankshaft by a V belt.
The type of alternator used in this engine is ideal for high speed engines with a wide range of engine
speeds. It contains diodes that convert AC to DC, and an IC regulator that keeps the generated voltage
constant even when the engine speed changes.
