Chapter 9 Electrical System 

4. Alternator 

, 4LHA Sen 

4. Alternator 

The alternator serves to keep the battery constantly charg-

ed. 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 con-
tains diodes that convert AC to DC, and an IC regulator 

that keep the generated voltage constant even when the 
engine speed changes. 

4-1 Features 

The alternator contains a regulator using an IC, and has the 
following features. 

(1) The IC regulator is self-contained, and has no moving 

parts (mechanical contact points). It therefore has 
superior features such as freedom from vibration, no 
fluctuation of voltage during use, and no need for read-

justment. 
Also, it is of the over-heating compensation type and 
can automatically adjust the voltage to the most 
suitable level depending on the operating temperature. 

(2) The regulator is integrated within the alternator to 

simplify external wiring. 

(3) It is an alternator designed for compactness, lightness 

of weight, and high output. 

(4) A newly developed U-shaped diode is used to provide 

increased reliability and easier checking and 
maintenance. 

(5) As the alternator is to be installed on board, the follow-

ing measures are taken to provide salt-proofing. 

1) The front and rear covers are salt-proofed. 

2) Salt-proof paint is applied to the diode. 
3) The terminal, where the inboard harness is connected 

to the alternator, is nickel plated.
