• Temporarily tighten all of alternator bolt and nuts. And then

tighten them in numerical order shown in the figure.

• Be sure to tighten “B” terminal nut carefully.
• Install alternator and check tension of belt. Refer to

.

• For this model, the power generation voltage variable control system that controls the power gener-

ation voltage of the alternator has been adopted. Therefore, the power generation voltage variable
control system operation inspection should be performed after replacing the alternator, and then
make sure that the system operates normally. Refer to
