These engines have three (3) blade type
automotive fuses. Engines equipped with a
high output charging system, will have one (1)
60-amp large blade type automotive fuse, in
addition to the three (3) blade type automotive
fuses. However, the 30-amp fuse is then non-
functional, as the 30-amp charging system
