Fuse Replacement
The fuse is located on the left frame support bracket.
Fuses seldom fail without a reason. If the fuse blows,
the source problem must be corrected or the new fuse
will blow again.
• Check for loose connections in the fuse holder and
replace holder if necessary. A dead short may be in
the cranking or charging circuit where insulation
may have rubbed through and exposed bare wire.
