Fuse Replacement
The fuse is located next to the spark plug under the rear
frame. 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.
Replace the wire or repair with electricians tape if
the wire strands have not been damaged. Also look
for a wire pinched between body panels, burned by
the exhaust pipe or muffler, or rubbed against a
moving part.
Stop the rider mower and engage the parking
brake. Remove ignition key.
Pivot the hood assembly up. Disconnect the spark
plug wire and ground it.
Pull the fuse out of the lead wire.
Replace with new automotive fuse.
Make sure to reconnect the spark plug wire before
pivoting the hood assembly back.
