A 20 Amp fuse is installed in your mower's wiring harness to protect
the mower's electrical system from damage caused by excessive
amperage.
If the electrical system does not function, or your mower's engine will
not crank, first check to be certain that the fuse has not blown. It is
located near the battery.
Always use a replacement fuse with the same amperage capacity as
the blown fuse.
