Fuses protect the tractor’s electrical system from potential damage. A blown fuse indicates that there is an overload or a short somewhere in the electrical system. If a fuse blows, replace it with a new fuse of the same capacity.
All fuses in the Monarch Tractor are replaceable by hand, without additional tools.
Before replacing a blown fuse, it’s important to determine what caused the fuse to blow, and then to make necessary repairs.
IMPORTANT: To avoid serious damage to the tractor and to the tractor’s electrical system, determine the cause of a blown fuse before replacing it.
