Replacing Fuse
1. The tractor electrical system is protected from potential damage
by fuses.
A blown fuse indicates that there is an overload or short
somewhere in the electrical system.
2. If any of the fuses should blow, replace with a new one of the
same capacity.
IMPORTANT
• Before replacing a blown fuse, determine why the fuse blew
and make any necessary repairs. Failure to follow this
procedure may result in serious damage to the tractor
electrical system. Refer to troubleshooting section of this
manual.
