Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than indicated, or use any
other object in place of a fuse.

Never replace a fuse with a wire, even as a temporary fix.

near the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
