WARNING: During installation, incorrect stacking of the fuse
block hardware can create a highly resistive connection that
generates heat. DO NOT place anything (i.e., washers)
between the fuse and either battery cable lug as this can
cause the fuse to overheat and blow open, resulting in a partial
melting of the fuse holder and cover. Before stacking, refer to
Figure 2.
