If you cannot use one of the same amper-
age, use one that is lower, but as close
to the rating as possible. If the amperage
is lower than that specified, the fuse
might blow out again but this does not
indicate anything wrong. Be sure to get

return the substitute to its original clip.
It is a good idea to purchase a set of
