is blown, the electric starter motor will not operate. Try to locate and correct the cause of
the overload. If the cause is not found, the fuse may blow again. Replace the fuse with a
fuse of the same rating.
1. Open the fuse holder and look at the silver colored band inside the fuse. If band is broken
