Replacing Fuses

The electrical system is protected by fuses. They require
no maintenance. However, if a fuse blows, check the
component and circuit for a malfunction or short.
To replace a fuse, pull it out of the fuse box and insert a
new fuse of the same type and size that you removed (Fig.
50).
