A fuse will not work, you must replace with a fusible link. A fusible link is a solid wire (but smaller awg) placed in a current carrying line where there should NEVER be a dead short.

Typically, a fuse burns out when a circuit attempts to transmit too much current, severing the connection before the electrical charge can have any ill effects. … If there’s a surge, the link actually melts, as its resistance to heat is lower than that of the circuits it’s protecting.

What fuse would cause my car not to start?
