Fusible link melted!

Hey y'all
The other day I went to start my car and saw smoke coming out of the hood so I immideatly unhooked my ground and found out that my fusible link by the bulkhead connector had melted. All I know it the wire comes off the starter relay, goes through the fusible link and bulkhead connector, goes to the ammeter, then goes back through the bulkhead connector and to the alternator. Should I buy a connector and replace it or have someone look at it? My brother says they are notorious for going bad (especially being 40 years old) haha
Thanks!

P.S it's a 73 Duster with a 318


now DO YOU SEE 67's post ? you need to BYPASS the ammeter and rewire it as shown above. TRUST ME IT WORKS
this is how i did mine , and i added a VOLT gauge
o riellys has the new fusible links for FIVE bucks
