The function of the fusible links is like your house main circuit breaker-it distribute power if its blown or loose connection at the link and battery positive post it will not pass power to the vehicle's electrical system.
To test use a test lite and probe both side of the link-you should have power on each end of the link-sounds more like a loose connection
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is questionable, use circuit tester or test lamp.
