Fusible Link
A melted fusible link can be detected either by visual inspection or by feeling with a finger tip. If its condition is questionable, use circuit tester or test lamp.

-
Never wrap outside of fusible link with vinyl tape. Important: Never let fusible link touch any other wiring harness, vinyl or rubber parts.
