Circuit Protection - Fusible Links

Circuit Protection - Fusible Links

Fusible link is wire designed to melt and break continuity when excessive current is applied. It is often located between or near the battery and starter or electrical center. Use a continuity tester or a DMM at each end of the wire containing the fusible link in order to determine if it is broken. If broken, it must be replaced with fusible link of the same gage size.


Repairing a Fusible Link

Important: Fusible links cut longer than 225 mm (approximately 9 in) will not provide sufficient overload protection.
