Why does my fusible link keep blowing?
Circuit Overloading The easiest way to blow a fusible link is to pass more current through it than it can handle. Doing this will open the floodgates for electricity, and the fusible link will blow out like a drinking straw on the end of a fire hose.
How do I know if my fusible link is blown?
The fusible link is essentially an in line fuse on the positive terminal of the battery. To determine if the fusible link has been blown , one test lead of your ohmmeter should be on the positive terminal of the battery and the other test lead should be on the end of the fusible link going to the circuit it protects.
Can fusible links be reset?
Fuses, fusible links, and circuit breakers protect an electrical circuit from damage caused by overload or short circuit. Fuses and fusible links operate once and then have to be replaced; a circuit breaker can be reset (either manually or automatically) to resume normal operation.
What happens when fusible link goes out?
When it fails, it will break the continuity in the rest of the circuit, preventing damage to other components down the line. A fusible link typically costs a couple of bucks and can be replaced in 30 minutes.
What’s the purpose of a fusible link?
A fusible link is a short piece of insulated low-voltage cable within an automotive wiring harness that is designed to protect the harness in applications where a fuse is unsuitable.
What happens when the fusible link goes bad?
Why use a fusible link instead of a fuse?
Fusible links—also spelled fuseable and fusable—serve a similar purpose to a fuse. (You can read more about fuses here.) Just like a fuse, the link is designed to handle a lower current (amp) load than the rest of the system so, in the event of a short or overload, the link will be the first failure point.
