Ask The Editors: Where Is My Fusible Link?

Not a fuse but a fusible link.
Most of us understand how a fuse works- too much voltage passes through a circuit and it blows to sever the connection before the spike can damage components further down the line.
The fusible link is similar but a bit different. They are simply strands of thin wire wrapped in a fireproof covering located between harnesses. They work like a fuse in that when a surge of voltage comes through, they actually melt before letting the components they connect to receive the damaging electrical load. Because they are wrapped in fireproof housing, the damage is isolated to the fine wires inside. The bad news of course is that when they’ve done their job for you, replacement is the only option.

Your 2005 Polaris Sportsman does indeed make use of a fusible link. It is OEM part # 2202147.
We’d like to tell you exactly where it can be found but you don’t mention in your question whether you have the 90, 400, 500, 700 or 800cc model. In general, though, it will be located in the run between the battery and taillight assembly.
