Where are the fusible links on a GM Truck?
For what it’s worth, GM uses 5.0 mm sq. fusible links on their factory auxiliary battery option for the charging wire. Two, actually. One between the battery and the relay, and the other between the relay and the starter. In additon, GM has a 40 amp Mega fuse protecting the loads from the Auxiliary battery.
How big is the fuse for the fusible link?
Two, actually. One between the battery and the relay, and the other between the relay and the starter. In additon, GM has a 40 amp Mega fuse protecting the loads from the Auxiliary battery. Fusible links function differently than many fuses.
How long does it take to replace a fusible link?
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. A starter motor or ECU? Not so much. But fusible links look much different than fuses and are used for different applications.
What happens when a fusible link is blown?
When a fusible link does its job, it will break the circuit continuity, which is akin to cutting the wire. That results in cutting off power to the component. We see this a lot in starting systems. A fusible link will blow, and folks will incorrectly diagnose a failed starter motor—turn the ignition key…and nothing will happen.

In additon, GM has a 40 amp Mega fuse protecting the loads from the Auxiliary battery. Fusible links function differently than many fuses. It should be of interest to you why the factory choses fusible links for the main high current starting and charging circuits, versus fuses and circuit breakers elsewhere. Fuses of all types…
Why does a fusible link need to be unwrappled?
A fusible link on the other hand, works for protecting from catastrophic damage from a dead short that isn’t consuming the current by turning a motor, but is instead just generating heat. Thus the link melts apart, end of current flow. That is why the fusible link needs to remain free in air, unwrapped and unbundled with any other harness.
Where is the fuse block on a GMC Sierra?
