Locate the fuse removal tool within the fuse box. The fuse removal tool is a plastic set of tweezers held in place with a plastic clip. Pull the fuse removal tool off the plastic clip to remove it. Grasp the top of the “ALT-S” fuse with the fuse removal tool and pull directly up to remove it from the socket.
Should I put a fuse on my alternator?
Fuses are installed to protect wires from an overload, meaning that the draw (amps) from the load (appliance) exceeds the capacity of the wire (the size or gauge). Under this premise, the only way an alternator needs a fuse is if either the battery or the alternator itself experiences a dead short.
How do you change an alternator fuse?
You can find a selection of replacement fuses in the fuse box. Sometimes, they are located on the inside of the fuse box cover. Replace the alternator fuse by pushing the new one into place using your fingers. Replace the fuse box cover by clipping it into place or using a Phillips screwdriver to tighten the screw.

Why use a fusible link instead of a fuse?
But certain automotive components require momentary higher peak current levels depending, so a fixed-rating fuse may not be ideal. Fusible links are also cheaper and easier to install than a dedicated fuse block, which is why you see them in OE applications.

Can a bad ground cause an alternator not to charge?
Poor ground connections are an often-overlooked cause of low charging output and alternator failure. Check for voltage drops at the positive and negative battery cable connections, the alternator BAT+ power connection and the engine ground strap(s). Voltage drops on the negative side can cause overcharging.
Can a fuse cause battery light to come on?
The fuses may or may not cause problems with your vehicle’s battery charging system. There could, however, be a blown fuse between the battery and the alternator.
