2 wire nsizes smaller than the wire you are protecting.
IF the fusible link has "fused" [opened up, melted apart] it will not keep the alternator from working, BUT it will prevent the battery from receiving the charge.
94 Buick Lesabre replaced battery and alternator and the alternator is not charging the battery. Battery light is on and off. Is this fusable link. If so where is it located
I can tell you that on a 2000 mercury cougar it is a fuse on the positive cable between the battery and the alternator
You failed to mention what year the S10 is but, most of them use a fusible link to protect the alternator circuit.
What ever circuit that fusible link protected would be dead if the fusible link is blown.
The circuit the fusible link protects would be dead (no power).
There is a wire from the alternator to the starter motor. On the starter motor end, there is a fusible link that sometimes melts. With the engine off, check the battery volts and check the volts on the big red alternator wire. If they are not the same voltage, the link is open. If the link is open, the battery will not charge
A fusible link
There is not a fusible link between the alternator and starter. There is a regulator on the alternator. The starter is directly connected to the battery, as is the alternator.
It's located on the end if the main power wire coming off the alternator. This wire connects to the starter. The fusible link is located on the starter end of the wire.
Some 1990s had a fusible link. I am not aware of any with a fuse. The fusible link is between the alternator and the battery, connected with heavy wire. Kind of easy to miss. http://www.marksatterfield.com
Near the battery or on the back of the alternator
