* In the fuse box itself: Many S-10s have fusible links incorporated *within* the main fuse block under the hood. Look carefully at the fuses; fusible links often look thicker than regular fuses and might have a slightly different color or marking.
* Near the battery: A common location for larger-gauge fusible links is near the positive (+) battery terminal. These protect high-current circuits like the starter. They might be attached directly to the battery cable or nearby on a bracket. They often look like short lengths of heavy-gauge wire with a weak point designed to melt.
* In the engine compartment wiring harness: Fusible links could be embedded within the main engine compartment wiring harness. This is less common, but possible. Locating them here requires a good understanding of the vehicle's wiring diagram.
To find them, you'll likely need to:
1. Consult a wiring diagram: A wiring diagram specific to your 1985 Chevy S-10's year, model, and options is crucial. A Haynes or Chilton repair manual is a good source for this. The diagram will show you the location and amperage rating of each fusible link.
2. Inspect the wiring: Carefully examine the wiring near the battery, the fuse box, and the main harness in the engine bay. Look for thicker wires that might have a slightly melted or discolored area—this is a strong indicator of a fusible link.
3. Trace the large-gauge wires: Follow the heavy-gauge wires from the battery and starter. These usually lead to fusible links.
4. Understand what you're looking for: Fusible links don't look like typical fuses. They are often short sections of thick wire with a weak point designed to melt if too much current flows through them. They might be color-coded or marked with an amperage rating.
Caution: Always disconnect the negative (-) battery terminal before working on the electrical system to prevent accidental shorts and injury. If you're unsure about any part of this process, it's best to consult a qualified mechanic.
