To find the likely point of failure (if you suspect this is the problem), you'll need to:
1. Trace the heavy-gauge cable: Follow the large wire running from the battery's positive (+) terminal. It will go directly to the starter, possibly with a few connectors along the way.
2. Inspect for melting or burn marks: Look closely at the wire itself, especially near the battery terminal and at the starter connection. A blown fuseable link will show signs of melting, discoloration, or even a visible break in the wire.
3. Check the starter solenoid: This component is often the source of problems even if the fusible link is functional. If the solenoid is clicking but not engaging, that might be the culprit.
Important Note: Working on a vehicle's electrical system can be dangerous. Disconnect the negative (-) battery terminal before starting any work. If you're not comfortable performing this type of repair, it's best to take your S-10 to a qualified mechanic.
