Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is in a safe location, with the ignition off and the parking brake engaged.

2. Battery Maintenance

Clean Battery Terminals:
- Use a wire brush to clean corroded battery terminals.
- Reconnect the terminals tightly, ensuring a solid connection.
Replace Battery (if necessary):
- If the voltage is below 12.4 volts or the load test fails, remove the old battery.
- Install a new battery, ensuring correct polarity (positive to positive, negative to negative).

3. Starter and Relay Inspection

Check Starter Relay:
- Remove the starter relay and inspect for any signs of damage.
- Swap with a working relay of the same type from another circuit.
Inspect Starter Motor:
- Disconnect the negative battery cable.
- Remove starter motor bolts and disconnect electrical connections.
- Inspect the starter for damage; replace if necessary. Reinstall and reconnect.

4. Ground Connection Check

Inspect Ground Connections:
- Locate the ground strap from the battery to the chassis and engine block.
- Clean and tighten connections to ensure a good ground.
