Solution

1. Preparation

Gather tools and parts before starting the repair.
Tools required: multimeter, socket set, battery terminal cleaner, load tester.
Safety warning: Disconnect the negative battery terminal before working on electrical systems.

2. Battery Inspection and Replacement

Inspect Terminals:
- Clean battery terminals using a terminal cleaning tool or wire brush.
- Ensure all connections are tight and secure.
Test Battery:
- Use a load tester to check the battery's ability to hold a charge.
- If voltage is low or it fails the load test, proceed to replace the battery.
Replace Battery:
- Remove the negative terminal first, followed by the positive terminal.
- Unbolt the battery hold-down bracket and carefully lift out the old battery.
- Place the new battery in position, securing it with the hold-down bracket.
- Connect the positive terminal first, then the negative terminal, ensuring tight connections.

3. Starter Motor Inspection

Check Connections:
- Locate the starter motor (typically situated near the transmission).
- Inspect wiring and connectors for corrosion, damage, or looseness.
- Tighten or replace any faulty connections.
Test Starter Function:
- If the battery is healthy and connections are secure, test the starter using a remote starter switch or jumper cables.
- If the starter does not engage, consider replacing the starter motor.
