Sub-steps:
1. Reconnect the battery and verify the voltage with a multimeter.
2. If voltage is low (below 12.4 volts), charge or replace the battery.
Safety Warning: Always disconnect the negative terminal first when servicing the battery.

3. Clean Battery Terminals

Sub-steps:
1. Remove the battery cables from the terminals.
2. Clean the terminals and cable ends with a wire brush to remove corrosion.
3. Reconnect the cables, ensuring they are tight and secure.

4. Check Starter Motor

Sub-steps:
1. Locate the starter motor under the vehicle, typically near the transmission.
2. Inspect the electrical connections on the starter; tighten any loose bolts.
3. If necessary, remove the starter motor for testing or replacement.
  - Disconnect the electrical connections.
  - Remove the mounting bolts and take out the starter.
