Clean Battery Terminals
- Disconnect both battery terminals.
- Clean any corrosion from the terminals and cable ends using a wire brush.
- Reconnect the terminals securely.

3. Starter Motor Testing and Replacement

Test Starter Motor
- Locate the starter motor (usually near the bottom of the engine near the transmission).
- Disconnect the wiring harness from the starter.
- Use a multimeter to check for voltage at the starter terminal when the ignition is turned to the start position.
Replace Starter Motor if Necessary
