2. Battery Inspection and Replacement

Inspect the Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from terminals and cable ends using a wire brush.
Test the Battery:
- Use a multimeter to confirm voltage; if below 12.4 volts, recharge or replace the battery.
Replace the Battery (if necessary):
- Remove the old battery from the battery tray.
- Install the new battery, ensuring correct polarity (positive first, then negative).
- Tighten the terminals securely.

3. Starter Motor Inspection and Replacement

Testing the Starter:
- Locate the starter motor and disconnect its electrical connector.
- Apply direct battery voltage to the starter terminals to check if it engages.
Replace the Starter (if necessary):
- Remove the bolts securing the starter to the engine.
- Disconnect the wiring harness from the starter.
