Disconnect the negative battery terminal to prevent electrical shocks.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion using a wire brush.
- Tighten loose connections.
Test Battery Voltage:
- If voltage is below 12.4 volts, charge the battery or replace it if it fails to hold a charge.

3. Starter Testing and Replacement

Bypass Starter:
- Connect a jumper wire to the starter solenoid to check if the starter engages.
Remove Starter:
- Disconnect wiring from the starter.
- Remove mounting bolts (typically 13mm or 15mm).
- Carefully extract the starter from its housing.
Install New Starter:
- Position the new starter in place and secure it with bolts.
- Reconnect the wiring to the starter and ensure a secure fit.

4. Check Ignition Switch and Wiring
