Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect the battery terminals for corrosion; clean with a wire brush if necessary.
If the battery voltage is low, charge the battery using a battery charger or replace it if it cannot hold a charge.
Reconnect the battery terminals securely after cleaning or replacing.

3. Starter Motor Testing and Replacement

If the starter does not engage, remove the starter motor from the vehicle.
- Tools required: Socket set, ratchet, extension.
Test the starter using a multimeter to ensure it functions properly.
Replace the starter motor if it fails the test.
- Ensure that the new starter is properly aligned and bolted down according to manufacturer specifications.
