Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Gather tools including a multimeter, socket set, and a wrench set.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Check Battery Condition:
- Remove the positive terminal first, followed by the negative terminal.
- Inspect the battery for signs of swelling or leakage.
- Clean any corrosion found on the terminals using a wire brush and a solution of baking soda and water.
Replace Battery if Necessary:
- If the battery is weak (below 12.4 volts) or dead, replace it with a new one of the same type and rating.
- Reconnect the battery terminals, connecting the positive terminal first and then the negative.

3. Starter Motor Inspection and Replacement

Test Starter Motor:
- Locate the starter motor (usually near the engine block or transmission).
- Use a multimeter to check the voltage at the starter terminal while someone turns the key to the start position. Ensure voltage is present.
Replace Starter Motor if Faulty:
- If the starter does not engage, remove the mounting bolts and electrical connections from the starter.
- Install the new starter by reversing the removal steps, ensuring it is securely mounted.

4. Final Assembly

Reconnect the negative battery terminal.
Start the vehicle to check if the issue is resolved.
