Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is in park (or neutral for manual transmissions) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Examine the battery for any signs of swelling or leakage.
- Clean battery terminals using a wire brush and a mixture of baking soda and water if corrosion is present.
Replace Battery (if necessary):
- Remove the positive terminal first, then the negative terminal.
- Unscrew any clamps holding the battery in place and carefully lift it out.
- Install the new battery, securing it with clamps, and connect the positive terminal first, followed by the negative terminal.
- Ensure terminals are tight and clean.

3. Starter Motor Inspection and Replacement

Inspect Starter Motor:
- Locate the starter motor (usually found near the transmission).
- Check for loose wiring or connections at the starter.
Replace Starter Motor (if necessary):
- Disconnect the negative battery terminal again for safety.
- Remove the electrical connections from the starter (note their positions).
- Unscrew the bolts securing the starter to the engine block.
- Carefully remove the starter motor and replace it with a new one, ensuring it is secured with the proper torque specifications.
- Reconnect the electrical connections and the negative battery terminal.
