Solution

1. Preparation

Tools Required: Battery terminal cleaner, multimeter, socket set, wrench set.
Safety Warnings: Disconnect the battery before starting any electrical work.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion from battery terminals using a battery terminal cleaner.
- Tighten the terminal connections securely.
Test Battery Voltage:
- Connect the multimeter to the battery terminals.
- If the voltage reads below 12.4 volts, proceed to replace the battery.
Replace Battery:
- Remove the negative terminal first, followed by the positive terminal.
- Remove the battery hold-down bracket and lift out the old battery.
- Place the new battery in the tray, ensuring it is oriented correctly.
- Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection

Check Starter Motor Connections:
- Locate the starter motor and inspect its electrical connections for corrosion or looseness.
Test Starter Operation:
- Use a jumper wire to connect the battery directly to the starter motor's terminal (safety: ensure the vehicle is in neutral or park).
- If the starter engages, it may need replacement.
Replace Starter Motor (if necessary):
- Remove any components obstructing access to the starter motor.
- Disconnect electrical connectors and remove mounting bolts.
- Install the new starter motor and reconnect electrical connectors.
