Solution

1. Preparation

Ensure the vehicle is in park (or neutral for manual) and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Terminal Cleaning

Tools Required: Wire brush, battery terminal cleaner
Remove the positive (+) and negative (-) terminals from the battery.
Use a wire brush to clean any corrosion from the battery terminals and cable ends.
Reattach the terminals, starting with the positive terminal first.

3. Battery Replacement (if necessary)

Tools Required: Wrench or socket set
If the battery voltage is below 12.4 volts or the battery is old, replace the battery.
Remove the old battery by disconnecting the negative terminal first, then the positive terminal.
Install the new battery by connecting the positive terminal first and then the negative terminal.

4. Starter Motor Inspection

Tools Required: Socket set, multimeter
Locate the starter motor (usually near the transmission).
Check the electrical connections to the starter motor for tightness and corrosion.
Test the starter motor by applying direct voltage using jumper cables; if it does not engage, replace the starter motor.

5. Ground Connections Check

Tools Required: Wrench set
Inspect ground wires between the battery, chassis, and engine.
Clean and tighten any loose ground connections to ensure proper electrical flow.
