Solution

1. Preparation

• Tools Required: Multimeter, socket set, wrench set, jumper cables, safety glasses, gloves.
• Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Battery Inspection and Replacement

1. Inspect Battery Terminals

   • Clean any corrosion with a wire brush and a mixture of baking soda and water.
   • Ensure terminals are tightly connected.

2. Test Battery Voltage

   • Reconnect the battery and use a multimeter to check the voltage.
   • If the voltage is below 12.4 volts, charge the battery or replace it if it fails to hold a charge.

3. Starter Motor Inspection

1. Locate the Starter

   • The starter is typically located on the lower side of the engine near the transmission bell housing.

2. Inspect Wiring

   • Check the wiring harness connected to the starter for any signs of damage or loose connections.

3. Check Starter Functionality

   • If the battery is good, use a multimeter to check for power at the starter solenoid when attempting to start the vehicle.
   • If no voltage is detected, the ignition switch or wiring may need further inspection.

4. Remove and Replace Starter (if necessary)

   • Disconnect the positive terminal from the starter.
   • Remove the mounting bolts and carefully take out the starter motor.
   • Install the new starter by reversing the removal steps, ensuring all connections are secure.
