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

1. Inspect Battery Terminals:

   • Clean any corrosion from battery terminals using a battery terminal cleaner.
   • Tighten the terminal connections securely.

2. Test Battery Voltage:

   • Connect the multimeter to the battery terminals.
   • If the voltage reads below 12.4 volts, proceed to replace the battery.

3. 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

1. Check Starter Motor Connections:

   • Locate the starter motor and inspect its electrical connections for corrosion or looseness.

2. 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.

3. 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.
