Solution

1. Preparation

Tools Required:
- Socket set
- Multimeter
- Jumper cables
- Torque wrench
Safety Warnings: Disconnect the negative battery cable before working on electrical components.

2. Battery Inspection

Inspect the battery terminals for corrosion.
- If corrosion is present, clean the terminals with a mixture of baking soda and water.
- Ensure connections are tight and secure.
Test the battery condition:
- If the voltage is below 12.4 volts, recharge or replace the battery.

3. Starter Motor Check

Remove the starter motor:
1. Disconnect the negative battery cable.
2. Remove any covers or shields obstructing access to the starter motor.
3. Disconnect the wiring harness attached to the starter.
4. Remove the mounting bolts using a socket set and take out the starter motor.
Test the starter:
1. Connect the starter directly to a charged battery using jumper cables.
2. If it does not engage, replace the starter motor.

4. Reassembly

Install the new or tested starter motor:
- Position the starter in place and secure it with the mounting bolts.
- Torque the bolts to manufacturer specifications (typically around 30-40 Nm).
Reconnect the wiring harness and any covers or shields removed previously.
Reconnect the negative battery cable.
