Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure adequate space and safety measures are in place.

2. Battery Inspection and Replacement

Check Battery Condition
- Clean the battery terminals with a wire brush if corroded.
- Tighten the connections to ensure a solid contact.
Replace Battery (if necessary)
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the battery hold-down bracket.
- Carefully lift out the old battery and install the new battery.
- Reconnect the terminals, attaching the positive terminal first, then the negative.
- Torque the terminals to the manufacturer's specifications (typically 5-7 Nm).

3. Starter Motor Check

Starter Motor Removal
- Locate the starter motor; it is usually mounted on the transmission bell housing.
- Disconnect the electrical connections to the starter (battery cable and solenoid wire).
- Remove the mounting bolts using a socket set.
- Carefully extract the starter motor from its mounting position.
Test Starter Motor
- Connect the starter motor directly to a battery to check if it spins.
- If it does not spin, replace the starter motor.
Install New Starter Motor
- Position the new starter motor in place and secure it with the mounting bolts.
- Reconnect the electrical connections.

4. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and monitor for any unusual sounds or issues.
