Solution

1. Preparation

Gather tools: Multimeter, socket set, jumper cables, and a wrench.
Ensure the vehicle is in park or neutral, and the emergency brake is engaged for safety.

2. Battery Inspection and Replacement

2.1 Remove the negative terminal from the battery using a wrench to prevent short circuits.
2.2 Clean the battery terminals with a wire brush if corrosion is present.
2.3 Reconnect the terminals securely and check the battery voltage again.
2.4 If the battery is weak or old (over 3-5 years), replace it with a new battery of the same specifications.

3. Starter Motor Inspection and Replacement

3.1 If the battery is fine, locate the starter motor (typically near the transmission).
3.2 Disconnect the battery again to ensure safety.
3.3 Remove the electrical connections from the starter motor using a socket set.
3.4 Unbolt the starter motor from its mounting bracket and remove it from the vehicle.
3.5 Test the starter motor separately by connecting it directly to a charged battery; if it doesn’t turn, replace the starter motor with a new one.
3.6 Install the new starter motor in reverse order of removal and reconnect the battery.

4. Final Checks

4.1 Recheck all connections and secure bolts to the specified torque (typically around 15-25 ft-lbs for starter motor bolts).
4.2 Ensure all tools are removed from the engine bay before starting the vehicle.
