Solution

1. Preparation

Tools Required: Multimeter, socket set, wrench set, battery terminal cleaner, torque wrench.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminal connectors using a socket.
2. Clean any corrosion from the terminals and connectors with a battery terminal cleaner.
3. Reconnect the terminals securely.
4. If the battery voltage is low (<12.4 volts), charge the battery or replace it with a new one.

3. Starter Relay and Ignition Switch Check

Sub-steps:
1. Locate the starter relay in the fuse box.
2. Swap the starter relay with a similar relay to test functionality.
3. If the problem persists, check the ignition switch by using a multimeter to ensure power is reaching the starter relay when the key is turned.

4. Starter Motor Inspection

Sub-steps:
1. Remove the starter motor from its mounting using the socket set.
2. Inspect for any physical damage, including worn brushes or a burnt-out winding.
3. Test the starter motor directly by connecting it to a charged battery to confirm operation.
