Solution

1. Preparation

Tools Required: Multimeter, battery load tester, socket set, fuse puller.
Disconnect the negative battery terminal to ensure safety while performing further checks.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the positive battery terminal using a socket set.
2. Disconnect the negative terminal.
3. Remove the battery from the vehicle.
4. Test the battery with a load tester. If the battery fails the test, replace it with a new one. Use a battery that meets the OEM specifications (typically 12V, 50Ah for Honda Civic).
5. If the battery is good, clean the terminals with a wire brush and reconnect them securely.

3. Starter System Check

Sub-steps:
1. Reconnect the battery terminals.
2. Check the starter relay by swapping it with a similar relay in the fuse box. If the vehicle starts, replace the faulty relay.
3. If the relay is functional, locate the starter motor and check for proper connections.
4. Use the multimeter to check for voltage at the starter solenoid when the key is turned to the start position. If voltage is present and the starter does not engage, replace the starter motor.
