my Honda Accord 9th Generation (2013-2017) won't start and just clicks what should I do

Solution

1. Preparation

• Safety Warning: Disconnect the battery before working on electrical systems.
• Gather tools: Multimeter, socket set, wrench set, screwdriver set, jumper cables.

2. Battery Inspection and Replacement

1. Inspect Battery:
   • Remove the battery terminals (negative first, then positive).
   • Clean any corrosion from the terminals and connectors.
   • Reconnect the battery and recheck voltage with a multimeter.
2. Replace Battery (if necessary):
   • If the voltage is below 12.4 volts or the battery is old, replace it.
   • Install new battery by connecting the positive terminal first, followed by the negative.

3. Starter Motor Testing and Replacement

1. Testing the Starter:
   • Locate the starter motor (usually near the engine block).
   • Use jumper cables to apply direct power to the starter motor's terminal.
   • If the starter engages and the engine starts, the starter may need replacement.
2. Replace Starter (if necessary):
   • Disconnect the battery again.
   • Remove the bolts securing the starter to the engine.
   • Disconnect the wiring from the starter.
   • Install the new starter by reversing the removal steps and ensuring connections are secure.

4. Final System Check

• After any replacement, reconnect the battery.
• Ensure all connections are tight, and check any fuses that may have blown during the initial failure.
