how to fix my Honda CR-V that won't start and just clicks

Solution

1. Preparation

• Tools Required: Socket set, multimeter, OBD-II scanner, battery terminal cleaner.
• Safety Warnings: Disconnect the battery before working on electrical components.

2. Battery Inspection and Replacement

1. Inspect the battery terminals for corrosion and clean them using a battery terminal cleaner.
2. Ensure the connections are tight and secure.
3. If the battery voltage is below 12.4 volts, charge the battery or replace it with a new one (12V, 500 CCA recommended for Honda CR-V).

3. Starter Relay Check

1. Locate the starter relay in the fuse box under the hood.
2. Remove the relay and visually inspect it for signs of damage.
3. Swap the starter relay with a similar relay to see if the problem resolves.

4. Starter Motor Inspection

1. If the clicking persists, access the starter motor located on the engine block.
2. Disconnect the electrical connectors from the starter.
3. Use a multimeter to test for voltage at the starter terminal while a helper turns the ignition key.
   • If voltage is present but the starter does not engage, it may need replacement.
   • If no voltage is present, trace the wiring back to the ignition switch.

5. Ignition Switch Testing

1. Access the ignition switch, usually located on the steering column.
2. Use a multimeter to check for continuity across the ignition switch terminals while the key is turned to the start position.
3. Replace the ignition switch if it fails the continuity test.
