Solution

1. Preparation

Gather tools: Multimeter, socket set, wrench set, battery terminal cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Clean Battery Connections

Remove the positive (+) and negative (-) battery terminals.
Use a battery terminal cleaner to remove any corrosion from the terminals.
Ensure that the connections are tight and reattach the battery terminals, starting with the positive terminal.

3. Test and Replace Battery (if necessary)

Reconnect the negative battery terminal.
Test the battery voltage again; if it's below 12.4 volts or fails the load test, replace the battery.
If replacing, ensure the new battery matches the specifications for the F-150.

4. Check Starter Relay

Locate the starter relay in the fuse box under the hood.
Swap the starter relay with a similar relay to see if the clicking sound changes.
If the clicking persists, the relay may not be the issue.

5. Inspect Starter Motor

Locate the starter motor on the engine.
Check the connections to the starter; ensure they are tight and free of corrosion.
If accessible, use a multimeter to check for voltage at the starter when the ignition key is turned to the start position.
If the starter does not engage despite having voltage, replace the starter motor.
