Solution

1. Preparation

Gather tools: jumper cables, multimeter, socket set, and protective gloves.
Ensure both vehicles are in park or neutral with the parking brake engaged.
Disconnect any accessories that may draw power.

2. Jump Starting the Battery

Position the Vehicles: Park the assisting vehicle close to the F-150, ensuring both are turned off.
Connect Jumper Cables:
- Connect the red (+) clamp to the positive terminal of the dead battery.
- Connect the other red (+) clamp to the positive terminal of the working battery.
- Connect the black (-) clamp to the negative terminal of the working battery.
- Connect the other black (-) clamp to an unpainted metal surface on the F-150 (ground).
Start the Assisting Vehicle: Let it run for a few minutes to provide a charge.
Start the F-150: Attempt to start the engine; if successful, let it run for at least 20 minutes.

3. Battery Inspection and Replacement (if necessary)

Remove the Battery:
- Disconnect the negative (-) terminal first, followed by the positive (+) terminal.
- Unbolt the battery hold-down clamp using a socket wrench.
- Carefully lift the battery out of the tray.
Inspect Battery: Check for any physical damage or swelling.
Replace Battery (if needed):
- Install the new battery into the tray.
- Secure it with the hold-down clamp.
- Connect the positive (+) terminal first, followed by the negative (-) terminal.
