Engine Bay Inspection and Battery Diagnosis

What happens here

Open the truck's hood to access the engine compartment. Visually inspect the engine, paying attention to the turbocharger, alternator, and any visible wiring. Note the engine size (7.3L Power Stroke) and any written maintenance notes. Critically, examine the existing batteries and their terminals for corrosion or damage. The previous batteries are identified as Rural King Group 65 with a 72-month warranty, suggesting a similar replacement will be needed.

Goal: Identify engine type and assess battery condition
