Install Battery and First Start Attempt

What happens here

The creator positions the charged 6-volt battery into the Jeep's battery tray, ensuring proper terminal orientation (positive to positive, negative to negative, though the vehicle has a positive ground system). He secures the battery terminals with a wrench. He then checks the engine oil level with the dipstick, noting it's black but full. He attempts to start the Jeep by turning the ignition key and pressing the floor-mounted mechanical starter switch. The engine turns over but does not fire, and the starter sounds weak.

Goal: Install the charged battery into the Willys Jeep and attempt to start the engine.
