Loading our BROKEN excavator BLIND and BACKWARDS

What happens here

With new batteries installed, the excavator's engine starts but exhibits severe computer malfunctions. The digital display shows a "CONT FAILURE" error, and the swing motor is locked, preventing the cab from rotating. This means the operator has no control over the machine's rotation, making precise positioning for loading extremely difficult and dangerous. The engine also won't shut off via the key, indicating further electrical/computer issues.

Goal: Identify the extent of the excavator's computer and swing motor issues.
