Ruined HO Santa Fe 0-6-0 Mantua Steam Locomotive - Can We Make It Run?

This locomotive was donated to the channel many months ago, likely because it didn't work. It appeared that someone had already tried to fix this locomotive since there were many wires out of place and several other unusual things about it. I thought I'd have a go today at getting it going again for the first time in likely many years. Apparently Mantua Tyco made this locomotive around 1977 making it 45 years old.
