I would check to see if any power at the crimp connectors (probably no). But if there is, with a bunch of work and time, pull fuses from the electrical panel until voltage drops. Two people would make it easier or crimp a couple long wires with a light so you can view it from the electrical panel. You can always re-crimp later. If you find the fuse that kills power to it, then look to see what the panel is labeled if by chance the writing on the panel (if even labeled) is written in a language from the planet Earth. Most likely it is just what hoefler said.
