HELP! Weird 1985 Pontiac Fiero Electrical Problems!

I put this video up on youtube to see if anyone could give me any advice on what could be wrong with my car after a 10-foot fall when the engine died and the steering locked up at 30 MPH resulting in flying off a small cliff. Please read the youtube video description and watch the video closely for full details. Thank you!

That is very strange, I recommend get this check from some auto repair shop.
