Did some residential electrical long ago, know just enough to get by in most situations - and when not to mess with things out of my depth. Knowing when to lay off liability is important, and there is plenty of it in the OP's situation. Hearing that the wiring in this house was "rednecked" got my attention. There is no way in actual hell anyone outside of a licensed electrician could run down all of the problems that may exist due to wiring being "rednecked". Please get a qualified boots on the ground electrician to look things over. Getting the power company involved will only delay the inevitable. Don't mess around with this, someone you love (maybe yourself?) may die or get seriously hurt out of this.
