Sorry to hear it. You should probably try picking up a cheap multimeter at some point, so you can at least do simple checks like voltage, amperage, and test fuses. Basic things like that are really simple to do.
Good luck!
I second this. Even if you don't know how to use one now, its very easy to learn the basics when you actually have it in your hand.
And if you have a Harbor Freight near you:
