No Headlights, Radio or Dash Lights

[yeller]

Hello.

I've had an intermittent problem with my headlights cutting out, along with my stereo and dashboard lights. When this happens, my air bag light will flash a certain number of times (it's been different).

This time, the airbag light is flashing 3 times, pause, 3 times, pause, etc.
And the lights, dash and stereo are out, and are not coming back on at all.

I have seen the http://www.veryuseful.com/ info, but don't really know what to do with it, or know whether or not it's relevent.

I drive a '90 5.0.

ANY help would be GREATLY appreciated.

Thank you!

Ian
