Alternator or Wiring problems?

Posted a question regarding this yesterday. I'm pretty sure I have a wiring problem in my 2000 Jeep Grand Cherokee. Runs & drives fine, but just a few minutes after starting the Jeep, the gages all shut off & all the dash lights light up like you've turned the key but not started the engine yet. Now interior lights are acting crazy also. Any ideas where to start looking for the problem?

Update:

Dad used the voltage meter to check the battery yesterday when it acted up again & the readings did not change at all - that's what has led us to believe it is truly a wiring issue. Would the reading change if there were a problem with the voltage regulator? Also - had problems with the power locks & windows they quit working almost a year ago - could that be related as well?

    Sandypaw, it could be either, how you describe it, looks more like moisture got into the circuitry, where two sections of the loom join, or other items join the loom.
