Default Voltage Issues Please Help

Hello all,

I have a 96 A4 with 135k miles, 2.8V6. For the past month the voltage meter has stayed around 8 volts, then will jump up to 12, 14, etc., then go back to 8. I replaced the battery and alternator, still same problem. Last night when I was driving it I heard a soft electrical cracking noise coming from the fuse box area; then for the next 2 hours the voltage gauge stayed around 14 consistently. Next day it was back to normal. I checked all of the fuses and they are fine. Has anybody come across this before? It's driving me nuts, please help. Thanks in advance!

Default I'd say, check ALL of the connections under the dash, especially the ones where...

the wires are attached from the battery, through the ECU box..
