I installed a volt meter in my truck and when I started it up it idled at 12v and if I rev the engine as high as it will go the volts will jump up to 14 for a long time and then it comes back down to 12 and then it dropped down to like 11 and some times regardless of if it is at 12 14 or 11 the needle will start jumping back and forth. I have a brand new alternator freshly tested battery and a voltage regulator that is less than a year old. Anyone every hear or seen this?

thanks guys
