fuel and temp gauge, turn signal lights flicker when lights on

My fuel and temp gauge and turn signal lights work fine when the lights are not on. But when the lights are on and the car is moving, the fuel and temp gauge, turn signal lights flicker. With the lights on and the car at a stop everything is normal again. I replaced the voltage regulator a few months ago but this voltage problem started up about 2 weeks ago. I replaced the alternator today with a Bosch rebuilt one I had laying around but it didn't fix the flickering issue. Does anyone have an idea of what the problem might be?
