What would fix my apparent and current electrical problems? on 2005 Chrysler Town & Country

My van's dash lights and gauges seem to go "crazy" at random times. The dash lights flicker at random times and while that is going on the gauges all start moving quickly up and down, and intermittently the radio shuts off as well. Several months ago the headlights were shutting off when we were going down the highway so we replaced the battery. We have had it hooked up to machines and no codes come up. I have bought a new battery, checked the alternator, and we still don't know what is going on.
