What is your question?
Car runs fine till you reach 2000 +rpms then the voltage gauge starts to fluctuate on the high side of gauge. Almost to the red danger bar. Check gauges light go on and off till car is shut off and restarted. Dash lights headlights indicator lights flickering the whole time while car is running till shut off and allowed time to reset Car also runs rough on acceleration and under load. I have replaced battery alternator and made sure all grounds are secure.
What makes this problem better or worse?
When it hits 2000 rpm

Be certain there is sufficient GROUND > chassis to vehicle body then to engine - bypassing all insulating rubber mounts.. Flashings lights and erratic instrumentation is indicative of a poor GROUND circuit - which can have adverse effects on engine performance as well.. Happy hunting!
Start grounding at various points and components using a jumper wire to see if that helps. Of course be careful not to short circuit any of the *positive circuitry* in the process. Good luck!
