RE: [Chrysler300] Voltage regulating

I have a stock alternator in my G, rebuilt to stock specs and verified as working properly by the rebuild shop. I currently run a modern solid state voltage regulator. Going up to Reno last week, my ammeter was bouncing wide swings left to right rapidly for no apparent reason. I have tried at least 3 mechanical and 3 solid state regulators to eliminate the problem, yet is still returns. Doesn't happen all the time, and the battery is getting charged, but the ridiculous gauge action drives me crazy. Does anyone know the actual cause if the problem? If it is a thin vs. thick stator, how does the stator thickness fix the problem? Is it possible to put a thicker stator in place of the thinner one? I'm very good with electrical issues but this is one I haven't been able fix in all these years of ownership. I think it may be a first year design problem but still don't quite know what causes it. Could it be that dampers in the later ammeters mask the issue? If it was only that, the headlights would still flicker, so what is really going on here?

I might add, IF you are seeking reliable performance and not fretting
nit-pickers, if you have the 'thin' stator alternator, the 'thick'
stator unit also stops or seriously deminishes the flickering dance the
amp meter is doing, even at idle.
