The original alternator was possibly a 35 amp unit. The older cars ran all the charge current through the ammeter in the dash, a potentially hazardous design. I'm guessing that your higher amp alternator is pegging the old meter, because the old meter is designed for 35 amps max.
ammeter fluttering
I have a 1970 challenger rt/se.I have put in all new wiring from M&H,new 65amp altenator,new voltage rg,new ammeter.For some reason when I turn on lights or turn signal the ammeter goes crazy,it flutters big time even at hight idle.All grounds seem to be good,so what next anyone have any ideas.
Thanks

Nope. He's still pulling the same current as before, just has more charging capacity. The gauge should respond the same. Could be a poor ground connection.
