charging issues

[laborboy@xxxxxxxxxxxxx]

I have a 1964 Dodge Polara with 383, a/c, cd player, and high-voltage 
(Mopar Perf) coil. My alternator is standard, 50 amps. At driving speeds 
I get 14.5 volts charging with accessories on, no problems. My problem 
is at low idle in drive with accessories on (like at a stop light). My 
car cuts out with all accessories on in those situations; voltage is 
12.5 and clearly discharging the battery.

If I get a higher output alternator (60 amp, 75 amp), will that solve my 
problem at low idle? What amp should I go with? Is there a way to check 
the amperage while idling?

Is it possible that I have a short, or voltage/amperage drain?
