65 Barracuda daily driver

So it turns out the problem was not the carb. I rebuilt the carb and my problem persists. I should have tested that first, but the problem is spark and not fuel. When the car won't start it's because there is no power to the coil. I swapped the coil with another one I had and no change. The wiring on this car is pretty bad and I will get a new harness for the V8. The car already has electronic ignition and electronic voltage regulator. I fixed more of the wiring and I still have that problem. I also noticed, and maybe that's new, that there was a little smoke coming from the bulkhead connector where the alternator output goes in. Now I'm worried the car might catch on fire. In November my old alternator went out. The parts store only had one in stock that was 65 amps instead of the 60 amp alternator that I had before that. Could that be the source of my problems? Again, the car typically starts with no issues when cold, but stalls sometimes when driving and won't start again for a while. Heat seems to be an issues, because it typically happens when it's hot outside or after driving for a while. I also added a tach since then, but I doubt that should affect anything. There are quite a few accessories coming off the the starter relay. Could that be an issue? Anyways, I'm at a loss and quite frustrated. Any ideas?
