Failing to charge

Ok. So I added a ground strap from the alt to the strut tower. There was a spark. Drove down the road, and the battery light came on. WTF? Drove about 30 minutes down the road, and the lights got dim, and then went dead [sm=bangbang.gif] Great. So I figured my battery charge was low, and I'd have it charged tomorrow. Went to work to get the battery from my work truck. Car fired right up, and on the way back lights got dim AGAIN! So, from here it seems my harness may have a short in it, since I bought a new alternator, and a good working battery. The bolt on the alternator is a ground strap right? Should not have sparked??? Any ideas?

Exactly. There was another ground about 5 inches away, but still seemed odd. Even so, is there was something that burned out in the alt, replacing it should have fixed it. Hooked the car up to an OBDII scanner and got torque converter codes, and I did not convert this car to 5 speed. Volt meter shows the battery at 10.00 with the car off, and 9.81 with the car running. It was around 9.78 and declined to 9.77 after two minutes of running at idle. Only thing left is to replace the harness.

Not sure if you're being sarcastic or not there ghost but your alternator on your neon does not have an internal regulator as is the case with most all dodge vehicles, they use the ECM/PCM to control the regulation. The alternator is simply a rotor, stator and rectifier with two field brushes. The two wire grey plug coming off the alternatorgoes right to the PCM which does nothing more than ground one of the field terminals to produce output.
