Battery not being charged, alternator tests OK

[MattwantsSpeed]

I hope someone can give me some ideas, I've posted this on another forum so maybe one of the 2 can help me. I know PKRWUD knows his ***** Well to make a long story short, my foot got stuck on the gas when I hit the brake and the car went into the curb/sidewalk sending my radiator, fan and fan shroud forward. About an hour before this I noticed the car wasn't starting, it sounded like the solenoid was clicking and then all of a suden that ***** happened. So we fixed the rad and right now the fan and fan shroud is off cuz I'm putting an elec fan on.

Now to the question/problem, My car was starting weird like I said and now the gauge has been real low and when I drive or rev, the gauge is real low and the AMP light is on. I took out the alternator and had 2 places bench test it and both came out good. I tested the battery and it came out marginal. SO I thought it was the battery. I tried the battery out of my g/f's mustang and it did the same *****! So now I'm stuck cuz it's not the battery or the alternator. When I hit that curb could I have jarred something or didn something?? I hate this electrical *****. Sorry I'm venting guys, thanx
