did you check the alternator fuse

I would take the alternator off and go get it tested, to be POSITIVE it is ok. Then check the wiring, from the alternator all the way to the battery, then check the battery for good, solid connections. Then check for loose connections, burnt insulation, etc. at the alternator.. In addition, check to be sure the Alt. belt is tight.

I wouldn't suggest to take the alternator to be tested which when they test it there is no load to get tested correctly, I would suggest you to test it your self, Just get a multimeter and check the volts, check at the starter point, at the battery and you should see the same volts, you should see 13 or over volts, if you see 12.5 or less, then your alternator is bad, but if you see good volts at the alternator side and low voltage at the battery, they you have a problem with the wires or the alternator fuse.

Check that and report back the results.

got the alternator rebuilt and still didnt fix the problem , checked the 80A fuse and relay and got some off of a parts car and now its charging , so fixed that problem . now im still having a studdering issue , rough idle , have to put throttle almost to floor to get off idle then wont go past 6000 in neutral . When i go down the road it feels like it has no power , with the throttle to the floor i still cant get over 55
