So the other night the car started acting up, and all of the idiot lights came on and they wouldn't come off even if i disconnected the battery and connected it again. and the voltage was reading around 10 but the car was still starting, and now today i park it at work and was thinking if it was gonna start again so i tried and nothing it wouldn't start,
so i jump it and it starts and voltage is regular until i disconnected from the other vehicle it goes down to 9-10volts and then it dies,

so i replaced the voltage regulator and put the alternator back in and the wires started to burn and a lot of smoke came from the engine bay, my ground wires that connect to the alternator was burned to crap so i replaced that and tried to jump it again and it would start smoking,

i finnally took the ground wire off the alternator and it didn't smoke but started up just fine, but it still does the samething when i disconnect from the other car it dies,

somebody please help thanks

I would start by making sure you have your wires connected as shown ...
