Keep burning up alternators
 

Whats up everyone new to the forum but i have a issue involving my 1991 impulse. When i first purchased the car the alternator pigtail was in bad condition so i just spliced some connectors on the end. Now im replacing my alternator for the fourth time and i want to just make sure that that's not the reason for my alternators burning up. but i forgot which wire goes where there's an white and green wire and there's and black one. I checked for shorts on all wires no problems were found. Please help !
