Charging Issue

Hello Everyone, I am having an issue with my car not charging. I replaced the alternator when i first purchased the car as long as the regulator which had a poor ground and fried. This was about 4 months ago and it's been fine since. However now it won't charge. I'm getting battery voltage at the alternator with key off. Key on i'm getting .10 on the field. Single post by the way. Also .10 at the regulator. I jumped the field wire on the alternator to negative post on battery and nothing. So i take it off and run to advanced and have them test it and it comes back good. So i swap the regulator and still nothing. Same thing test my posts and same results. Jump the alternator and nothing. I'm kind of stumped. Also just swapped alternator today under warranty and still same thing.
