I have uploaded the alternator wiring diagrams so you can see how the system works.
Check out the diagrams (Below). Let us know what happens and please upload pictures or videos of the problem.

Thank you so much for your help. The alternator seems to be working fine. Grounds all seem to be okay, I changed out the generator fuse and it started working.
