1986 bmw l7 - Bimmerfest

Hi I have an 86 L7 and have been having some issues. I changed the battery and that solved the issue for about a day. Then I had the alternator tested and it failed. Purchased a new alternator and I am having the same issue. I don't have a fuse diagram so I am not sure which fuse to check for if there is one? Car will not start without a jump and once its jumped it instantly dies once disconnected from the other vehicle. I am new to BMW and am not sure if this is a known issue and couldn't find anything via search.

Thanks for any help or input

The electrical diagrams are in the ETMs listed by year in the left hand column.

Other than that I can't be of much help.
