I tried to start my 1996 328is. It will not turn over. Their is no noise at all, no lights, seats, doorlocks, etc...I haven't driven the car in 3 weeks but it has been in a coverered garage.
Your battery was probably killed by heat, sitting and not being used and getting hot inside a garage will kill a battery, heat is a battery's worst enemy. No your altenator is probably not bad, test it with a meter by placing the red lead on the positive and black on negative, measure voltage before starting the engine, then again after starting the engine, before should be 11.5v-12.5v, after should be 13.5v-14.5v if these reading are the same on your car all is ok. Hope this helps, let me know.
