1997 Ford Mustang • 150,000 miles

My mustang has been sitting in place for about a year, the window was busted and everytime I tried to cover it up the wind blew the plastic / tarp off. (Live in oklahoma, very windy.) I tried to jumpstart the car the other day and after it was hooked up and left charging for a bit, I tried to start the mustang. This is what happened: when I turned the key it clicked, and the belt moved a bit, then stopped, then moved a bit, then stopped. Do you think this is a problem with the battery/alternator/starter/something else?

The battery is too dead to do the job, try removing the battery and have it charged/tested. Replacement of the battery is a possibility.
