Yeah it's most likely the alternator, when you had it started did it sound diffrent and did you check the gages to see if the battery was showing lowness? or maybe when you had it started did it sound like a marbul ball was bounceing around i know thats what it sounded like when my alternator shot out. You can always buy a new one and if that's not it return it. but good lucks to you

If you have any kind of multi-meter you can charge the battery and start it and see if it is putting out voltage.

A volt gage is the easiest check. A charged battery should read 12.5-13(?) volts. A good charging system, when running will increase the voltage by about 1 volt. You should be able to see the same effect on the dash volt gage.

You can also take your alternator out and to Murrays, they do alternator testing.
