Jonesky has the right idea. This won't always work on newer vehicles with more electronics, but works great on 72 and before. Another quick fix to keep you driving is one of these linked below (can get them at the local parts stores). Just a quick way to disconnect your positive cable while you are at work/overnight, etc until you can get the problem corrected. Also, maybe I missed it in your post, but have you had your alternator checked?
