Given the simplicity of our typical vintage automotive electrical system, this tells me that you either have something "ON" (drawing an amp load) or you have a short . . . also drawing an amp load. Given that you don't have a computer or anything that should be on, this situation will draw down your battery after some period of time. After you've checked the 'obvious' things (like brake light switch, lights, ignition switch, etc), then I'd be checking the components in my charging system.
