Default Battery Light stays ON when car is OFF

I had a weird issue over the weekend. I took my '64 out for a ride and stopped at the parts store. As soon as I turned the car OFF to go inside, the battery light came on, and stayed on. So, I started the car, shut it off again and the light went out.

After leaving the parts store, I drove home, parked the car in the garage, shut the car off and the battery light stayed on again. I disconnected the battery, and reconnected it, and the light stayed off.

I didn't find much in the service manual about this. I haven't done much troubleshooting yet, but could it be the battery? The alternator? The regulator?

I have never had this happen before. It had been a while since I drove the car and the battery is old, but it still cranks the car over without a problem. All the harnesses are new as well.
