Default Finding a short in a 1965 Mustang

I have a 65 Stang and I am curious how to trace to find out where a short is in my system. Usually, I can leave my batter connected for one day before it just dies. The battery is only 2 years old. I seem to go through batteries as well, every few years. (so its a battery eater). Has anyone else have any ideas on this?

Usually, I drive it in the summer and fall, and store it, for the other seasons. I do usually unplug the battery when it sets.

I have had it where I drive it for 5 mins to the gas station, and then I stop and It will not turn over after I fill up. I have to wait a few minutes until it will start or use a battery booster.

Short in old systems can be a real pain to find. It's tedious work, especially if you have to start tearing into the harness to find it.

Discinnect the positive cable from the battery. Put a voltage meter with one lead connected to the battery, and the other to the cable. If there's a power draw, it will register as voltage on the meter. Start pulling fuses until the volt meter reads 0. Then track that circuit through until you find the short.

There are a number of circuits that don't go through the fuse panel. Like charging and starting.
