Searching for a drain. In my stock 1946, there are 3 terminals on the ignition switch. One goes to battery, one to coil, and one to "Ignition Switch (Gauge)" With the key off, should that terminal going to the battery still be live?

Yes, the battery post stays hot so it can provide power to the coil and gauges when turned to the "on" position.

Bill, Disconnect the battery negative cable and connect the positive cable to ground. Connect a test light between the negative battery terminal and the negative battery cable by attaching the clamp to the cable and touching the pointed probe to the post. If the light comes on, you have a short circuit somewhere. If you have an alternator, start with disconnecting it. Then start disconnecting wires until the light does not come on. Start with disconnecting the battery wire to the ignition switch,I believe that it is a yellow with black tracer (I am having problems reading the wiring diagram). That will isolate the ignition switch and everything fed from it.
