Most vehicles that were still using positive ground electrical systems at the time, were switched to negative ground systems by the mid 1950's. The last vehicle I recall still using a positive ground system, was a 1960 Metropolitan Coupe.

I doubt Iceman is old enough to need to worry about remembering that.

Well, I took it right down to the frame last night and went over every wire, popped every connector and coated with dielectric grease, then pulled the fuses and did the circuit tester thing. The 30 amp primary fuse showed a ground so now I'm really wondering... Anybody have any more ideas?

I'd start disconnecting them one at a time.

I've got a feeling it is the starter relay. There is a loud buzzing noise and a pause prior to the starter rolling over. But if that is the case, why would the battery still be going dead when the bike is off? Would that relay still be feeding power through to the ground even with the key off?

Pull the relay and see if the drain stops. The relay may or may not be the problem, but you can buy a new one from most auto parts stores for about $5.00.
