Not wrong. Here's a simplified drawing of the generator circuit from the V8 manual. Everything is more or less tied together -- either directly or thru other parts.
If you measure the Field terminal, it indirectly connects to ground no matter where you measure it. Measuring generator only it reads thru the coils and armature to ground. Measuring at regulator, it reads thru low ohm resistors or closed contacts to ground. Same with the field to armature. At generator, thru the coils. At regulator, thru a resistor and the coil windings in the regulator.
Unless you have very sensitive measuring equipment, it would be hard to separate things out with readings from a typical ohmmeter.

Field terminal has continuity with field, arm, and ground. This seems wrong, is this caused by the voltage regulator not functioning?
