It should not have continuity between neutral and ground. Take a new one that is not connected to any wires. An ohm meter will not show any connection.
When installed there will be a circuit but it will flow through the neutral and ground wires clear back to the service entrance. That is where the circuit completes.

The neutral is the return path and has the exact same (should be exact same) current at the hot. It works. The ground should not have any current. It does not work. It is a storm drain. If there is a fault it conducts the fault current and helps the circuit breaker blow. The only place you can treat them the same is at the service entrance where there is a ground rod.

Then normally those two are bonded and the ground bar goes to the building entrance ground rod. Any bad connection coupled with decent amount of current causes voltage differences. Bonded only at the service entrance and separate at sub-panels; that's important. Also worth considering: there was a time when separate ground conductors wasn't required and it was OK to use the metal conduit itself as the ground path. This is no longer allowed because over time conduit fittings can loosen and make the ground bad, possibly intermittently. ~Seth -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team. -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
