Answer for USA, Canada and countries running a 60 Hz supply service.
When installed properly, there should always be continuity between ground and neutral because they are bonded together at the service. If continuity is intermittent, something is loose. I would start by checking your bond in the service panel

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Why are the brushes of a dc machine always placed at the neutral points?
The function of brush is to collect current from rotating commutator and supplies the current to external stationary load. The brushes of a DC machine are placed at neutral points because the current in the rotating part drops to zero at the neutral point. If brushes are placed in location other than the neutral points, then the current may be switched off and it causes magnetic field and it may also create voltage spikes and arc at brushes.
Armature reaction in a DC generator?
ARMATURE REACTION in DC MachineAll current-carrying conductors produce magnetic fields. The magnetic field produced by current in the armature of a dc generator affects the flux pattern and distorts the main field. This distortion causes a shift in the neutral plane, which affects commutation. This change in the neutral plane and the reaction of the magnetic field is called armature reaction.
What is the difference between the input bias current and the input offset current?
A: difference in bias current causes the other
Why is the outlet 86 volts instead of 120 in your outlet?
There may be an "open neutral" somewhere either in your breaker panel or in the meter base. Contact a qualified electrician to help solve the problem. An open neutral causes one leg of the electrical service to be "low" voltage, while the other leg goes "high". That can result in premature failure of electrical components, such as light bulbs, electronic devices and electric motors.
Drift speed in a conductor that carries current?
The Drift Speed is less than the average speed of the electron between two collisions. Electrons move relatively slowly along a wire but very quickly between collisions. The electric field (EMF) that causes the motion moves at the speed of light.
