A person has to be cautious around electrical production units that manufacture their own sine wave. There is no such thing as ground merely connection to stator winding ends. Earth ground is useful in single phase transformers and non Delta connected three phase transformers.
An issue I see with an electrical device that is broken is that it is deceptive. The "dog bone" here is not uniquely dedicated to the Honda. It can be connected elsewhere and under the wrong conditions the missing ground can prove deadly.
As an old broken down EMT 2, I have been on scene to see electrocution victims that seemed to be untouched except for an arrested heart. Electricity is flaky. It can take different paths through the body and if it decides to go through the ventricular section of the heart it will absolutely instigate ventricular fibrillation. Death. Left leg through left arm is the most risky electrical path a shock can take. Two-hundred watts is more than enough to cause ventricular fibrillation. Please please, respect this...
