Generator putting out 18 Hz?

The brushes on the rotor slip rings control current and voltage to the rotor which controls output voltage
Nothing to do with Hz, that is strictly rotation speed which is controlled by the governor
Only one winding in the rotor
The stator winding are the poles
One runs at 3600 rpm
Two runs st 1800 rpm
Three runs at 1200 rpm

I have never seen a gas RV Onan three pole 1200, rpm model,
I'm not going to claim they were never made, just i have never seen one

To get 18 Hz you need a dead winding in a two pole running at about half speed, just above half speed

Yes but time it with another clock
Do not use a digital on the generator, need a motorized clock
Ten minutes then shut off generator and check the clock plugged into generator

In generator lingo ???-turn (two pole) 3,600 RPM

18-turn (four poles) 1,800 RPM

12-turn (six poles) 1,200 RPM

Below a 55 Hz (cornering frequency) many regs wll go intermittent meaning their signal to the field isn't continuous.

Even a cheap multimeter will have Hz. And I sure would trust it more than a "meter" on some line monitor device.

When an suspicious value is offered I immediately suspect the measuring device until its measurement can be corroborated with another device.

34 years ago when I assembled a Kubota to a Kato generator, I had a miserable time finding a 12 turn power head that was a 12-turn. And to think anything under 12.5 Kw was available in a 12-turn would have been a pipe dream.

JANDKSUNSHINE Recheck I think you will find the Genny to be a BGE not gbe.

And with that in mind, An Onan Emerald Plus BGE is an 1800 RPM generator. 2 cylinder boxer engine, oil pump and oil filter. So disregard all that info about 3600 RPM generators.
If you don't properly identify the item that failed, all you get is guesses.

Give the guy the benefit of he is new to RV World. Transposing 2 letters
He could be dyslexic we don't know

this goes back to the govenor and how fast is it running

is really running only 900 or so RPM ?

or is there an open winding ? in the stator

or just a bad voltage regulator, messing with the sinewave giving a bad reading on the surge guard

plug in a fan or a clock and see what is really going on

a typical box fan is going to run way slow if its really 18hz
