Thank you.
I have a 15A to 20 A adaptor I will try this afternoon. If everything in the RV is "Happy" I will fab in a 20 Amp outlet and then finish it's break in.

If there is information for this genset in this thread; shoot me a link. I do have a scope I can put on the genset to see how "dirty" it is. I assume all non inverter gen sets are a tad noisy

BTW; as was posted earlier; it was only about 1\2 full of oil; and would not start.

As always; a big thanx.

An odd observation.

I used a 15 to 20 Amp adaptor to test this genset. If seemed to run my 15K AC AND microwave with no issues. (Run voltage was staying at 125 VAC)
I swapped the dual 15 amp plug for a single 20 amp. I connected the two legs in the same manner and took the extra step to replace the wire at the junction box under the dust cover from 14 gauge to 10 gauge.

Now the Micro will not start but the AC does.
Measuring from hot to neutral = 125 VAC, Neutral to ground 60 VAC; ground to hot = 65 VAC

So; I have seen a post concerning this earlier on a 1200 watt genset.

"neutral on the generator is not bonded to ground

when measuring AC voltage you will measure 120 from neutral to hot

and aprox 60 volts AC between neutral and ground OR hot and ground

this is normal for the generator

"
Is this normal? I assume these are 60 VAC windings but in phase.

Thanks as usual.

it (1) 120v winding, it is not electrically/physically connected to the generator frame

you are dealing with magnetic fields & electrical "POTENTIAL" volts is the term used to describe 'electric potential' OR force/pressure

there a voltage potential/differential between the frame and wiring/windings induced by the magnetic field in the generator heat

think of it like the heat radiated from a hot engine block , air around the block is warm, but it won't burn you, stick your hand on the exhaust or block and get blistered

the 60 volts measured is like that radiated heat , it's not physically electrically connected to the genny head, your measuring more magnetic induced potential than real power, if you were to accidentally touch the either the hot or neutral while touching the FRAME, you would likely receive little or NO shock,

that's why you do NOT bond the frame of the genny to the neutral, IF you did that, the voltage would be a real 120v between the hot & the genny frame, a lethal situation if the portable tool/light/etc shorts out and you touch the genny frame, bam bad shock or death
