Default Great! GenSet is running! But...

Great news!

After replacing the points, condenser, plugs and oil, as recommended by some forum members, the GenSet beautifully run after few attempts!

The Genset seems to be running fine:

But the thing is, I mounted it back on the RV, and there were no powers being transferred. Weird.

I took a multimeter and measured the voltage across the 3-wire set going back to the RV, as they seemed to be the main power cables from the Gen. The reading were as follows:

White to Black: 111V
Green to Black: 110V

I couldnt find in the service manual what these numbers should be. The Genset is producing volts, so I am not sure if the problem is at the circuit breaker inside the RV or if 110V is still out of spec (too low?)


Any sugestions?

Here are my specs:
Model: 4BGE FA 26101 F
Serial #: F880129323


And here are some pictures:

Here is the wires that I checked the voltage:



And here is the circuit inside the RV:








Thanks again in advance,


BB

The right side of the "inside" panel you have uncoverd is 12 volts DC, you should not have AC there anyway. Look under the other side and find the other end of that blue flex and your black,white, green wires.

Be sure to check the simple things first. Does your RV have a generator pigtail that has to be plugged in, or a shore power/generator switch?

Here is the other side of the power panel:

It says it has the 120 VAC circuitry.




At the same time, is the 110V coming out of the GenSet wires withing specs? If so, then i guess I have to make sue these 110V are actually reaching the panel, right?

Not sure what you are talking about, but I know the Genset has never run inside the RV since I bought it (this spring) and I do have a power cable that I connected to outlets when I go camping, and power works fine inside.

Are you saying I could have a switch somewhere?

There is likely either a switch to choose between shore power or generator power, alternatively there may be an outlet connected to the generator where you plug the shore power plug into to run on generator power.

110 volts is close enough for troubleshooting purposes. Obviously somehting is keeping power from reaching the panel. (The 30A breaker appears to be labeled as the main)

Yes. Or a receptacle powered by the generator that your power cord will plug into. (Where does the blue flex shown in your first pic go to?)

I assumed the blue flex, with the 3 heavy gauge wires, were going into the control panel and from there to the camper.

Not sure whats going on here.. but i guess i need to investigate behind the panel and confirm these 3 wires are coming to it... right?

Finding the other end of the blue flex can't hurt anything. There is (or should be) something that prevents the generator and "shore power" from being fed into the panel at the same time.
