the large plug is pluged into the outlet inside of the the little door on the left hand side of the coach.
I am not sure about the generator breakers. That would be located on the generator?

Turn all of the breakers completely off and then on again.

OK, Get out your meter and set it to read 200 VAC. Remove the breaker box cover and read the voltage between neutral (the white wires) and the input to the 40 amp breakers. There should 110 on both of them.
Give us the readings and we will go from there.

Though not common, breakers can go bad. If you have 120 volts at the box, check on the other side of the breaker as well.
When we built our clinic, the electrical inspector made us put another electrical box in that used old fashioned fuses to power the surgery room because they did not want the mechanical breakers for critical circuits. Don't know if that's common, but it's what we had to do to satisfy the inspector back when.

Is this a coach electrical system problem or a generator power problem? It would be good to know... before jumping on stuff. (Known as shotgun troubleshooting.)
-- Does the AC power system in the coach work when plugged into shore power? (If not, Reset all the breakers inside the coach.)
-- Less easy but do-able with a GM upfitted coach, is there AC power from the generator at the power plug in the utilities compartment? (If no, check the breaker on the generator itself. We are Ass-U-Me'ing that you have the original Onan power drawer.)

yes, the po showed me that everything was working with the shore power hooked up. ac, fridge, etc.
I do have the original onan. today I will check the breakers and the voltage

You should read 120 volts to ground from either terminal with the generator running. If the reading is 2.6 to ground you have a problem with the generator. Reading across the terminals will only tell you that there is a poor circuit breaker if there is a reading under load .

can you confirm in the first pic if I was using the right range? if so it was reading 2.6 to ground on the white wire and 0 to ground on the black

The readings you are giving us make no sense. You stated in your first posting that you had voltage on some of the breakers and some things work correctly. Now you go back to the generator ans tell us that there is only 2.6 volts there.
I'm not sure why you are in the the generator breaker since you know power is coming out of the generator. Also I'm not sure why your reading there are incorrect.
Please go into the breaker panel and read the voltage coming into the two 40 amp main breakers.

Sounds very much like the same problem mine had when i first got my coach. Turned out the bride rectifier was blown and had been reinstalled incorrectly by the previous owner. That would most likely be the next best thing to check as its an easy fix if that's the problem.

sorry i miss understood where you asked me to do the readings. Also I am not sure if power is coming from the generator as the lights and water pump can run off the battery.

I am really confused at this point.
Do you have anything (120 VAC) that runs correctly off of the generator?

sorry for the confusion. as far as I can tell the onan does not power anything.

OK, Ignore anything I have previously posted on this topic. I was trouble shooting a different problem.
If you have no voltage at all out of the Onan then you are on the right track measuring at the CB. Now that you found nothing the at the CB you need to back up and look in the generator itself.
As others have said, the bridge rectifier or the brushes and slip rings are a good place to start. Replace the rectifier first. It is an easy job.
I'm sorry I initially lead you the wrong way on this.
