Good luck and let us know how it goes!
EDIT? I notice the 2002 Horizon does not show an inverter but converter only!
The 2004 vectra came with inverter charger, so there will be some difference in the two RV.
Okay, got to pick a place to start and decide which way to go!
If you are set up and can plug into power with the cord, we might first make sure that power is getting to the converter, and also the converter is making the DC to send on to the breakers, so I snagged a part of that drawing to help find a semi-handy looking spot to check.

From sheet two of this drawing if you want to go to full picture as I cut a lot out to fit!
If the converter is getting the AC it needs to make the DC, I expect to hear a hum if quiet. But if you have a meter and find this stud with two number 6 black wires, that might be a place to check for 12VDC coming out of the converter that feeds most of the breakers for inside things!
Winnebago stamps ID on their smaller wires and drawings. See the red marks? If we find the ID on wires, we can then go to this list to get the from and to locations of that wire! A long string of letters and numbers but the last 2-4 are the ID.
The breakers or fuses are often drawn looking from the back so mentally turn it around to get the location when looking from the front!! In that way, you can often find the fuse labels on front that may tell you what it feeds but also the chart can tell you if the labels are missing or not as complete as we need.
What the list and ID do is let us find where to expect something like voltage or ground on any specific wire.

Basic idea is that we need to see 12VDC coming out of the converter when we have 110AC going in! Or is the 110 not getting to the converter? A wire loose at that isolated stud could be killing most of the inside 12VDc things! Or there may not be any AC getting to the converter, so we might need to chase it in that direction.
The way Winn does their drawings puts the 110AC on a different drawing set.
All wiring drawings here:
But on the noise you hear, that doesn't sound right as the relay/solenoid is a big heavy duty thing that should just thump as it moves and holds. I see the switch as top left switch at dash.
I know this circuit as common one they used for a long time. But in this drawing they really missed what they were doing.
The idea is kinda simple after we know what to expect. When we push the dash switch, it should send 12VDC down to this solenoid that is often near the batteries but I have not found it on your RV, yet. Battery on LR goes to the small lug on the solenoid and they did draw it like it looks but not right on wires. that bat. should go to the coil inside to pull/operate the contacts to close. There should be a big battery cable on each side on the big lugs. One goes to coach and the other to chassis batteries to connect them when the contacts close!

Not going to work with no cables on it! But I don't think of any noise other than it often makes a "thump" as it closes those big contacts. I think this will also be closed when the RV engine is running as a way to get some charge back into the coach batteries after we might run them down camping. But I've not see that, so just going on what other Winnebago do! Don't trust that guess until tested?
If you can hold a hand on this solenoid while somebody pushes the switch or if they start the RV, you can often feel it thump. That should send power from the engine alternator over to the wiring for the coach and the inside lights and such should start to work if things are set right on the battery disconnect switch, etc.
On the inverter and converter questions, it is often a case of names changing as new stuff is used. Inverter use 12VDC to make 110AC, while converter do just the opposite and use ac to make DC. They started with converter to make DC, came up with wanting to make AC, so they added inverter as a stand alone item. Eventually they combined inverter and converter under the same cover and now we get all kinds of different names and versions of doing the electrical. You may have an inverter as a stand alone unit somewhere but I have not seen it yet.
Way too much info?? I better quit before both our heads split!
Also, I received a call from Winnebago, I was told if it is a 50 amp service (which it does)then it would only have a inverter. It is mounted in the Driver side compartment by the rear t
