Onan genset removal question

So I found the 2 screws that were holding in the circuit board, they were right in front of me the entire time but I thought they were for removing the outer case of the genset....apparently not. So I removed the solenoid and circuit board (thanks to everyone's help!!) found out where to remove the green and white wire (easy) but the black wire runs into the other side of the generator, looks like it might connect to the start switch. I'm SO CLOSE (i am fine with cutting the black wire and splicing it later since the splice will be inside the generator and not really exposed to the elements. HOWEVER, now i'm thinking is this really the best way to get this serviced? or would it be better to leave it in the RV and have a service guy look at it? I would hate to take it out and have the tech say "gee, I wish you had left it in the motorhome"......Like I said earlier the reason I need to remove it is because I ran it without oil so i am sure it will need some extensive work.

DrewE,
That's exactly what I did, I made some ramps and drove backwards on them so they wouldn't be in my way. I have a floor jack for the final removal if I decide to take it out. After measuring I should have a few inches to spare (I hope).

I Have a K series generator that I removed just a couple of months ago. I used a motorcycle jack, which made it quite easy. As for the wires, I found out that they should be taken off at the junction box. There is no other way, since they are part of a wire loom that goes to another part of the generator, so don't pull on that end of the wires too hard. Make sure you also remove the muffler before you lower it, otherwise you will crush it. The mechanic will probably thank you, since it is sometimes a tedious job. He can also bench test the generator easier once it is out and can supply it with gas from a gas can. In fact, my son and I lifted the generator and placed it in the truck of our car and took it home to my garage. I had my generator running in my garage. It is not as bulky or heavy as it seems.

I wish I had a junction box, it would have made this so much easier but the wires running into my generator are enclosed in heavy rubber conduit that runs from the generator which sits just behind the driver all the way to the rear of the motorhome where goes inside the RV, no junction box unfortunately.

The black wire connects to the AC circuit breaker on the generator control panel (unless they've changed things, which I rather doubt). It kind of snakes around the bottom pan of the generator to get there.

Thanks DrewE, removed the circuit breaker and found where the black connects!!! so now im all set to drop it but after measuring I found out that my homemade ramps only gave me about 6 inches of lift. With the floor jack and piece of wood on top of that plus the generator height I need bigger ramps. So unfortunately removal will have to wait for a week or two. Thanks so much for everyones help!!!

Its out & in the shop, like I said I ran it with no oil so we shall see just how bad the damage will be $$$

OUCH!! You are NOT the first to lose a 4KY to low/no oil. You also validated something that comes up often: Searching for Oil Pressure or Oil Level Sensors on any 4KY made in nearly the last 20 years is fruitless - They Ain't Got'Em!
ONAN offers a replacement Engine for these. Not cheap, but cheaper than a new genset. We had a thread YEARS ago (maybe a Decade..) where an OP bought the replacement engine in a crate and swapped it over himself. I might do that, but then again I might not. The same thing could go wrong and blow the new engine. Covered under a warranty if a shop installed it, Not covered if I installed it, even if the work was done perfectly correctly in both cases.

Thats exactly what i was going to do, swap out the engine part (which as i understand it there is an engine part and a generator part). Still waiting on shop to contact me about what kind of damage i caused.....
