Hi everyone, I got this Sunflyer from my next door neighbors last month, and the price was right.......free. But, as we all know, no RV ends up being truly free. This one had been sitting since about 2011. My neighbors were getting ready to go on a trip, and the wife wanted to be proactive and fill the fresh water tank, except she accidentally filled the fuel tank, instead. Thankfully, the engine was never started, and the water was drained from the fuel tank. They never went on their trip and the Sunflyer sat ever since, under an elm tree. Sadly, my neighbor's husband passed away in 2018.

In May, we had a terrible windstorm and a couple of branches fell on the motorhome. Miraculously, there was no damage done. My neighbor's son lives with and takes care of her, as she now elderly. The son is a nice guy and we get along well. He asked me if I would help him clear the branches off of the Sunflyer, so I brought over my chainsaw and got it done for him. I then asked him what he was planning to do with it, and he asked me if I wanted it. Given I got divorced last year and the ex got the Monaco motorhome and then promptly sold it for less than half of what I put into it, I quickly said yes, not really caring about its condition. We hooked it up to the son's dually and towed it next door to my place.

It took me four hours to pressure wash 14 years of dirt and crud from the exterior and another four hours to do a precursory vacuuming of the inside. I have since been working to get the electrical systems back online. Again, miraculously, the original Coleman TSR Mach 3 A/C still works, despite a cracked-to-**** shroud that allowed a bunch of leaves and dirt to accumulate. The only electrical that doesn't work is the bathroom ceiling light, probably due to water intrusion on the roof, as well as the aisle lights.

The roof will need to be completely rebuilt, which I've done before on a previous slide-in camper I used to own. The interior will be carefully gutted and the carpeting will be replaced with LVP, except for the driver's/passenger area, which will be replaced with new carpet. The original Audiovox SPS radio works, however the quartz clock burned out about an hour after I put power to it, and the cassette player doesn't work. I was able to find a NOS Audiovox electronic tuner cassette player on eBay, which will work for now, until I'm able to get a Sony CarPlay system for it, but that'll be down the road.

For now, here are pics of the coach as I got it and after cleaning it. This will be a project that I'm taking my time to do. I'm retired, so I'll do a little bit at a time and then post the progress.

I wanted to add that the email address that KirbyRVA posted in his "Service Tips" thread in 2008 is still 100% valid. I sent an email off to Winnebago and received all of the diagrams, wiring, plumbing and layup (construction) that they had for the 1984 Sunflyer. With the exception of a couple of minor running changes, everything is spot-on accurate.
 
Oh MY! Shades of the old days when I was interested in that sort of project! My first few RV were of that sort and it looks like you have the right start to getting it done!

Finding info is a biggie, so that brings some questions as I am also retired (kind of?) and that leaves me doing lots of weird things while I wait for other things!

So did you get lots of electrical drawings on the those light problems?
I tend to like the electrical questions and volunteer to help sort them if needed?
But I don't even pretend to know the whole story, so especially like drawings to give me a guide!

Sounds like a good plan for a good project at the price!
 
Hi Richard, the gal from Winnebago was kind enough to get me every single electrical, plumbing and layup diagram available for the W/ICN22RC, which I am attaching for everyone's use.

Happy Sunday everyone. This weekend was very productive. Yesterday I got the battery compartment cleaned up and looking tidy. I also took the time to wire wheel the connections, and this made a big difference in how the electrical responded. This morning FedEx showed up with the new Coleman Mach replacement shroud, which I installed, but you can definitely tell that the roof is sagging from the water damage. I then turned my focus to the engine.

Today was the day to kick this pig and get her going, and I can say that the result was, as I say in the video, very anticlimactic. I got the plugs out yesterday and put Marvel Mystery Oil in the cylinders. This morning I turned it over by hand, and it spun over three times with zero effort, so I put the plugs back into it and disconnected the leads to the dizzy. I cranked it and the oil pressure came right up to around 50 psi, which really surprised me.

I then reconnected the dizzy, poured some 128:1 2-stroke fuel in the Quadrajet bowl, through the vent tube, and turned the key.....and it fired on the first try. There was no smoke coming out of the dual exhaust, and the high idle kicked down, although because of open vacuum ports, it idled a bit high. I was also able to put it in all the gears, and the TH400 shifted firmly but smoothly and it moved a few feet each way.

Here are pictures of the battery compartment, as well as the two videos I took this morning:

OH my! A bit of corrosion?
Looks like you know what to do for that, so I thought to mention a common issue on some of the older RV.
This solenoid (or relay?) had a bad habit due to the mounting screw or bolt getting loose or corroded!
This is a big thing still but they have made it somewhat better by adding a second wire to bring ground as well as battery to operate this relay.
But it is still a common problem, so good to keep in mind, maybe?

It does two different things for us. One is that it has a couple different places in front to pick up 12VDC . First one might be what they call ignition hot. When we have the key on that point sends 12V down to go through the coil in this solenoid and to ground through the metal case and mounting. Operating this closes contacts to connect the chassis battery and alternator on one big lug through to the coach batteries on the other big lug.
That lets us get some charge back into the coach side as we drive!

The other use is when we push a dash switch when we need a "jump start' without getting out jumper cables! There should be a momentary switch somewhere near the driver that operates this solenoid while we hold it as we start the engine!
They sometime called this an isolator as it also cut (isolated?) the connection when we are not pushing the switch or engine running! That lets you connect them when wanted but isolate them when we don't want to run both batteries down while camped!

A recent post about this part of a newer RV:

But this might be a good time while cleaning to make sure there is a good solid ground at the mounting screw as this stops working if that ground is lost!
Good looking job of cleaning most connections but don't overlook that one where it mounts!

Carry on with the project and enjoy the new tricks!
 
Hi Richard, I am quite familiar with the Trombetta solenoids. I know this one may look like it's spent a few decades at the bottom of the lake, but I did remove it from its mounting location, and the metal still looks good, so I reinstalled for now. It will receive a new one down the road, and the battery compartment is going to be wire wheeled and will receive a coat of POR-15, and the all of the heavy gauge wires will be replaced with new red and black wires. I've seen people ask why the wires are all black, and the only answer I can come up with is cost. My main goal was to ensure I had good contacts, to see what works and what doesn't...before I had no life from the ignition, and after it fired right up, and so far, only the bathroom ceiling light is non-op, probably from corroded contacts, due to water intrusion, but all of the lights are getting replaced with LED, so it's a moot point.
