Good deal RK!

I did just get finished with Coleman and I don't need to buy any AC's, which is good but I do have to make a choice.

I need to either find an OE 8530D751 AC controller, or do a conversion to the newer set up which would be two new control boxes and thermostat.

I'd like to keep my current set up so I am looking at junk yards now.

At least I don't need to buy new AC's. That would have been a painful buy.

Happy Tuesday Morning update:

So some good news this time. While not ground breaking progress I did just get off the phone with Visone RV and they have the early discontinued AC controller that I need to retain my current system.

Should get my zones back in working order.

New ATS should be here today so I'll have that working correctly by the end of the day.

I did learn yesterday that my Power Gear Levelers might be a bit more damaged than I previously thought.

While Diagnosing I learned that the front left motor had the brake portion completely un bolted to the housing and resting in the boot full of water.

I also managed to break the manual adjuster on the Front Right motor. At this point I am looking at two motors unless these can be rebuilt.

Adding to the list.

Cheers

Update:

I am happy to report some additional good news today. If anyone can remember back on post 58 I mentioned having issues connecting to 30 amp using a dog-bone. Well I finally got to the bottom of why every time I would connect to 30 amp my ESP would fault to nEu... open neutral.

After confirmed I was getting proper voltage to L1/L2 I decided to remove the ATS. The utility/shore relay was really sticky on the right side. Had to apply real firm pressure to get it to move. The left side moved just fine. The Gen Relay was silky smooth. I concluded that the shore relay would get stuck when trying to switch to 30. Since locating a relay to fit an obsolete model was impossible, I decided a new ATS was in order. I just finished the install of the Southwire 41260 ATS. While I am bummed I lost my ESP readout by the panel, and will have to adjust to the insane amount of humming it produces... I am thrilled to have this part of the build resolved and worked out.

Will report back when the AC controller gets here.

Cheers

Congratulations on the positive things happening now.

It sounds like you are not dragging your feet on researching and repairing all the things this coach needs. Continue to keep us up to date.

Nemisus · 03-22-2023, 08:21 AM

Thank you SVT!

I started out committed to ensure all the system in this MH work as they did off the line. The previous owner did some crazy things and a lot of short cuts. My thought was if I can get these important systems working we can take our time and build the home the way we like and use it while we build.

When we bought it the following items didn't work correctly at all.

AC/Furnace (both zones): After removing the ceiling most of the ceiling harness was removed or just severed and left cut. Missing control box for the rear AC and the flame control board for the zone 1 furnace. Just removed for what ever reason.

Interter/Charger: The Magnum Energy failed at some point. That was just an expesive replacmeent but needed.

ATS (would only connect to 50 amp): after several weeks of diagnostic the utility/shore relay was bad. Solved with a new ATS.

Wipers: Had to do a road side fix on this one as weather creeped on is during the drive home. Ended up being easy as a fuse was the culprit. However we did have to a a road side fix on the arms as they nearly came off from being loose.

Most interior lights: This was just a crappy design on the previous owners (PO) end. He just removed all the OE lights, wired in new ones but never tested his connections. He also removed several switched lights so some are always on. I'll get to that later.

Stereo: Another fuse issue, but every man has to have his tunes while driving.

Chassis battery disconnect: Not really sure what caused it to stop but I reset the relay in the BCC and it seems to work. However it doesn't actually disconnect. I can still start the engine with it off. This seems wrong to me.

Tank level readout: This was a bit more complicated but discovered the cause while tracking down the Thermostat signal wire. Apparently a leak in the pass-side cause water to settle inside a coach to chassis plug. The deteriorated the connections to the point of zero continuity. Re-wired and several things began to work.

Water pump for fresh water tank: Another fuse and a broken filter got this running again.

Propane water heater (leaked): Replaced the valve and leak was resolved.

Emergency LP shutoff (was bypassed): This one baffles me. The 5$ toggle at the back fill connection failed. The LP Shutoff switch. Rather than replacing the switch he ran a secondary harness to under the sink and robbed power from a circuit there. There are a pleathera of reasons why this was a bad idea.

I am sure there is a lot more I am leaving out but as of this message the only system to not be 100% is the AC/Furnace zones. As soon as my new/old control box arrives I should be in business.

That last remaining system to not work is the Power Gear Electric leveling system. That one is going to take time but I'll get to it.

Might take a break this weekend but if its a nice one I'll probably be at it again.

Thanks for following.

Thanks for the updates!! Excellent progress! It never ceases to amaze me what some people are thinking when they try to "fix" or "upgrade" RV's, boats, cars, etc....I just scratch my head and think "WTF?????".

Wish I knew something about electric levelers, but mine are hydraulic so I'm not much help there!

Hey RK,

Kind makes you appreciate the small things. I suspect the PO had good intentions but I could be wrong. We found a folder in one of the cabinets that outlined ideas to change and modify. It was from the day it was bought. BRAND NEW and he was already messing with things and removing things.

While I have the 40X floor plan, there is nothing "Theater" about it. He removed all that stuff. Nothing I can't add back but it is a head scratcher.

The Levelers worked well until out 3rd day on the road when a break in a water line flooded the lower basements in the rear. Water then got trapped inside the boots of the brake on each motor. A day later after a long drive it reached 17 degrees in New Mexico at the casino RV park. Didn't think anything of it when I woke and begin getting ready for the next day's drive. The water had frozen solid and when I hit the "retract all" button all hell broke loose. Took me 3 hours to manually raise each and they have not worked since.

The system powers on and beings to work but then goes into error. I suspect there is an issue in the brake/motor of at least wo of the levelers.

I've got a trouble shooter from Lippert just need to find the time to dedicate to it. I suspect it'll be expensive. The control box for this system is 1k alone used.

Gotta love owning a MH. Especially a builder.

Have had problems with my electric jacks, the lights show you what jack is in trouble.
Post your problems

Nemisus · 03-23-2023, 09:18 AM

Hey Basketball,

Thanks for the feedback. I'll try and get specifics this weekend. The other day I went to work on it and I can no longer get it to error. It just says wait but nothing happens.

The Front left leveler is down and I am not sure how it went down. When I looked at it the brake was sitting unbolted inside the boot so I am sure that is an issue. It wasn't part of the original issue though.

I will try and manually raise it so I can get the error to tell me what corners are the issue.

Stay tuned,

Thanks,

I found it best to work on jacks from the control computer mounted in one of the bays, mine is on drivers side compartment on midway point. That is where all the wire goes to from the jacks. (drive wires and sensor wires)
There is power there on terminals. I use wire and alligator clips to drive jacks up and down. Disconnect all jack wire from control board (label all wire to which jack it goes to. The control board is labeled .
The 12v will drive the jack up and down reverse wire and jack will reverse direction.
If you use retract all jack button on control panel and one jack is up already up you will break the shear pin in the jack and that jack will have to be removed and repaired.
All jacks must be at least 10 inches down so that the control panel can see the sensors on the way up.
Use the wire to lower all jacks.!!!!!!
My cheater wire never leaves the MH compartment.

Nemisus · 03-24-2023, 08:18 AM

Good stuff Basketball.

I will give this a go tomorrow. Weather is looking to be favorable so I have plans to be at it again.

Thank you!

Grizzly73 · 03-24-2023, 09:33 AM

Wow, you're making great progress on lots of issues!

Which thermostat do you have in your coach? If it's the Atwood 4-zone CCS, I might be of some help.

Shawn

Nemisus · 03-24-2023, 10:52 AM

Hello Shawn,

Thanks for the feedback! I am not sure what the model is but I'll attached a photo.

I was able to locate an old AC controller that will work for it from Visone RV and it should be here next week. The issue is the rear zone AC didn't have the controller present and the one I ordered was for the newer model Thermostat.

The one I have is pictured on this reply.

Thanks in advance,

Good afternoon iRV2,

Not a lot to report this weekend but I did get around to adding a Surge Guard hardwired 35550 into my ATS system.

Works as in tending. Can't say I am a fan of the 128 seconds delay for it to turn on though. At first I thought it was faulty or I wired something wrong. But as I was reading the trouble shooting and came across the "caution while flashing" section and learned it had this delay. It also can mean there is a fault but both L1/L2 lines light up as expected.

I am also not a fan that the input and output forced me to install it upside down but wont be looking at it often so no biggy. This one is wired for the external remote so I'll order that so I can have a display where the OEM ESP was mounted since it is no longer usable.

Cheap insurance and I'll rest easy when connecting to unfamiliar parks.

Off to attack another part of the MH.

Cheers
