Don, Do you have this repair manual for your system. There is a 50 lb. pressure valve in the system and if its malfunctioning, that could adversely affect the ability of the jacks to raise the coach. http://www.hwh-europe.com/download/ml13514.pdf Page 17 shows the wiring / Plumbing for the straight down jack system. If this the style you have. This is the link to the different parts manuals. http://www.hwhcorp.com/HWH_table_of_contents_3.html Regarding getting parts from HWH, finding a service center or tech. might be the only answer. Rich.

I have friends that have changed out there OEM refrigerators to the home style. Some just run them when on shore power and things stay cold while traveling up to 8 to 10 hrs. They do not open them often and that works for them. Others have pure sine wave inverters and run the refrigerators while on the road. The alternators keep the coach batteries charged so whenever the unit calls for cooling everything works fine. Do you you know what type of inverter you have? I 'm leaning towards to pure sine wave unit. The older inverters where modified sine wave units. You might want to ask you rep. what his reasoning is regarding running the refrigerator. You could list the model information for the group and then we could see what the power requirements are, and with the inverter information and size of your coach battery bank could offer our thoughts. Rich.

Dave, sounds like a plan ! Thanks you the update. The one other trick to use on the black tank is to put some clean water in the tank, like you mentioned and add a bag or two of ice using the pot. when the Toilet sets directly over the black tank it's easy to get it in the tank. Then drive the coach around for awhile, the ice cubes act like little glaciers and scrub the bottom of the tank. Nice thing is they melt, they take the material loosened; out of the tank with the water. I use one of the clear couplings at the dump valve so I can see what is being discharged, Ya! its a little gross; but you can see when you get clear water. Also, can use one of the wands that go into the tank, I like the ones with the spinning heads to do the job when It's time to see how well my factory tank wash system is doing. I'm scratching my head a little regarding the gray tank. The fact that you had the nest in the vent might make the tank drain slower, but its not emptying ? Strange as it sounds, wounder if there is something like a big hair ball in there. Tom mentioned the possibility of some material getting into the tank when it was install. Thinking if that was the case the emptying completely issue would come an go, but one would think the hairball thing would act the same! Rich.

I had a similar issue with a different size. They where not in stock at the location I was in and the other branches where out of the size also. They had an order arriving in 7 to 10 days. Just the way the load of tires was scheduled to arrive. Shipping tires between outlets is common, but shipments from the warehouse are not just to one dealer, but a number of them to off set the cost. The tires could have been shipped, over night, 2 days what ever, but I would have had to pay the extra shipping. The same goes for any item one orders on line or from a store. They can get the items in most cases, but the buyer will need to pay for the shipping. The large tires are not stocked in large numbers, because of the amount of money tied up by the store and the rather limited number of buyers. Rich.

David, By chance do you travel with young children? Did something get put down the toilet? When you raise the front and it drains well, that sounds like that puts the drain point higher then the back of the tank, is my thought correct ? Thing is if that is the case what would be in the gray tank. With the jacks down will the black tank drain better? Could you post the Make, Model and Year of your coach for the group and how long you have owned it. Rich.

Pretired, Take a look at this link. Select the year and model of your coach and download the wiring information. the information should lead you to the area of the switch and give you the wiring circuit(s) covering you 12 volt system. http://www.winnebagoind.com/diagram/Wiring.htm Look the information over and let us know how you are doing and get some additional help if needed. Rich.

Pretired, Welcome to FMCA ! When you mention everything works works when connected to shore power, does that include the AC Unit(s), refrigerator, and the 12 volt lighting? Should these items not be working the only thing that would prevent that would be the lack of 12 volts from the DC fuse panel. From your post it sounds like you loose the 12 volts as soon as you unplug from shore power. Is the disconnect switch for the 12 volt supply turned on? Some coaches require a switch to operated manually to get 12 volts supplied to the buss when not connected to shore power. Rich.

Thanks Allegiance !! Things keep changing, but the general information about frame length and cut angle is still good. Along with some of the other points. The source of the chassis used by the Coach builders tends to fallow the best bid for the next order. MIHO also, Putting them together over the years was always interesting. Then the interesting day when all the envelopes where opened. Rich.

Generally they are just red LED's which are polarity sensitive, meaning the plus and minus connections need to be correct for them to light. A picture of your set up and light would be helpful. Rich. Edited, 8-7-13 No reply regarding your question, so you need to know that there is a resistor / diode circuit the protects the solar panel from discharging the battery and a picture of the damage would help evaluate the damage and what item(s) or connections where compromised.

Good morning Derge, Welcome to FMCA! Could you list the Make and Model of your EMS system just to make sure I'm on the same page and I will see what I can find! This is what I'm thinking in the meantime: Does your EMS panel problem show up just on Shore Power and or when the Generator is running ? Do you have the owners manual? Control board Connector J6-- Pins #3 and #1 are used to inform the system of the presents of 120 or 240 volts AC. When the generator is running there is 12 volts DC present at Connector J2----Pin #2 on the control board informing the system that power is being supplied from the generator. When working on the system connections, Make Sure you are disconnected from shore power and the generator is nut running. Also its a good idea to turn off the inverter, to eliminate any 120 / 240 volts from the system. The only item that I can not really ID is connector J6, all the other connectors are clearly labeled. Rich.

The fallowing link is to one of the better written articles I have come across, that covers the chassis under a coach. I'm not being pro Vender, just think items covered are viable considerations one can add to there motorthome choice. Some useful information when pondering the what coach issue. http://betterrving.com/rv-chassis-what-lies-beneath/ Rich.

Gramps is this the size of the seal you posted the link to ? Rich

I was looking for some different Workhorse information when I ran into this information. Found some information on file that covers Workhorse. If you have questions, please post your specific chassis information including Year and chassis model numbers. I will try to supply the requested information link. Rich.

Hi Gary, Looks like you coach is built on a Freightliner Chassis so with the last 6 numbers / Letter is often the first part of the 6. They should be able to send you the chassis wiring, and electrical. Plus the Air Brake plumbing. What Cummins Engine do you have ? With that information I can send you the link for the Engine oil and filter intervals. The other item you may want to ask Freightliner is if they have the fluid and filter interval information on the Hydraulic cooling and power steering systems. The Coach wiring would have to come from Coachman. Like Herman mentioned. Rich.

Hi Jurica, Welcome to FMCA. Like DD mentioned, you probably will need a Battery as the main source of 12 volts. Unless you have a larger solar setup on your coach and when the sun goes down your refrigerator will shutdown. Rich.

Sounds like the throttle position sensor under the pedal or the wiring in that area. Just wondering if when you came back from your trip, if you vacuumed the coach and just hit or bumped the wiring harness behind the accelerator. Like DD mentioned. If so that is where I would start looking. Could you list the model of your Cummins, Like an ISL or ISM for the group. Thinking you have a harness behind the pedal with 6 wires, 3 for the Accelerator and 3 for the Idle on switch. The idle switch lets the ECM know the peddle is not depressed and signals the engine brake to engage if its turned on. Rich.

Leo, Thanks for the feedback and information. Happy and safe travels!! Rich.

Scott, the switch is most likely made by Carling. Check out this link. http://www.mouser.com/ProductDetail/Carling-Technologies/V6D2GHNB-AAC00-000/?qs=TJJUft5dbNfH1tQj0XylcA%3D%3D&gclid=CLa11ZDP4bgCFY2e4AodFmAA7A Look at the bottom section, other people also bought these. You will see the stile that closely matches yours, but not one picturing the generator symbol. Should you find out that the switch is a Carling, then look at the information on how to remove the top portion and attach it the a new bottom or the actual switch portion of the unit. The bulbs burn out and its been awhile since I have used them to build items, but you might be able to just buy the lamp for it. Rich

Bluegrass, Welcome to FMCA ! The Switch failure is rare, can you start your generator at the generator? Could you post if your coach has a Gas or Diesel Onan. There is a Diesel switch listed at this link. Yours maybe different. You might be able to contact coach manufacture regarding a new switch. http://www.electricgeneratorsdirect.com/power/cummins-onan-remote-start.html?gclid=CPinqcKl4bgCFZSY4AodmTYAJw Rich.

Don, You mentioned the Year of the Coach. Could you post the Make and Model of the coach for the group? Rich.

Thank You ! that fills in a gap, between the regulator and the orifice size; helps understand the relationship between the two. Rich.

You are correct DD, but a pressure regulator setting of 9in. would reduce the flame and a setting of 13in. would increase the flame. That to me means the pressure readings relate to the flow rate, so its a direct indicator of the flame size the way I look at the reading. The regulator settings for the water heaters and furnaces set the flame size, where on a stove the burner is set by the burner knobs. Placing a regulator with a 11in. pressure setting in the gas line of a grill before the flame control regulator that normally controls the low to high setting, will limit the flow so after reaching a flame size between low and medium, one can increase the setting to high and the flame size will not change in size. Rich.

KMiller, Welcome to FMCA. Think you coach is equipped with the RVA System. The link below will get the information regarding the operation of a 3 point leveling system. You can read over the information. They do a better job covering how there system works then I could do. Like most things there are pros and cons depending on ones point of view. http://www.rvajacks.com/ Rich.

Hi Tom, Welcome to FMCA ! Just finished doing some upgrades to the computer software and opened the the forum. Looking at some of the sections and threads I noticed that there was no responses to your post. Did you get an answer to your question ? If not could you post the Make, Model and Year of your coach for the group. Rich.

Phil, Water column is in reference to how the output pressure or gas flow is measured. Brett mentioned the manometer and this is the tool / Meter that measures the flow rate of the regulators and the standard is in inches of water. Like a air pressure gauge is used to check tire pressure. Most gas regulators for RV appliances are set at 11in. of water or as DD mentioned about .25lbs of air pressure. Pressure gauges do not measure things very well at the low of a pressure. Rich.
