A few years ago my thermostats bit the dust and I installed new ones acquired from Newell.  I admit that their schematic left a lot to be desired.  I have been curious for some time that my rear A/C system does nothing when set to low fan.  However it seems to cool fine when set to high fan (two compressors).  I finally got around to checking the amps going to all four A/C capacitors.  All four have 124 volts available to the control board, but the incoming amps for the rear number one compressor only draws 8 amps while all of the other three draw about 11 amps.  The draw going from the control board to the number one capacitor is only 4 amps while all of the other draw about 10 amps.  I am embarking on the installation of high capacity relays, and want to be sure everything is operating OK.  Any suggestions as to what might be wrong would be welcome.

Has anyone ever had work done on their fuel tank sending unit? I just bought this rig and the tank was full when I bought it (thanks, Jerry). At that time the gauge registered about 7/8's. Drove it about 350 miles home and it read 1/4. Running the engine the other day, the needle was barely off empty. No big puddles of diesel under the coach, so I'm assuming the sending unit is faulty. Does it use a float or some other form of measurement? And, as an aside, there is a small black knob in the upper left corner of the tank. Can anyone tell me what it is before I find out that it's the tank dump valve? I don't have a picture yet, but I can get one.

I have a full propane tank.  Detected a very slight leak at the main Rego style valve.  It seems to be the valve stem packing.  Has anyone changed the stem packing without releasing the contents of the tank.  It would seem that by removing the stem handle "wheel", and removing the packing nut with the valve shut off, one might be able to replace the packing.  Not sure if this is possible, or where to get new packing.  Any suggestions would be appreciated.  Rooster

When I bought this coach, the PO said it had no safe, which I thought unusual but took him at his word.  Then today, I was looking at the original plan and noticed there was a safe designated, at least in the plans, under the entry step.  
When I replaced the carpet under the step cover, I remember there is a safe sized steel box in that area, but I didn't notice any openings, then again, I wasn't looking for one either. 
So, if there is a safe there, was that a standard location for classic Newell safe's, and/or can anyone tell me where the access point is?

A Newell parked near us at table rock ozarks RV resort.

Have a 2000 45' Newell #553.
I need to replace the circuit board for the Thermometer that measures the outside and tankage area temps. It is a 2 button (one that is on/off the other alternates between the outside temp and the tankage temp). It is located on the main control panel in the kitchen. I called Newell.....they said it was no longer manufactured but that PMI was the circuit board manufacturer. I went on line and cannot find information related to PMI thermometer circuit boards.

Does any one know where I can find this circuit board?
Or alternatives to obtain the referenced temps and have the indicator installed in the panel?

The last trip in my coach was in March and since then, it has been stored hooked up with shore power. So, this weekend I start getting the coach ready for travel at the end of the year, and 3 of the 6 house batteries positive posts are dissolved. When I opened the bay, the 3 posts had that "corroded" build up. When I started cleaning, the positive cables are still attached to each other, but no post. 

Obviously, I now need new batteries, but what happened?

Gurus,

I have some general questions that I should know the answers to, but I don't ...

4 speed Allison transmission. Do I check fluid level  as I would in a car? Warm transmission, engine running, trans in neutral?

Time to add some coolant, Its 2 " below the sight glass when cold. Has a bright  green color to it. Was last serviced by the Detroit Diesel dealer in Sioux Falls, S.D.
Service receipt does not say what coolant was used. What should I add? Might  be 2 gallons low. No evidence of a leak. Appears to have a new radiator cap.

Coach has 11R 24.5  tires. Have been running 100 lbs front, 95 rear. Is this ok?

I made quite a mess trying to add oil to the crankcase from the oil reservoir. This was the first oil needed in 2600 miles. I had opened the air  pressure inlet, and opened the air " breather" thinking it was the outlet to to engine. I had not discovered the trigger valve releasing the oil to the engine. Needles to say, I made oil soup and blew about 2 quarts of it on me and the engine compartment. I'm sure I will not forget how to add oil in the future. How do you handle engine bay housekeeping? So far it's been paper towels and citrus based cleaner, but the results  not as clean as I would like it. I have a pressure washer but am hesitant to use it in the engine compartment

Can the air dryers on Newell's be removed without letting the air out of the system or can they be replaced simply by unscrewing the canister and putting on the new one?  They are a little difficult to get to, but believe that i can get loose and off using a big filter wrench.

Thanks.
