Hi guys, 

Need a little guidance. 

The air regulator in the curb side aquahot bay seems to have gone bad, it has a body leak. Not a problem I have a new regulator. 

My questions:
1) I have not figured out what this regulator is for, the slides are working properly? Any ideas?
2) To keep me from creating my next project, please let me know what psi it should be set at, I don't want to blow something out. 

A couple of pics below. 

I appreciate the help. 

We held off on our first shake down trip, waiting for those diesel prices to crash. We depart second week of May to Key West, a few stops (New Orleans, Mexico Beach, Tampa, Orlando on the way back).  

Thanks!!!!

Had a little scare on our way to Richmond, VA. Taking I81 which is hilly as heck. Just outside Roanoke, the Allison keypad starts dinging and then goes blank, except for two vertical division signs. None of the buttons work. Automatically assumed in my panic that it was stuck in 6th.  I was afraid it would bog down exiting 81.   So, I did what any other 1999 Newell owner would do….call Richard of course. He corrected my description and told me those were called Cateyes and I was screwed. Ok not exactly. He agreed with my decision to not stop until I found a safe spot. Our planned campground was out in Buchanon (back in site). I decided to press on to Richmond. I knew worst case there’s a decent Allison service place. Not stopping brought about an interesting issue to a 60 plus guy that loves coffee and needed a bathroom. I sacrificed a couple bicycle water bottles as my wife relayed them to the bathroom. I decided to do a trial run coming to a stop in a rest stop. Luckily it downshifted and went back up again leaving the parking lot. Arrived at the Allison dealer after closing. Parked, shut it off and began diagnosing based on Richard’s suggestion. Spot on as usual. I plugged and reseated the plug on the back of the pad and on the TCM. started the coach and the pad came back to life. I looked up how to check codes with the pad (Richard) and it threw a 2312:  shift selector or cable fault to TCM, Cateyes may display. Since we had a long way to go on this trip, I decided to have their tech do a diagnostic the next morning. They basically found exactly what Richard said in between telling me none of these parts (keypad, TCM) were in stock. Too old. We cleared the code and I thanked them by scratching out a $450 check, that hurt. So I left still afraid it will happen again and looking up where I can send the computer and keypad for rebuild just in case. I’ve attached their diagnostic sheet if that helps. 50 miles so far and it’s working fine!  Fingers crossed. 
   

This is not my idea but when I saw it, I knew immediately that is was very clever. The trick is to ise a fuel
Priming bulb like you see on outboard motors. Plumb up
The bulb so you can pipe it just upstream from the fuel filter. Take it out once you get the system primed

    Well I did get a newell after years of wanting one. Finnaly found one that was cared for all of its life. Have every oil change every part and everywere it went in its long life. it looks like the picture the factory sent me from when it was delevered. 
Being a mr fix it. I went over every nook and cranny. I have had 2 other Class A but never found anything built like this.  Has thing like Halon fire suppression system in genrator space.  And more things that I have never seen. All great.

Another person asked what should you expect to spend (in addion to the purchase).
Here are some of the things i did:
Changed all oils axel differental engine  (about $3000)
new tires $7000 8 of them (they just hit 5 years)
I was lucky the air bags were changed by the last owner
Had one engine code that was a small thing
Wiper blades and back up camera

I had to replace the air compresser for the house (i was lucky i found it on facrbook marketplace)

it was about what I expected to spend on a well maintained rig.

i am looking foward to sending 2 months this year going west.

If I can help anyone from my learning process contact me

So I had issues with the heater core at the front of the coach about a month ago.  I closed off the two valves that seemed to stop the flow of antifreeze to the front of the coach (the two valves closest to the front of the coach - BACK of the engine since it is mounted backwards as opposed to a truck…???).  
I drained, filled with water, drained, filled with water and ran the engine until the thermostat kicked in and drained the water then put in Final Charge RED Extended Life Antifreeze.  
I had an unexpected result today.  We traveled about 5 hours to Mississippi and settled into an RV park.  Went to take a shower and no hot water. Since I had turned off the heat loop to the front of the coach maybe this affected the engine heat to the Aquahot…??? 
So this started me thinking, which always gets me in trouble but NOT hot water this time, that I could just crank up the diesel or 240-volt electric AH and we could take nice hot showers as always. I went outside and everything looked fine BUT there was no juice in the AH tank that I could feel with my finger. The overflow jug was a little over the COLD mark.  
I didn’t want to start the AH with no juice but what was really ODD was that the juice in the overflow was now RED not the old green stuff that I had in it… I’m confused as to whether I should top off the tank with the old green or use the new hotness RED… what do you guys think and how on earth is this system connected to the engine now? Did I turn off the wrong valves??? 
The engine/radiator ran perfectly (after burping) and it even sucked antifreeze out of the overflow bottle which I’ve never noticed it doing before… 
BTW, the 12 to 24-volt conversion on the SCS air conditioners is working GREAT!  Ran for 3 hours on the genset in 80f and performed great front and rear! It’s almost cold in here now! Thanks to Gino/Jeff, Tom and others for their help! Now I have to get the heater system working with it and I’m golden (or time to sell!) …

 help how do I make sure my 2007 newell is in park please help me it's my elderly father's and he can't drive anymore

Has anyone had any luck replacing their oil pan with the military type? Mine is rusted out and the best condition/price seems to be the military version but it has a different shape and I think you'd have to modify the oil pickup maybe.

my 120 V air compressors won’t start automatically. I have checked all of the fuses and breakers and the GFI‘s that I could find. They will manually turn on by switching switch number one on the main Newell board. Any ideas where else I can look for an issue

Hi guys - our coach is in a shop in Myrtle Beach, the techs are trying to find some rear lower control arm bushings, apparently Newell does not have the parts any longer. They have been searching for two months now. 

Does anyone on the boards know of another possible supplier? 

Thanks for any suggestions,

Dave

I am now the proud owner of coach 738, a 2005. 
this site is awesome ans a wealth of help. 
I picked it up last week in FL and drove it to MI. We had a couple of thigs happen on the way that I am in the proccess of taking care of, but that is to be expected.

Both the wipers stopped working on the way when we had some huge wind gust that lifted then about 4 inches off the windshield and stopped them from moving. If anyone has info on checking and or replacing the wiper motors, that would be helpfull.  

A waterline under or behind the fridge started leaking. I will take the drawers out, the bottom panel off and see if I can find the leak. 

One of the former owners took out the thomas air compressors and replaced it with one cheap Campbell Hausfield. He has the pressure regulater on the compressor at 40PSI and I am not it sure what that should be set at. 

Thanks much guys.
