Found the problem in the new cable installed from front a/c to thermostat. you CANNOT use phone cable, unless you change the ends on this cable to match the same color as the rj11 cable. You will need to get phone cable and look at the end to understand. Boy I learned something this go round.......thanks for all the information guys, again I love this forum and the people in it.........and just a small piece of advice, when it starts to get on your nerves, just walk away, have a great day....vince

Pulled the cover off all three units and checked each 3amp fuse all checked good 13.7 to be exact. I all so checked it with gen running same thing. No fans no nothing, not even a back ground light in the thermostat. Yes salesman switch bit me a long time ago now even if I have any thing go wrong I check that switch.FIRST,lol.......I'm going to leave it alone for a couple of days and go back and check every thing again. It's right there and I'm over looking something. OBVIOUSLY 🤔

Loaded up to take grand kids to the beach and no a/c. Thermostat won't even light up. Removed the thermostat, 4 wire rj11 cable, no power. 2009 Cheetah Safari, it has 3 roof units. Domestic, the thermostat is a 5 button duo-therm comfort control. I replaced the control box which is located in the center unit. Still no power. I checked all three units for power all had 123 volts.. the front a/c has 2 rj11 cables. One of the cables are marked and I see the same marks on the cable at the control box. The other cable goes in the ceiling without a mark. I think this is the thermostat cable if so, I have power on this end but not the thermostat end. I know what you are thinking, well replace the cable, BUT there's a small cable from the front unit and a adapter then the wire to the thermostat. I hooked up the thermostat where the adapter is and still nothing. I know I have power supply there. 13.7v to be exact. I also checked the ground at the same time. Any help would be appreciated. Font a/c # 630516.331j same # for rear unit. Center unit #630035.331. thermostat was also replaced for fun.#3109228.01 5 buttons. I set the dip switches from the old CCC. I also pushed the button to try reset but nothing will come up on screen..... Thanks again. Vincent Edwards

Thanks Carl I'm hoping falcon has a trick up his sleeve. I'm hoping that this problem will help others out there with this type of engine. Because this has been a headache. Thanks for time Carl. Vince

Yes I know what you are saying. We love the RV so I'm all ears. I want to do whatever you did to fix yours. I'm taking my grandkids to Disney in April and when I get back I hope I've got a plan to get to work with. Any help will be appreciated. I was just telling jleamont that the snap-on man I deal with and his friend that works at a cat shop will help me. So I just need a plan. There are some things that a cat shop want do, if you know what I mean. Like jleamont told me I'm looking for dependability not for power or fuel mileage, if it happens, great but I just want to drive my RV and enjoy the trip, not go "what's that" every other mile. Thanks so much for your time and help. If you want to email me please do. Vince

Thanks, I was hoping I read it right, you just help clear my mind. Went to a cat shop today and asked about the code that came up and he said the (vgt) actuator's are good for sticking, WOW....You know I'm on pins and needles the whole time I'm driving now, this is not fun anymore. I don't mean to be whinning but come on, when I build a transmission for my customers I'm held responsible. Cat needs to come to the plate and do what is right. I've worked hard my whole life, just like all of you guys and I don't need to put thousands of dollars in there stupid mistakes. Well I'm sorry for that outburst but I feel better...... Thanks again carl, at least I know I can count on you guys for help.

Thanks Mr. Falcon, I sent you a email, again I appreciate your help and all the help from the guys in this forum. I would love to fix it because the way I understand it now all makes and models are fighting the same problem. Now if I'm wrong about this and I don't fix this RV, I want to know who ain't having this problem so I can trade for one. My wife and I took our 2nd trip this weekend and the heist light came on after 6 hours on the road. Only when I stopped. No check engine light. I did a self diagnostic, code was spn 641 fmi 7. I told my wife were going to drive it and it's going to go or blow. It ran great and the ECM codes went away. I don't know it's man made. Stay tuned, my father's health is keeping me back and forth to Daytona FL, taking a trip in about 10 days I'll let you know what happens next. Thank everyone Vince

Mine is and I've had trouble ever since I've had it.

Bill, I'm not really sure how to do it. I'm hoping he will check back and see I'm trying to get in touch with him. Any help is greatly appreciated. Thanks again.

Bill and tbutler are right on they have been at this longer than me, but I will add one thing. Just bought our dream RV on Dec. 10th ,dec25, broke down in FL. Took it to a cat dealer, give them the warranty, no problem he said. When they called me 3 days later thay handed me a bill for 3506.17. Told me they couldn't get in touch with my warranty people. Must be on vacation, they said. Well guess what, just like tbutler said they found a way not to pay. So even if you do everything you are supposed to do, it's only as good as the shop doing the work.

Falcon6251,is there some way I can get in touch with you about the c9 cat?

Yes please, we love this RV. But I'm scared to go long distance because of this.

Thanks jleamont, that was some good reading back there. I would sure love to learn more about that auto start for the generator you were talking about. And yes obedb , I guess they think we're to lazy to plug in a cable . It would sure be one less thing to go bad.

Yes obedb, I couldn't imagine dealing with all these problems without the help from this forum and these guys. It has been the best tool in my tool box. I'm just hoping I'm not wearing out my welcome. So Brett don't get any big idea's and block me out. Thanks guys.....

Thanks jleamont, you sure have been a good friend the last 2 weeks and I hope I can repay the favor. I have another question about this problem. My wife and I noticed that on the intellitec load meter it's not showing the amps, on gen set or 50 amps. My other rv showed on gen set , but not on 50amps. So could this bad ats be the reason? Again thanks very much.

Thanks for the info, is this a good unit? I guess what I'm asking--is this the unit you would put in your RV. My first trip on it and I'm not having any luck with this RV. Just bought it from Camping World. As is, so I just want to put back the best I can. I would have thought they checked it out good before they sold it to us. I am a newbie and I really appreciate your help. I usually have my grandkids on board, but this trip (think God) we didn't. We just want it safe for them.

Wow, great information . This is what I've been saying, you can only get info like this from the guys on FMCA. Thanks ziggyh, you can believe I will do this.

Unbelievable week, after being broke down all week with an ARD head bad my wife and I made it to North Carolina.when I started the generator (Onan) no power. We were at a rest stop so I couldn't check the land power. I took my DVM and went to the ATS, removed the cover and oh my gosh what a smell. Wires burnt everywhere. It has a Iota engineering its-50R. Would you go back with this model or go with something else? Something better. This was our first trip. 1400.00 for 2 front tires, $3500.00 ARD head, now this.

Well to start with I really want to thank all the people that helped me out with this problem on my first break down. Especially jleamont, he talked me into doing the right thing. Picked up my RV this afternoon from Ring Power Cat in Daytona. Those guys worked hard to get us back on the road so we wouldn't have to rent a vehicle to get home with. The ARD head was bad. $3506.17 parts & labor. Unbelievable. So if you have one on your RV get ready. This RV has 29564 miles. What a sorry design. Cat should be ashamed. That's all I've got to say about this. If you need any help just ask these guys on FMCA-- they are awesome. Thanks again guys have a happy new year! Ps...if your going to break down, Daytona is the place to do it....it's been in the 80' all week. ?

Well I live on Lake Gaston, North Carolina, about 1 mile from the Virginia line. My 2001 isb 300 5.9 Cummins was great. I installed a eng.speed sensor and lift pump which I replaced my self. I went to Cummins sales and service in Kelley NC to get my parts and when I said something about a program, absolutely not he said. So I left it at that. But if you think it will help I will sure look into it. I don't mean to sound ugly on some of my post, it's just our first trip with our dream rv.we have work hard to get to this point. I'm an ASE tech. I've run the family business for 40 years.I'm not use to other people working on my RV. But I don't know nothing about this new system. My first break down and it's just got me rattled. Thanks to all you guys it's going to be alright and I hope I can help ya'll some day. I will be calling back.

Well what a long day this has been, jleamont, took your advice and took it back to Ring Power (Cat). Alex (shop foreman) put it on the computer and manually regen the ARD head and it ignited. Hurry! BUT it didn't last long only 85%. When it went to relight, nothing. He tried 3 times. So installing an ARD head. Again if you have a 2007 to 2010 RV an ARD head is in your future. Stay tuned, I'll let you know what the price and time frame is. Thanks again guys for your help.

Thanks every one for your help, my wife and I went to Daytona this morning and talked with the shop foreman at ring power (Cat) great guy to talk to. Jleamont, if I didn't know better I would think you were sitting right next to me. He said about word for word. I did try the spark plug BUT no go. After I installed the plug, we went up the road 10 and back. 20 mile round trip and it runs great. If it weren't for the lights on in the dash, you wouldn't even know. Would you try to drive it back home 700 miles to my mechanics. Or leave it here in Daytona? Honestly I want to take it back where I bought it.........well I'm going to be nice.. thanks again to all of you trying to help, I've always been able to get good information from you guys. Have a merry Christmas and a great new year.

Thanks again, I've been looking all over this RV and just don't see a def. tank. I've been all through the owners manual and no talk of a def. tank. After I install this spark plug (in my diesel, I know, I know) how do I reset the code light? Or will it do it automatically if it's fixed? PS I traded my Cummins with 100,000 miles and never a problem for a Cat with 28000 miles and didn't make it 700 miles. I'm not impressed at all.

Thanks Wolfe 10, Just talked to someone at a cat shop and he said I didn't put def fluid in a holding tank. What ! I don't see any place for that. I told him that and he said for me too get these codes I must be using def fluids. I'm really sick now.

Just bought a 2009 safari cheetah, on a 700 mile trip 696 of them were smooth, with no warning the step out light comes on. We stopped checked the steps, no problem. Got back on the road the check engine light came on. Before I could stop again a symbol pops up. Looked into owners manual it's the PDF light. I checked my temp,oil pressure and volts looked good so I drove to my dad's house. Cut the RV off, started it back up, lights still on. Took my j1939 scan tool from matco, got codes SPN 3474 fmi 31. Also SPN 3251. Now the next morning is 12-26-2016. It has a C9 cat, eng ser# c9s00936. Mileage 29000. Needless to say I'm sick, this is the very first trip. Any help would be appreciated.
