Basically you need to use an ohm meter. Not very hard to do. There are several you tube videos that explain it. You measure the ohms from the common terminal to the other two terminals, individually. then add them for total ohms; then measure ohms between the two terminals (not the common) and those ohms should be the same as the total from the other two readings. Kinda hard to explain but that is the best I can do. Bob L, 08 dynasty Frank: Mine came with zone 4, which as you said, is the bathroom and hallway. Zones1 is a/c and aqua hot; zone 2 is a/c only; zone 3 is a/c and aqua hot. Of course 1,2, and 3 also have heat pump Bob L, 08 dynasty

I have owned my motorhome since original purchase in 2008; 14 years and I never knew where the control box for zone 4 of teh aqua hot was located. Thanks Frank. Guess I am lucky that I never had a problem with it otherwise I would have probably torn the bus upside down looking for it. Bob L 08 dynasty

Thanks Frank: Where might that "hidden" control board that operates zone 4 be located??? Bob L, 08 dynasty diamond iv

Thanks everyone for your help; but a miracle happened and I found the correct conversion board that will allow my new a/c to work with the 5 button CC. I was told by Dometic that they were on back order for over a year with little hope for the future. However Camping World in Pittsburgh had one. Thanks again and saved by the bell. The dw will be happy to get that a/c going again. Bob L, 08 dynasty

Thanks Vito; I kinda figured the same thing but was thinking I could make the switch. I am going to check with Micr Air but I think my best bet is toput in a separate thermostat for the new unit and be done with it. Bob L.

Ok, here is my problem. I am replacing my middle A/C on my 08 dynasty. I have the 5 button Control Center (CC). I am replacing a 15000 btu with the newer 15000 btu Penguin II. My old a/c finally gave out; it was the original. The problem is Dometic tells me that the conversion kit needed to make the new unit work with the 5 button is on back order for over a year with no end in sight. Two questions: The board in my old unit is still good; can I place it in the new unit and have the 5 button work??? If not, tell me what I need to do to get it working. (I can't replace the 5 button because my other two units are newer and when they were put in the conversion boards were readily accessible so I am kinda stuck) Help would be appreciated cause it is hot. The problem with the old one is compressor, not the board. Or does anyone have the conversion kit they want to sell. Thanks, Bob L, 08 dynasty

Yes; and I can't get he daily digest e mailed anymore. This problem started about a month ago. Don't know what is going on. Scotty was going to look into it for me.

Thanks; I have the 16 lb cap on my 08 Dynasty; never had a problem but good info. bob L

Chris: Not being a physics wiz kid, higher pressure cap causes engine to run cooler??? Correct or not?? Bob L

I assume this thread is about the Load Shedding Device that went bad. I have an 08 dynasty and although mine did not "burn up" it quit working. I did what Frank suggested and just put in a junction box, then put a small sign on the washer:''turn off A/C before using washer". Problem solved; and if by accident both are turned on at same time, the breaker trips. After replacing that box twice, I put in the junction box. Bob L, 08 dynasty

I have an 08 dynasty. The windshield wiper motor died on me today in a thunderstorm. Fortunately I was able to get off the hwy until it stopped raining. Does anyone kknow the make, model of the motor. Doesn't look to be a big job to replace it. And yes, I checked the fuse. I am fairly certain it is the motor as it just slowed down until it quit. Ran for about 10 minutes then slowed down and hardly moved, then quit altogether. Thanks Bob L

Had a Cummin's tech look at it and after several different tests (resistance, etc) we concluded that actuator was shot. Took it off and sure enough correct diagnosis. Cummins has a new one coming in tomorrow. The turbo looked fine; the lever moved freely with no problem. After we put it on and calibrate will post the final $$$. I did have a mobile tech come out to my bus barn who really knows what he is doing. Bob L, 08 dynasty

Jim: That is a possibility Where are the resistors located on your coach; I have an 08 dynasty Bob L Thanks Jim: Found them. In same place as yours Thanks, Bob L

This is the ISL; 07 engine and never has done this before. Do not lose any boost with the red light on. I started it this morning and it ran for about 10 minutes then the red light came on. Tried to call Cummins in New Orleans but all I got was answer machine. Left a message but have not heard back yet. Oh and I have 75,000 miles on the coach. It has been a great coach with no problems until now and I wish I knew how big of a problem this is cause I ran it on the hwy yesterday up to 75mph with no problem.

Went to take off for the fourth of July and got about 1 block and red stop engine light came on. Turned around and went back to the bus barn. Error code 2636 shows up which says Abnormal Update Rate to the Actuator---the data cable not sending to the ECM. So check a few things then started up again--no light. So took it out on hwy and light came on. WEnt about a mile and light went out; ran about 10 miles and still no light. So I tdurned around and went back to the bus barn. Had lunch then tdried it again. Light came back on; ran for about 10 minutes in place and light went out. Tried again this morning and no light; but it came on after about 10 minutes then would blink off and on every so often. I checked for loose connections from the actuator to the ECM but nada. Not sure what is going on; several suggestions in the Cummins manual but have not gotten any further into it. It appears that it is an intermittent thing--not sure if it is the 12V to the actuator or the data link. Anybody have suggestions?? Bob L, 08 dynasty. P. S. bus has run perfect until this happened. It only sat for about 2 weeks before I tried to take off for the 4th.

Been following this discussion; was wondering if anyone had any problem getting the air out of the system. My ISL takes a lot of coolant and was just curious as to how long you keep running the engine to get the air out and should you watch for the "burb" at the coolant tank. Bob L, 08 dynsty

Sometimes I turn them off but many times I will forget. Since I have very few air leaks (about 10 lbs every four or five days) I am just going to pull the fuse and forget about it. Bob L, 08 dynasty

From everything I read, I come to the conclusion that there is constant 12 volt power to the aux compressor at all times--regardless of whether the Valid system is turned on or off. So if in storage, the pump will come on if pressure gets below 90 psi, even though everything is turned off. I don't like that-- so I will keep the fuse pulled. Bob L. 08 dynasty

l have an 08 dynasty with the Valid (Power Gear) air levelling system. My question is this: with the system turned off should there still be power to the aux compressor. I always thought that with the system turned OFF after I level, the aux compressor would not come on. However, it does--while everything is turned off. It is not a problem with the pressure switch as that works fine; I pulled the fuse, but when I replace the fuse the compressor comes on.(with the system off) I don't think that is supposed to happen or am I wrong. Now if the system is turned ON then the compressor is energized although it may not come on because the tank pressure is ok. Thanks if anyone can answer this for me. Bob L, 08 dynasty

Richard, the one in the generator compartment goes directly to the front tank; at least on my dynasty. The air from the tow truck does not go thru the air dryer on the motorhome. when you need the tow truck for air you have to hope it goes thru a dryer on the truck first.

For years I have been faithfully using Mop n Glow on my roof probably every six months. However my roof is now starting to "chaulk up" and when it rains I get the white streaks down the sides. I am looking for suggestions for coating (or painting) the roof to prevent this. ANyone have the same problem and cured it?? Thanks for any info that is available. Bob L, 08 dynasty

Thanks. I have the BO Aventa LX. 10000lbs which is different from the one pictured

I looked at the picture and am still trying to figure out where the failure occurred. Was it where the tow bar is attached to the tow vehicle or where the bar is attached to the swivel (ball) at the coach end.

Frank: thanks so much for your efforts; I just downloaded the files and no problem. The info is tremendous. Thanks again. Bob L, 08 dynsty

Bill was a good man always willing to help. He programed an extra multiplex CPU for me. He will be missed. Our prayers for him and his family. Bob L 08 dynasty
