Now it explains why Dodge 1st Gens and early 2nd Gens did awesome for MPG and then as the years rolled on they got worse. Can't have a good MPG vehicle in US.

900 The CCD data bus is not operational. 920 The cluster is not receiving a vehicle speed message from the PCM. 921 The cluster is not receiving a distance pulse message from the PCM. 940 The cluster is not receiving an airbag lamp-on message from the ACM. 950 The cluster is not receiving an ABS lamp-on message from the CAB. 999 An error has been discovered. Sounds like you got a NO BUS message and lost CCD Network communication with the console. http://articles.mopar1973man.com/general-cummins/34-engine-system/81-ccd-data-bus

Check the blue wire to the alternator it should be +12V and the green wire should be a variable ground. Now if you unhook the green wire and add a ground from the alternator to ground itself the alternator should be in full runaway overcharging. Did you check the alternator fuse?

He's in Canada... I do have the limits for the US... http://www.towingworld.com/articles/TowingLaws.htm

Public scale and find out huh... I scale out at 7,300# (3311.224 Kg) This should help. http://forum.mopar1973man.com/attachment.php?attachmentid=1546&d=1301768538

As a last resort you could visit this site and ask them... http://www.rvforum.net/SMF_forum/index.php As for the flame sensor (flame rectification) is what is suppose to tell the control board to hold the propane going. Here is the manufacture... Maybe something might help... http://www.thetford.com/HOME/PRODUCTS/NorcoldIncRefrigerators/N641/tabid/540/Default.aspx A quick search turns up a bunch... https://www.google.com/search?q=norcold+refrigerator+flame+problems&ie=utf-8&oe=utf-8&client=ubuntu&channel=fs

I assume you talking engine oil from the vacuum pump area... http://www.fixinrams.com/id14.html

WOT = Wide Open Throttle (at highway speed)I was just wondering if the lift pump is running low pressure under load causing other issues...

Like if I wanted to I could pack up my laptop, 300w inverter into my pickup and fire up the laptop hunting for a WiFi signal in a town like McCall, ID. Park my truck on the street or parking lot and tap someone's WiFi. Now being a honest person I would just surf my web site and go on about my way. But if your criminal with a stolen credit card, looking to do illegal hacking, etc well this is the perfect place to do it. Because you now got Internet access with a non traceable IP address and nobody knows where your at. It just that the provider of Internet signal takes the fall for the illegal actions because there IP from there wireless hub is logged on what ever server. Like I know my wireless hub has about 500-750 foot range which basically over to the neighbors place too. Once again if I left my WiFi router up and running (broadcasting) even with WEP security it not truly secure as I pointed out. All I'm doing is alerting you all to the fact if it transmitted over the air by radio waves I'm sure someone can/will listen in. If you want a more secure environment I would consider wired if you can. :wink:FYI: Wired networks can travel at speeds up up to 1 Gigabit. Where most wireless are 53 Megabit and lower depending on signal strength.

Like taking a manual tranny and leaving in high gear and rolling up to a stop sign and stopping with only the brake and not pushing the clutch in.

No kidding... That was a impressive thread...

Two thing I would do.1. Pull all 6 injectors and have them pop tested. Just to double check.2. Do a compression test to check the health of the cylinders.

But then there is a member here with 1.2 million miles on his 53 block. Check out CajFlynn... http://forum.mopar1973man.com/threads/3435-1-000-000-Miles-Yet?highlight=cajflynn

That's truly sad... :cry:Remember your still part of the family with or without a truck!

Ok typically in the DC power panel most all loads/fuses are 20 Amp so figure your max load is 60 Amps roughly in DC. That would put you with 10 AWG wire and you should be fine. But if it got that heavy battery cable on there I would use it but just clean up the ends the best as possible. I'm in the same boat to some degree. The 12V system in my RV is good that it power all the light and such fine but the life span of the batteries seem short but I know there bare over 1 year old and where replaced when I bought the trailer. My thing is I'm almost sure there is a voltage loss between the battery and panel which is creating my issues. Because as you drop loads on it the voltage falls quickly like using the slide it will pull the batteries down in the 10 volt range but when the load is gone the voltage rises back up. Kind of like a plumbing restriction (fuel pressure falls hard under load but pop back up when the load is gone).

Time to call in your warranty...

The Bus is simply just two wires... Take notice of the 2 twisted wires that is the CCD Network bus. [*] Bus Shorted to Battery - Did either wire short to +12 volts? [*] Bus Shorted to 5 Volts - Did either wire short to a sensor wire +5 volts? [*] Bus Shorted to Ground - Did either wire short to ground? [*] Bus (+) Shorted to Bus (–) - Are the 2 wires shorted together? [*] Bus (–) and Bus (+) Open - Are the 2 wire broken loose somewhere? [*] Bus (+) Open - Is the Bus + lead broken loose? [*] Bus (–) Open - Is the Bus - lead broken loose? [*] No Bus Bias - Is the proper voltage present on the Bus wires? (2.51 Volts and 2.49 Volts) [*] Bus Bias Level Too High - Is the voltage too high? [*] Bus Bias Level Too Low - Is the voltage too low? [*] No Bus Termination [*] Not Receiving Bus Messages Correctly What CCD Network does is just like the ethernet cable on your computer for internet. One wire has all the positive pulses and the other wire has all the negative pulses. When the computer see the 2 matching pulse going positive and negative it good information. But when the mirror pulse disappears, or got a spike, etc then the data is bad or corrupt. So after so many tries the computer(s) give up and throw the NO BUS message.

Here is the reasons for No Bus... [h=2]Bus Failure[/h] The CCD data bus can be monitored using the DRBIII scan tool. However, it is possible for the data bus to pass all tests since the voltage parameters will be in “range“ and false signals are being sent. There are essentially 12 “hard failures“ that can occur with the CCD data bus: [*] Bus Shorted to Battery [*] Bus Shorted to 5 Volts [*] Bus Shorted to Ground [*] Bus (+) Shorted to Bus (–) [*] Bus (–) and Bus (+) Open [*] Bus (+) Open [*] Bus (–) Open [*] No Bus Bias [*] Bus Bias Level Too High [*] Bus Bias Level Too Low [*] No Bus Termination [*] Not Receiving Bus Messages Correctly

Would hurt to check it...

So I can safely assume its a 5.9L Cummins 6 Cylinder (ISB)?If so I would start out with a few basic things like fuel pressure and error codes. Fuel pressure needs be checked at idle and WOT at highway speeds. Both of these things will tell a story about the fuel system and what the problem might be.

P1688 and P1689 is a VP44 death codes more so the P1688.The P1602 I'm not sure of some point to SKIM error in the PCM, some point to cruise control error, etc...

I just wanted to alert everyone to the wireless limitations. At least people in my area have the idea that wireless is secure and you don't have worry about it. :duh:Like my wireless is harden up quite a bit. I'm using WEP signal (encrptyed), then I'm NOT broadcasting my SSID, then on top of that I'm firewalled for only certain MAC address devices. Basically my wireless doesn't exist to the public but only for my laptop can see it. :smart:Funny my neighbor left his wide open and I can hop on and see all his network... (Yes. I already warned him too!)

AirDog quick connections are known to leak air bubbles on the suction line. One of my pet peeves with AirDog systems.

3.7 L engine is unusual engine size. Could you give a bit more information on the build of engine you have or maybe a picture of it?But the rough idle could be a air problem where the fuel system is draining back and creating a air bubble. As you rev it up its capable of taking the air and pumping it through but idling its just start to stumble.Being I really don't have any specs for a 3.7L I'm going to have to guess at it a bit.
