How do I correct uneven tire wear?
I've always looked at it as tires are flexible, and when you are toed out, the insides of the tires are what is going to be rubbing the most as the rubber flexes. The tires will pull the inside edge under to make the inside of the tires rub on the road more. As for what effect the camber/caster has on the tires, I am not sure. Also, I was just kidding about your 12v above fyi. ;)

ISX, A few drag racers I've been around would run some chalk (like from a chalkline) across their tires, then roll it forward on clean black pavement and see where the chalk sticks. Some of the others would chirp their tires, and see if the tire imprint was square. Even with the 12V you should be able to spin the tires with the NV4500 . They would adjust their pressures accordingly.

Anybody have a Deuce and a Half? M35A2 / M35A3...
Very cool Mike. Thanks. They look like really solid trucks, and might be fun if I can find a cheap one.

Anybody have a Deuce and a Half? M35A2 / M35A3...
I don't know where to start really. I am just starting to learn about them. I like the concept of the multi fuel LDT diesels, but I haven't really worked on them. Are they decent engines? I have a lot of old oil that I can filter and run in an LDT :)I also like the CAT 3116 diesels and allison automatics in the newer deuces, but I am not sure I can afford an M35A3. If I get one its probably going to be a cheap surplus truck, and hopefully I can work through whatever issues it has without costing an arm or leg. What are some of the common things that you have to check up on with your adopted fleet? From what I read they are pretty simple, but some of the bearings & seals can be a pain to replace, but all are available and the manuals are as simple as a coloring book. Thanks Mike!

Yes, I am crazy. But they look so fun! And with scrap prices, i am pretty sure that I could part out/scrap the thing if something major breaks and nearly break even. If I can find one with a winch for cheap enough... It might just come home.I am not crazy enough to get a 5 ton with the 800+ CI cummins in it. If I had a CDL, perhaps, but I think the 5 ton might be a bit too big. If anybody here has a deuce, I have some questions.

4th ECM...PLEASE HELP
I've had a similar problem. An ECM and many edge juice modules. I finally got it out of edge exactly what was burning out, the noise filter on the juice. They said that this is an occasional problem with these trucks, and in the past they have put more robust noise filters on their modules to combat the issue. I have acquired a flukemeter (cheapie meters won't read fast enough) and I have found that I have a weird voltage spike in my power system somewhere... I have replaced the alternator, and replaced or checked just about everything power supply related aside from the PCM. I have also had it into Dodge to be checked out and they can't find anything out of the ordinary. I haven't been able to find the time to check it with the alternator disconnected, but I am wondering if I have a solenoid (relay) with a bad diode could be backfeeding some noise into the system somewhere. I have been looking (as ISX has been) for a good solid state heavy duty voltage regulator to avoid replacing the expensive PCM, but I haven't found one yet.

Fuel pressure diff at altitude
I have seen a lower fuel pressure as welll, however, I have also found that stopping near the continental divide and filling up really doesn't have any influence on fuel boost pressure. I saw about 1psi drop / 1000 ft of elevation change. I never found any relationship between temperature to fuel pressure. The only rationalization that I could come up with was that the fuel pressure gauge was calibrated for absolute pressure, not a relative gauge pressure. I am not sure if that is true, but it was all I could come up with.

All, anybody know why I am seeing 29VAC at 13.9VDC on an alternator?
A great guy from ARFCOM offered to loan me his Fluke 87 meter, great guy. I am seeing a spike in VAC every 15-30 seconds or so of several hundred millivolts when the engine is running. Base VAC is 13 millivolts. I am going to do some further investigation when I get back from vacation... and once it stops raining / snowing. :hyper:I am going to troubleshoot the alternator and voltage regulator, by disconnecting the feed of the alternator and looking for the spike. If this eliminates the issue, I am going to look for a new PCM or a solid state external voltage regulator. If the regulator and alternator test have no influence on the voltage spike when running just on batteries, then i probably will start looking at individual relays and systems again. I wonder if the heater grid has a big relay on it or what... I will need to spend some more time with the wiring diagrams and make sure the grounds are good as well. A high power relay could make some noise, and I am hoping that with this excellent high sample rate meter, I can figure it out! If anybody has any suggestions while I am away, please post away!

If you see some C-130s with the Colorado Rockies logo on it, wave for me. USAF Reserve from Colorado Springs, they are some good guys.

Very weird problem
This thread is relevant to my interests. I wanted email updates if anybody posted anything new. I am burning out noise filters in my edge juice modules, and can't figure out why. So, I am interested if you update anything.

It doesn't do frequency unfortunately.

Yeah, flukes are nice. Someday I will own one. At any rate. I just tried putting the edge juice w cts on again. It didn't work and did the same thing it did last time before I sent it back and Edge Products "Fixed" it. I checked every ground, I cleaned every connection with contact cleaner. I checked the resistance of every fuse. I checked to see if I was getting 12V at the right places. I even tried only plugging in the minimum of wiring (no turbo timer or temp probes). Nothing would get the CTS to connect to the juice. It was seeing the OBDII output, but not the Juice. I wish I had a 12 valve ISX. lol. At this point, I am convinced it isn't my truck. I have a NEW ECM. New alternator. And every bit of wiring on the truck has been meg'ed and checked out for any stray voltage.

Tried an analog tester as well. I really need to find somebody with a fluke tester... Unfortunately the Flukes we use at work are on the other side of the state and probably will be for about a month or so. I am going to replace the regulator with an old school 1st gen regulator and see what happens, if that doesn't work I am contemplating buying an oscilloscope, and actually getting a look at the waveforms coming out of the damn thing! I am at my wits end here with this. --- Update to the previous post... OK. I figured it out. As I sat in the NAPA parking lot it occurred to me to try testing the VAC while the ignition is on and the engine is off. (as I was using test leads through the power outlet to test while driving) It showed 26.5V in ac, and 12.5V in dc. INTERESTING! Same results when testing from the batteries and when the alternator feed is disconnected and the enigne is running. So instead of putting an external voltage regulator in, I went and found an 01 and 97 Cummins pickup at a dealer to test the voltage. Both trucks, show EXACTLY the same "AC" voltage on my meter. I am chalking it all up to instrumentation at this point. There is currently no evidence to show that my trucks charging or electrical system has any issues. It appears that I have been chasing my tail with a miscalibrated cheapie multimeter showing 18V dc, and then instrumentation on a mid range $100 multimeter showing ac that doesn't exist, or even if it does exist its normal! Off to put the Edge CTS back on... hopefully it works this time. Hopefully, somebody else learned something from this or will if the search for "ac voltage" or something later. At least I have a spare alternator now!

Backstory: My original 211K alternator was outputting 35-45VAC and normal DC voltage. With some input from Mopar1973Man, all I could gather was that a diode in the rectifier in the alternator was really acting up, but the regulator was keeping the DC voltage in check allowing a AC waveform through. Speed up today: I bought a new premium NAPA alternator and replaced it. The voltmeter is reading a beautiful 13.9VDC, and 25.8VAC. ETA: The standards I have read online for an alternator is .09VAC MAXIMUM, and that if you are reading over that, your diodes are screwed up. I am so confused by this. Anybody have any ideas?

Picked up a "New" (Used) computer... hoping this was a good deal.
Some of the old dells are rugged. I have had a couple for work, and the seem to last forever. The only downside is a limited number of USB ports on some of the old models. However, if you aren't like me and running a verizon aircard, portable hard drive, mouse, power for a phone, and a toaster from your usb ports, you should be fine.

Russ, I have several Win 7 laptops, and I can walk you through the process if you can't figure it out. Another suggestion I have is that if you get a monitor, you can setup your laptop screen as the primary screen and then use the monitor as a second (and hopefully bigger) monitor. I have this setup at my office and like it a lot. Win 7 is a little tricky in setting that up for an intuitive XP user (i struggled with the transition) but I am very happy with 7 now. If you set it up this way with dual monitors, you wouldn't need to worry about making it run with the lid closed. Let me know if you need help.

Worthless PCM
Alrighty then! Thats impressive ISX. I hate electronics. Re wiring 1970s mopars sucks enough, but rewiring a modern truck would probably make my head explode.

Hood Insulation
The local Napa near me has a good supply of clips that are similar to the originals, although finding some originals might be better. But that wouldn't solve the issue if the insulation is deteriorating. In that case, if you really want to keep it, you might be able to make some long plastic ribs to run clips through to help keep it in place. I took mine out years ago and haven't missed it really... With the hot turbo and exhaust manifold I felt it was more of a fire hazard than anything else.

Check this out...
That was my first instinct as well... But that really might cause more trouble than its worth. Many towns are now writing big tickets $350 for a "excessive amount of smoke." When I was younger... I may have learned that the drivers side window of a 97 F-350 lined up perfectly with the drivers side window of the local gangbangers rolling boom box and could outrun their too fast too furious civic... That, and if she had a video camera, she could make a bunch of headache for us.

Any specs on the filtration level of the different filters? Where are you finding your info if you don't mind me asking...?

Check this out...
Liberal land monster, check. Drives a Prius that is worse for the environment than the Duramax, check. No respect for any view other than her own, check. Tells people to be considerate, check. Heratic? Check. Needs to get a life? Check. I get flipped off on a semi regular basis and get road rage on a regular basis for just working in the oil field. I can't stand these people. Makes me wonder about America, but then I run into some really great people who work hard, love their family, have good character, have integrity, and it really makes me proud... Sadly, I am running into the latter less and less often... And very few of the latter are young people.
