pmd solution

Thanks for the info. When having all the troubles did you charge the batteries each time, or jump the vehicle a few times with the charger or another truck?

1st set died of old age. Second set I charged on slow or trickle each time. Factory warranty replaced them.
Third set were always charged on trickle save for the IP replacement. That was an A/C shop cart fast charge. That set died within the original warranty for the 1st set but I could only get 50% value against 4th set. Optimas this time.
Only jump I've received was for the first set with SSD PMD still on the intake. Over three years ago.

Personally I don't think we can narrow it down to a specific cause, it's like the straw that broke the camels back. Many different things added up finally break it. Not saying that a voltage spike wouldn't fry one however.

Thanks, that helps, perhaps the limited amount of "jumping" may have saved your PMD, and as well, the PMD would be well grounded on the intake if it was metal to metal connection. The rapid charge wouldnt hurt any vehicle electronics, just the batts potentially

Oh and lets not forget about that Filter Harness http://www.thetruckstop.us/forum/album.php?albumid=666

I had a gray PMD one just die after 13 months using NO filter.... Anybody else not using one thats experienced a failure, or using Heaths PMD?

That filter is on the Optical Sensor which does not share any power or signals with the PMD. I am thinking it would help to develop a filter on the PMD harness though. maybe I will draw something up and test in the future. My lack of PMD failures has left me content not even messing with it on the intake. I can at least test to make sure the filter does not affect operation.

Oh darn your right....I must have been having a brain fart....or subconsciously was thinking about wanting one for my PMD...

PMD still on IP since Dealer warranty in late 2007 or early 2008.....Without any issues.

But I'm always mindful of LP and contributing cooling effects, like idle after hard run, but thats mostly for turbo cool down......Or maybe I'm just lucky or got a good old/original black one.

Who knows?

Someone knock on wood please.

Yeah, and you live where it gets hot and cold. My truck lived in NJ for several years before the PO moved from there to CA, drove it cross country and had it in CA for a few years before selling it to me with the PMD on the IP. They may have been fortunately lucky to never even know that PMDs were prone to failure.

No PMD and DS4 on the military H1 hummers right?

No PMD and DS4 on the military H1 hummers right?

Pretty sure no military vehicles have them for EMP battle hardening reasons, a lot of military equipment is "dumbed down" for survival in nuke battle field scenario or if electronics can't be avoided those are "hardened" designs to try to better survive EMP

Nope.

Your missing your calling Leroy...Screw PMD Kits and Oil Cooler lines..How much can you really make anyway....:rof:

If you have a tried and true way to convert to a DB2 with retaining the Cruise and using a TCM that will work with OBD2...That is what you should be marketing...Put me donw for the first order. either that or get someone to do an in depth write ou of using the cruise setup off a 93 on a 96+.

This thread just reminded me that I wanted to look into the implications of converting and disabling the ECM for emissions purposes.

I wonder if someone like Bill H could tune the ecm to ignore all the nasty messages it will receive when the DS4 goes AWOL.

To me it seems that is a seller right there. You know what the guy who converts electronic Cat motors back to mech is making on those....17k for a conversion....

I can fix anything on a diesel as long as i requires wrenches but all this electronic stuff...Blahhhh

 

[Acesneights1]

I suppose the other issue would be finding a cruise setup out of a 93. it hard enough to find an IP. Also most of us have canned the vac pumps for a TM so that would require adding one although not sure if you could just plop a dist style one in. Might not clear the FFM.

Although there are H1s out there with PMDs, if you recall the guy came around looking for a lawsuit, not sure why he would have converted his to DS4s if they came with DB2s

 

[Turbine Doc]

Agreed;

I think eventually the civvy version Hummers had them to meet emissions, which was driving force for GM to put em on ours, before long all things Diesel regardless of application will have to be EFI. 2012 was the mandate on new locomotives @ GE when I was running our shop in Ga to be common rail, EFI was being phased in as they required o/h or failed the replacement engines had to be tier X compliant depending on type & age of locomotive.

Major project we had in 2 years I was running that shop we converted 400 MFI locomotives to some form of EFI sort of OBD-I to OBD-II, to common rail, I expect to probably see DEF setups on them as well, but I'm back in saddle as field engineer repairing gas turbines and have added steam turbines now to my "bag of tricks". Running a union especially a union railroad shop (I fully understand from whence phrase being "railroaded" comes from) was not a lot of fun and the 450 bi-weekly commute Ms to Ga and weeks away from home per month was not a good time either.

The tree hugger police is why you won't see this as a commercial offering Kenny with current occupant of 1600 Pa Ave and minions he hires to be Czars I'd half expect visits to all of us on forums that have done any mods at all that deviate from the OEM design like in many in EU where it is virtually impossible to modify vehicle legally.

As far as the tron stuff you can handle it, these aren't as sophisticated as one would think just invest a little time you'll git er done, you see what passes for a tech at GM stealerships these days they like the blind squirrel find the nut, and you aren't blind a little crazy squirrel maybe (like rest of us 6.5 diehards) but not blind

H1 is different than it's military couterpart. To my knowledge no Mil Spec 6.5s have PMDs. Someone correct me if I am wrong.

That's cause I'm a edumacated redneck too....
I think I just became anti PMD after working on and driving Jared(new member Godsmack)'s truck.
you hit the nail on the head though, States that do OBD2 tests will have issues.

 

[buddy]

I believe you are correct that only the civilian ones have the DS4.

 

[robzombie4551]

You're right kenny, no DS4 in the military. Like Tom said emp maybe, but definetly easier to [diagnose] fix in the field and more reliable.
