Not salty to me at all.  Isspro is late to the game on brining products to market.

 

Isspro had better certifications and is an OE gauge manufacturer for freightliner, marine and aeronautics, they have been ahead regarding quality for years.   Autometer did not have those certifications until a few years ago.

 

Auto meter is faster to market and far  better at marketing. Their price is quite inflated compared to the quality.  Heavy Marketing adds to consumer costs.

 

The EV3 will only be about $25 more than the EV2 and they will be a sealed gauge ( suitable for marine).  Their App is free and can be downloaded now.

 

We sell and stock both brands.

Alright here goes. I've wanted to do the W-T mod for a while but both Articles ( @W-T's and @Mopar1973Man's) even after reading them multiple times over a couple of years, I still couldn't wrap my head around the process. I think its a combo of my lack of knowledge and a bit of formatting of the articles themselves. It might just be the way my brain works/interprets things as well.

 

So I guess it comes down to I need a bit of clarification. And I don't know the best way to format this so please bear with me.

 

Things I understand fully about this mod:

- Its intent. Remove a problematic splice and poor ground run.

 

Things i mostly get:

- Where things from the factory are run. For the most part. (see below)

- The bundle of small gauge grounds that go into the timing cover. 

 

Things im not sure of:

- the alternator charge lead I think is part of the confusion i have with this mod. Where does it run and what does it hook up to?

- where all the new connections are. (I have some idea for this one. Just need confimation) 

- is the Small gauge ground bundle we make a replacement for the long cable? or do we have to add the other ground lead? (green wire on the timing cover for @W-T's article.)

             - looks to be a requirement.. "...absoute ground..." - W-T 

 

Just trying to finish wrapping my head around how this is laid out and accomplished. 

 

Thanks in Advance

I was overwhelmed trying to remember the entire process.  I kept my phone with me and did each thing one at a time. It was really simple to me doing it that way.

 

The alternator charge wire runs from alternator to drivers side battery over radiator. You will shorten it to run to passenger battery. This is where you can splice either a 150 Amp breaker or fuse if you want. The ground wires that you will cut to get the crummy oem connection out will be grounded to the timing cover. I used the extra charge wire to add a ground from same timing cover ground point to drivers battery. 

 

Don't forget to do the fuse mod in the blue wire to the pcm.

 

I may have explained it wrong, but if you go step by step,  it's not a bad or confusing job.

I think I'm more confused now that I've looked at the wires of my truck...

 

I think I need a crash course on alternator/electrical workings... So the charge lead comes off the alternator then goes into the PDC, through the 140A fuse then into the drivers battery. by moving the the charge lead to the passenger battery, we render the PDC fuse useless, needing to add a fuse to the new charge line. Am I understanding this correctly so far?

 

So what is powering the PDC? Seems like the red power cable from the battery does that.

 

The second grey connector that heads up to the firewall/cowl, I think @IBMobile has an article about this, where is that going/what is it connecting to? Trying to follow it in the wire diagrams on the site but it isnt immedeately clear.. Says that s126 is the PCM and data link grounds, but it says that it terminates at the firewall not the battery...

The splice is at the fire wall but terminates at the battery.

@dieselautopower, I did a stupid and jumped my truck and forgot to unhook the Quad. Is that a full death sentence for it? 

 

Guess what im asking is, should i send it in to have it looked at?

 

Possibly add that on top of my no Wait To Start and no CCD bus bus issues.. 

Call and talk with Quadzilla.  They may be able to repair it, if not they offer a new board as a separate item.

Strange I've jumped many vehicles and never unhooked the Quadzilla. No damage. 

 

No wait to start is a ECM death sentence, then the CCD codes are most likely because the ECM is not responding because the ECM never booted up which goes back to the lack of wait to start light.

Im assuming no ccd causes the no start condition as well.. 

 

CCD typically will not prevent starting...

 

Now the missing WAIT TO START will 100% of the time. Being that ECM never booted up and is not responding at all. The fact that CCD bus error means the PCM booted up and attempted to talk to the ECM and since the ECM is completely brain dead it will not repsond nor start being the is not software to turn on the fuel pump relay (power for the VP44) and then no information will be fed to the VP44 being the software is not booted. I would give @Auto Computer Specialist a call and have the ECM tested out and follow their suggestions on fixing.

Hoping to pull my ECU tonight an get it sent out in the morning. Cold, Rain, the Dark, and work put a real damper on working on My truck.. First decent day that i didn't have something already planned or was raining.

 

Finally got a hold of @Auto Computer Specialist, they told me that its the ECU. 

 

Need to work on the battery cables and W-T mod next as well..

Have to keep this up to date..

 

Haven't done much with the truck besides get new weights for it. My brother bought the concrete I was using and used it for redoing his mudroom.

 

Pulling season is starting soon, so I have to start taking care of some of the lingering wintertime projects.

 

Main reason for posting is that this morning, I blew the #9 fuse in the dash fuse box area. #9 is the fuse for the ECU, PCM, and the Quad. Drove to the gas station fine, got coffee and breakfast, went out to the truck to start it, and crank no start. Tried cranking again, had all the symptoms of a bad ECU, then i remembered about my fuse blowing previously, and sure enough it was blown.. had a spare 15 amp fuse to get me home but i dont want to play around with the power supply for the brains of the truck anymore than i have to. Drove the truck home, swapped cars and posting this from work..

 

I'm guessing there's a small break somewhere that i have to track down. But I'm also wondering if a health check from Quadzilla would be worth the effort..

So. Pull the Quadzilla lose and test that red/white wire for short to ground. 

 

Then I would test the power leads for both ECM and PCM. Again you need to unplug the ECM and PCM to verify.

 

While your doing all this look for mouse damage or rub damage to the power leads for all 3 devices.

Sorry for not keeping this up to date regularly... havent had proper funds to get things started/finished.. solved that problem though.

 

hopefully going to be posting a bit more now that pulling season is about to start.

 

Plans for this year are similar to previous years.. clutch, bump stops, traction bars, safety items for peace of mind, cylinder head if i can manage it.. probably not this year though.

 

still need to do some maintenance stuff and trouble shooting/fixing of some random odds and ends..

My fix was another job change, but glad things are turning around for you Mike.

 

Finally ordered a new clutch, sintered iron triple disk from kennys diesel out of kentucky. Also ordered a tubular crossmember to replace the factory one. Hoping to save some weight and make trans removal and re installation a bit easier.

 

Only problem is I dont think parts will get here in time to get them installed for my first or second pull. We shall see.

Meant to keep up with this a bit more but things didn't turn out that way. 

 

New job is going well, albeit the exhausted feeling every day is a bit rough.

 

Sled pulling season was a well earned 2nd place. Me and the puller that got 1st were going within feet of each other pretty much every race. 

 

New clutch worked well on the track but is a bit rough on daily driving. To be expected...

 

I will say being able to spin 3700 rpm down the track is helpful too. 

 

Got traction bars for Christmas so that will help...

 

Lots to do and I don't have an open garage to do most of them. 

 

Side bar.. I missed my last pull (Oct 21) because my brother and I helped my best friend move from the ct shoreline to tacoma washington. We turned it into a mini vacation. Visited Yellowstone and the LaMay automotive museum. @Mopar1973Man, I was gonna let you know that i was coming through but we were coming through on I90 i think.. I was a bit far north for a detour on our timetable unfortunately.. Next time hopefully...
