Sure did! Two shiny new ones from Costco! Their warranty is essentially a "batteries for life" program. If you walk in with a battery purchased within the previous 36 months, they give you a cash refund. This allows you to go buy new ones off the shelf with a new warranty. The employees in...

Had some time... I finally had some time to work on my truck while the ol' lady is out of town. In my original post, I made a checklist of all the items that I thought could make my cruise control fail: I can think of a few things that could be causing the cruise control to not work: 1)...

Up until recently, I had weak batteries. I definitely tried to let off before it started to minimize the effect. I had several no starts due to weak batteries. If the engine does not start, there is no extra noise, or prolonged cranking. If I let off too soon, it immediately stops. If I...

I've been inside countless starters and alternators, but for some reason never really thought of just picking up the parts I need. Should I go to the stealer and get brand new bolts for it while I am in there? Should I threadlock them in so they don't rattle out?

For approximately 18 months now, during cold weather (sub 0°C, 32F) I have been getting a noise that sounds like the starter drive is not releasing for 1-2 seconds after my engine has started and I have stopped cranking. I called the rebuild shop that is literally 1-1/2 blocks from my house...

About 1500 miles from IL, but thanks anyways!

I just thought of one more thing that I am curious about before I start tearing out parts. My high idle still works, and switches off with the brake pedal. Does that verify that the brake switch is good, or is there a 3rd circuit that I need to check that is for cruise only?

In my cruise control thread http://www.thetruckstop.us/forum/showthread.php?t=18837 I have narrowed down my possible tests for cruise control diagnostics to include swapping out my PMD for a known good one. Is there anyone in the Saskatoon area that has a remote mount PMD, or an easily...

Yes, I followed the instructions that came with the GL4. Autoenginuity is on my list of things to buy with Christmas money. Don't really need it when I know there is a TechII available, but I would love the convenience!

Batteries are definitely weak, and I plan to change them within a week. We'll see what that yields.

Interesting. I'll have to dig the resistor our and check it out. Still a dealer installed Stanadyne unit that I moved to the bumper. Again, anyone in Saskatchewan that has an easily accessible known good PMD that I can try, I would REALLY appreciate it!

I've hit the connectors with dielectric grease a couple times to makes sure the connection is good. I certainly do suspect the PMD, and would like to get a known good one from someone in the Saskatoon area.

I do have the wiring schematic for the truck. Cruise control is built into the PCM.

Instructions for what procedure?

As far as I know, its one part for brakes, and one part for PCM. PCM = idle speed while coasting / braking as well as cruise cut-out. Am I correct, or is there a third part?

I've owned my 6.5 for a shade over 5 years now. :D Last year in February, I moved my PMD from the pump to a heatsink in the bumper. I used a chitty EDAM cable that worked poorly at best. Cost me a $50 tow, a week of diagnostics in the driveway, and eventually a new cable. Even with all of...

Sounds exactly like what happened when my extension harness failed. Try connecting the PMD directly at the pump to see if the harness is the issue.

A more extensive investigation can be performed with a test light. Open the fuse panel, and pull the fuses one by one. Run the test light across the two contacts in the fuse panel when the fuse is pulled. If it lights up, then there is draw on that circuit. Using a multimeter works better...

What you will find is that max fuel rate likely cannot be sustained in a no load situation, because the governor will cut fuel rate to prevent exceeding rated RPM. If the governor did not cut fuel rate, then the engine would be placed in a "runaway" situation, where the RPM increases until one...
