The150 AMP alternator fuse holder is mounted on the outside lip of the right battery tray. I had to drill a hole through the fuse holder to mount it.

Try applying heat to stubborn bolts/nuts next time. Mapp or acetylene gas torch will do it.

You are right about the retractor having the switch in it. From the FSM: "A seat belt switch is integral to the driver side front seat belt retractor unit."

The "W-T ground wire mod". This moves ECM, VP and grid heater grounds from the left battery to the right battery.

I second what @Tractorman recommends. last October, while on a trip to the Portland area, my alternator shorted to ground. The short blew the 150-amp fuse, similar to the photo above. I had installed it after doing the "W-T" modification. With out that fuse and the properly gauged wire there could have been a catastrophic fire under the hood.

That is caused by high resistance by either open circuit or a bad ground. OHM test those circuits for a problem it might help you with the other problems.

Maybe a different blend. Found this online: "Biodiesel generally yields lower fuel mileage than conventional diesel, with a roughly 10% decrease in efficiency for pure biodiesel (B100) due to lower energy density ( content). However, common blends like B20 (20% biodiesel) typically show negligible differences in performance or mileage compared to conventional diesel."

What's the pin weight, empty/gross, on the truck's rear axle? Is that 16k lbs. empty or gross?

Same speakers I put in my truck three years ago. They sound all right. My son says I should put a small base thumper under the seat so that I can "feel the music". Just what I need to go deaf faster.

Nice dash cam. I have a dash cam in all of my vehicles, not as nice as yours but it's cheap additional accident insurance for when the other driver says, "it's not my fault". Case in point when a truck pulling a trailer ran the trailer into my right front fender. He was giving me a song and dance about it until I said " do you see that camera in the windshield? It's recording everything". He then said, "I guess you got me". His insurance company was giving me a bad time about paying the claim. I told them to grab a box of popcorn and watch the video on You Tube. They paid up. https://www.youtube.com/watch?v=5mTHYzV5IT8

Sounds like a "hell of a drive".

Congratulations!

If your generating high boost pressures, then yes; a lot of air going in then a lot of air needs to go out. That depends on if you want to hear yourself. My truck only has a resonator, and my wife always complains on how loud it is. Someone else will have to answer that question. I have a Magnaflow 4" 304 stainless steel turbo back exhaust system, cost $300.61 but this exhaust kit is no longer available. I installed it 20 years ago and have had no problems with it, but I live in SoCal where there isn't a rust problem, and I have only put a little over 102k miles on it in that time.

I don't race and not about to freeze my A$$ off in the cold winters of Southern California.

I had the lines off and had the insulation in stock so why not wrap the lines, no harm no foul. The heater valve shutoff valve is a good idea. What type of valve and where was it installed?

No, I haven't since this filter is on the return line from the power steering box and has the most fluid flow, I would assume the magnet in the power steering pump would have the same or lesser amount of metal on it. Besides, taking the magnet out of the pump is a lot of work that I feel is not necessary at this time.

Glade to hear it. This means that GoECM fixed what ACS could not. A big plus for GoECM.

I was thinking about how long the stock radiators lasted verse an aftermarket replacement. Could you tell us how old and milage on the original radiator when replaced and what brand was the replacement if known. If you bought the truck used and don't know the answer to the above question but have had to replace the radiator, please tell us the milage, how long you think the old one lasted, and replacement brand. Thank you, IBMobile

You can contact engine rebuilding machine shops in your area and see if they have any lying around or maybe order just one from them.

The input shaft is stock. I haven't gone wild with power upgrades, just enough to tow comfortably.

When the trucks transmission was rebuilt a Goerend triple disk torque convertor with a stall speed of 800RPM along with a billeted flex plate was installed. My line pressure at idle is 90PSI+ and the truck has an E-brake and is setup for towing a 5th wheel with a boat behind it so having that heavy duty convertor is a must.

I hope they find what the problem is. Please let us know how it works out with this ECM repair shop so we can update the article "List of Verified and Reliable PCM/ECM Rebuilders" in the 24 Valve 2ed generation engine section.
