Thanks posting the link by Mark. That is what I was looking for. Will keep informed, Vern

So there at the right top of the ECM is the fuse holder. I was directed to this problem from Terry Chron YouTube videos. He covers some Cummins engine diagnostics. Very informative about some odd things to check. He stated that if you have 5or 6 volts on the fuel solenoid with the key off. That indicates the ground fuse is bad. Yep it is bad looks good , but is bad So it may have taken the ecm out. It starts easy idles, but when u give it throttle it has a miss. It could have a problem with the wiring harness as I had tried something about a ten days ago the indicators it could be a plug connector. Not sure if every time or not. Tired from doing things to beat the rain. Terry also suggested to run the ground directly to the batteries. Unfortunately Terry passed away a few years ago. But his daughter Breanna still supplies parts and helps with diagnostics.

Thanks for posting it . It does work with you access. Going out now to physically locate the ground and where it attaches to the battery system. I did another test and it shows the ground is bad.

I need to look at the wiring schematics for a 2000 year, model 610 wiring schematics. So I looked in the resource guide for the Volvo manuals. But after clicking on information. The different manuals appear, then they disappear. No time to click it. What I really need is to identify the ground wire for the engine ECM. This is on a Cummins N14. Will search the net if need be. Or call Volvo. I think Mt ECN ground is bad. According to a technical person on these engines. But he has no idea where Volvo grounded the ECM. Will look for what wire is ground on the ECM and follow that to find the grounding problem. Thanks in advance, Vern

Fuel filter

Dry gas needed, possibly. We are in South Carolina for the winter. I have been adding dry gas most of the winter to my Jeep that has a Chevy 350 with a Holley carburetor. Or it wants to miss some, or diesel when I shut it off. Just thinking about a simple solution to your situation.

When was the air filter changed last. I had a friend that was frustrated at his Ford motor home as it had lost some power. His home was flooded in Florida and he wanted to get back. Pushed it so hard the transmission went out. Had the trans repaired while he went home in his car. He drove back to the rv a week or so later. Engine still was real short on power. Took unit to a Ford dealer. Nothing showing up as a problem. One mechanic said to check the air filter. Totally plugged air filter.

I was careful to chase the threads in the splitter female fitting. And chased the threads on the brass engine side elbow to a point that I could get the fittings to be tight at the correct position. Applied some rectorseal number 5 pipe thread compound. Made sure the o ring side of the female splitter assembly was flat, and put the fuel splitter together. I was tired, but I did replace my first fuel filter. Late in the day and had a lot of stuff to cleanup and put away. So I started the engine. It will sit there and idle as it should. Previously it would idle, but when the throttle was pushed down, it missed a lot. After doing what I did yesterday it will take fuel but there is still a miss. It may not be the same cylinder. I need to replace the other filter later today. Busy with other things this morning. I am thinking possibly the fuel solenoid. I had that do similar things years ago and replaced it. It solved it that time. Will try to test it later today. While looking around at possibly other problems, I found the ecm fuse holder cover is gone. Yep, someone stole it. Maybe a squirrel. About 2008 the original fuse holder had corroded and give me fits back then. I had a mobile mechanic stop by to check out what was happening. When he got there I showed him what the old fuse holder looked like. I found it as he was on his way. Started the truck and problem solved. Had him check with his computer and he said it’s all good. Paid him, and thanked him.

So I have been polishing my fuel. While I was waiting for a new supply fuel splitter. Slow but steady. I did put additives in before I started to polish the fuel. It arrived, but it is a return fuel splitter. Sending it back. So took it apart to see if I can make it work. 1/2” supply female pipe threads are just loose enough that it will not thread correctly. So I need to tap the threads 1/2 turn deeper. I think that will make the threads tight as it should be. It was loose when I tried to see if it was a problem. On my truck the supply line comes from the frame rail and makes a 90 degree turn. Apparently from wear from vibration. I also need to run a pie over the engine supply hose fitting to make it true again. As I was taking the fuel splitter apart, I only got, at the most a shot glass full of fuel out of the pipes and splitter valve. Will keep informed.

I use the vise grip style that Darryl posted. I have two different models.

I just looked at my fuel filter. It does not have place for a wrench to fit the bottom. But I did spy two different filter wrenches I have. They are vise grip style filter wrenches. I have two different versions of them. I would take you new filter with you if you go looking for wrenches. I also use them for holding awning tubes when working on awnings. Harbor freight may have them.

There are cast aluminum filter wrenches that would fit the bottom of the filter. Usually using a 3/8” ratchet. That way it is centered on the bottom of the filter. I would say to buy a good quality one as I have found a poor quality one once and had to go get a good one at NAPA. Although I do not like NAPA filters. I tried to pate a picture, but I am not a computer person. So I failed that test. Search the net and you can find them.

Just let nature do its thing with lots of water.

Last night it rained over a inch, so I was doing other stuff today. But then I thought I will drain the first filter inline. It has a drain on it. No water? And vary little fuel. At least not like I thought should see coming out. Now what? Maybe 7 years ago I had problems with needing to put fuel filters on occasionally. Was not really thinking about said situation. But I do remember the filters being low on fuel. An finally ended up discovering that there is a fuel splitter under rear of the cab. Fitting was loose feeding the fuel to the engine. Tried fixing it a time or two. Finally bought a new one and installed it. Fixed that filter being empty problem. So I put on old clothes and some tools on a cardboard box. Started the truck to pump up the airbags. I did not get skinny enough with out he System aired up for clearance. That fitting is loose again. On my truck the fitting has a 90 degree turn so the fuel line comes from the frame to the fitting. So that 90 degree turn has the weight of the line helping to put pressure downwards. What is does is where the threads different. Last time I tried to clean the threads up with a tap. But that did not work long term. So ordered a new splitter. At least I checked that before going further into wanting more parts.parts. will keep informed

I do have three or four filters for my testing on Aquahot Systems for work. It has a clear sediment bowl on it. So I can see what enters the bowl quickly. I think I will hook it up tomorrow and see what happens. I am always outside doing things, so I can hide what I am doing. I think I have enough fuel line with me to do what I want. But I want to check my filters first. The big problem is to get shinny enough to slide under the truck and check that old splitter fitting that caused problems years ago. Now twice while I have been working on the truck I did smell raw fuel. That could be a indication that that fitting is leaking again. Sorta forgot about that. I want to check that fitting before I start the truck. I do have a compressor and there maybe a fitting to air up the suspension without starting the truck. Or dig for clearance.

I just tried looking into the fuel tank with my remote camera. All I see is black. The light from the camera just reflects off the surface of the fuel. Tried on a small fuel tank for the Aquahot storage tank. Same thing , the light on the end of the remote camera just does not penetrate the surface. Although I can see the black spot without the camera. Learned something new today

I think once I drain my first filter that has a drain on it I will decide what to do. I am thinking of adding the treatment to the tanks and circulate it for a number of hours. It is about to start raining for a few hours, then when it stops I will try to get my remote camera in the tank and look forwards in the tank. I will test my pump system on a fuel tank I have for the Aquahot unit. I was thinking of putting the pump in that take to check it a few weeks ago. I originally was leaving in a week. Buuuutttt that will be postponed. Or is it fuel and electrical combination that is a problem. Thanks for all the help, Vern

I usually check my takes several times a year. Never seen this before. I am thinking of putting a fiberglass rod in the tank and see if that black spot will distort if possible. On draining my tanks, I am sitting in a campground.?

I took this photo about 8:30 am today. I cannot see a water line in the fuel. So I will probably get the paste for testing water in the fuel tomorrow am. We are going to have storms today. So just staying at the campground today. And read and watch videos on what to do. I did get a bio kleen and a Clear -diesel treatment to use. Back about 10 years ago I had dealt with a leaking fitting on the splitter valve under the cab, that deals with fuel evenly. Eventually I replaced the valve to solve the problem. I will crawl under the truck tomorrow am, or when it is dry under there before I do the tank stuff.

I am hoping to find some water detecting paste today locally. Then I can find out how much water is in the tanks. If any. I do have a 12vdc fuel pump with me to transfer diesel to my Aquahot fuel tank. I also have a filter assembly with me that has a clear sediment bowl on it. Although it is a low volume pump. I can see a few black blobs on the bottom of the right tank. I need to look at YouTube videos on how to do this, as for a good way to put the treatment in. Should I just pour it in, or pump it in to the bottom of the Tank. The truck is sitting down hill enough that it is not level. I also have a remote camera that I can see maybe 30”. I am thinking this will be a learning curve for me. I also think I may stop at a local farm store to find some useful information tomorrow. It is raining here today, but will test the one filter that has a drain on it tomorrow before I do anything other than testing for water. Thanks for your help, Vern

Thanks for your input Darryl, I think I found a culprit in my tanks. I would say it is not covid. As it is black in color. Like sludge some may call it. I looked into the tanks and it is there. So now how do I remove it. I am thinking with a pump, filtration system and possibly pump the fuel into the other tank. Then what treatment do I use in the tanks. I an going to try and find my assorted things I need today to accomplish this task. So should I clean out as much of the black stuff as I can with a pump. Or how do I solve this situation. I think I should not start the truck again until I deal with this. Then I will check the filters and replace if needed. Also get extra filters while I am out today. Thanks in advance for questions or comments. Be it be good or badddd.

Yesterday I finally had a chance visit a Black Powder Cartridge Rifle shooting event. It is a silhouette rifle competition. I drove 3 hours to get there, North east of Atlanta Ga. that part of Georgia is fairly hilly. A good place for a shooting range. So after introducing myself, go place my equipment and rifle on the cleaning area bench. Then the match director and a shooting instructor inspected my rifle and asked several questions. They decided I could shoot yesterday as it was only a practice session. Today and tomorrow is the competitive competition. This range has 200, 300, 400 and 500 meter targets. They are a chickens at 200 meters. A hogs at 300 meters. Turkeys at 400 meters. And a Rams at 500 meters. They did have two white targets with black dots at 200 meters. So the person that teaches shooting was my first spotter. Squeezed my first round off. High dead center about 12 “ from the center of the target. I asked if I could quit. I did shoot more rounds at that target. What i did learn yesterday was my eyesight is better than last fall when I was shooting. I did learn more on my scope situation. Remember that the rear hole to look into is adjustable by putting a different muzzleloader nipple in the rear of the scope tube with different size holes in it. From like 31 to 61 thousands of diameter. I was missing one that is 42 thousands Dia. So there was some comments about this rifle. Like what is it. Are you kidding. All the other people there had spent a fair amount of money on there rifles. Twice I was asked about just buying a real rifle. But would take the fun and frustration out of this subject. I finally asked if I could shoot at 500 meters at a ram. The ram is 26” high. i adjusted the rear sight setting up 3 more turns. I don’t know if they used clicks back in the 1880’s. I have rotations on a 32 thread per inch adjustment. I squeezed a round off. Now there were two spotters watching. This is the first time tried shooting at this distance. 500 meters is about 542 yards. I missed the ram? But I hit a Turkey at 400 meters, that was directly under the Ram. About 6’ lower. Yes I knocked it over. That counts as a score. Maybe The one spotter was the match director. He looked both ways on the firing line. No one else fired when I did. I adjusted up another turn but apparently I was hitting in the grass below the Rams. I can say the match director was curious intrigued.

Could it be water in the fuel. Will look in the am. But busy with other stuff to be doing tomorrow. Will check the filters hopefully on Saturday.

Today I decided the weather was good to work on the truck. First of all I did get two pass through connectors for the cylinder head. The diagnostics was saying number 3 cylinder was the problem. So I was looking at putting the pass through in. But first I decided to make a tester for the injector wiring, as now I had a way to hook a noid light into the wiring fairly simple. Get it hooked up to. Started the engine . Runs as expected. Close to 20 minutes idling. Temperatures came up. Checking things so I decided to give it some throttle. Not good. Miss firing a lot, when rpms are going up. Let it idle and it sits there doing its thing as it is supposed to. I believe that since it has rained here this winter a lot. I am thinking water has run down over the wiring and ecm. Will get back to it next week. Will keep informed.
