Re: UPDATE. Generator problems Reply #25 – July 28, 2019, 03:12:29 pm So Napa part #3046, is oReilly #33046, cost is $3.50. I replaced mine on 8K today. Had rust, water, for the visual eye to see. Ran Gen. Ran well, but will have to run with load and time to see how it goes. Did find that the professional's, when putting on new hose, had it too long causing a crimp or less then full flow in fuel line. M Quote Selected
Re: UPDATE. Generator problems Reply #26 – July 28, 2019, 03:43:33 pm While the fuel lines from the tank to the generator are ⅜" the short pigtails from where they terminate, the short rubber lines that hook up to that small round filter screwed right onto the pump are 5/16", at least on our 99' U270. It is pretty obvious when that line leaks!DonQuote from: Texhub – July 25, 2019, 09:32:59 am4. Fuel lines 3/8 inch. Make sure you use diesel compatible line. When in doubt, if you have the length on current line. Cut off 1", reattach. This "may" remove possible degraded line at last point.Fuel lines from tank. Many have had to replace these to fix issue of. Strange running, rpm up/down, then load drop.There is a very good write up on how to best do the replacement. By Grover D. Look at it. Quote Selected
Re: UPDATE. Generator problems Reply #27 – July 28, 2019, 03:49:20 pm Keith, we have the same gen and I have never so far seen any lights come on. In fact, yesterday in the blazing heat, when we arrived at our destination, I fired up the gen, it ran for about 3 minutes and shut down and restarted in about 30 seconds. Then it ran for about 10 minutes and shut down again and restarted itself again. Has ran fine since and no lights showing any issues. Another thing I noticed on this year coach, when you push the start switch, you don't hear a sound, but let go of the switch and gen fires up. On or '98, we could hear it turning over and once it started, let go of the switch. Not sure if this is normal on this one or not. Does your gen do this? Oh, it ran all night last night with no issues and fired up today when we needed it again, but like I stated, no sound, just let go of the switch and in a few seconds, it fires up. Strange or is this normal? Quote Selected 1 Likes

Re: UPDATE. Generator problems Reply #29 – July 28, 2019, 04:13:14 pm Yes that is what mine does too. If you have the motor door off I can hear a click and a little hum just before it starts Quote Selected 1 Likes
Re: UPDATE. Generator problems Reply #30 – July 28, 2019, 07:22:43 pm Thank you Ron and Keith! I know that on my '98, you heard the engine cranking. Good to hear that what I experienced is normal. I have over 3k hours on this generator and plan on adding more as we go! Quote Selected
Re: UPDATE. Generator problems Reply #31 – July 28, 2019, 08:02:16 pm I had a problem with mine running about 1/2 hour then shutting down. Checked oil level and it was a pint over filled. Drained a pint out ran forever without shutting off. Bear in mind mine is a propane generator, don't know if this has any bearing on y'alls problems. Quote Selected
Re: UPDATE. Generator problems Reply #32 – July 28, 2019, 08:33:02 pm Ours has 3232 hours on it..making plans to pull the manifold to fix it Quote Selected
Re: UPDATE. Generator problems Reply #33 – July 28, 2019, 08:42:39 pm If the end bearing has not been changed would strongly consider it,on my 8K it was dry at 1450 hours. Quote Selected
Re: UPDATE. Generator problems Reply #34 – July 28, 2019, 09:08:18 pm I took my coach into Mr Wrench, a Powertech service dealer in Shipshewana, Indiana Friday. Explained my issue of it starting, then cutting off and it took 2 times to start it but then it ran fine the whole time I was there. They tested oil pressure sensor, temperature sensor, etc, the only thing they found was a ground wire not attached in back of the motor ( might have come loose from vibrations). They cleaned my radiator ( got rid of a lot of Arizona dust), etc and ran it with full load for an hour. Nice folks, charged me for an hour labor ($85.00) and suggested I run my generator while in the area and come back if I have any problems.Today after my grandsons went home, I disconnected from electric and fired it up. Again it died, but I went outside , reset, started again and died, Tried it a third time, it fired up, ran smooth, I put full load on it ( both air conditioners) and ran it for over 5.5 hours. Turned off the air conditioners , let it cool down a little and shut it off. Will run it again tomorrow and see how it does. Strange how everything checked out fine, yet it takes 2 or 3 times starting to keep it running. We shall see...................... Quote Selected
Re: UPDATE. Generator problems Reply #35 – July 28, 2019, 09:15:44 pm Glow plug issues might explain starting, but I am leaning towards fuel delivery. Intermittent Any fault indicators on the shutdowns? Quote Selected
Re: UPDATE. Generator problems Reply #36 – July 28, 2019, 09:28:53 pm no fault lights on shut downs except when they tested things at the shop and it did show a code then. The fuel pump and flow was tested also, and I recently changed both fuel filters. If it is glow plugs would it start at all? Strange issue for sure............ Quote Selected

Re: UPDATE. Generator problems Reply #40 – July 28, 2019, 11:54:15 pm Working on diesels in my travels. You are showing signs of air in your closed loop fuel system and or pressure leak down. So how to fix this issue. Fuel lines, filters, pump all at top performance. Inserting a clear fuel filter into fresh fuel side might show any air in system. Placing it between fuel pump and final filter. draining both fuel filters into clean, dry, glass. As the 3046 is low cost, Just replace it. keep as emergency spare. If you were leaking at injector, should see smoke at start. rough idle. Even though you have tested pump, thats the heart of fuel system. its electric, so its wires could be damaged inside wire runs, bad connections, sand, clean, reattach, internal seals could be damaged. I am awaiting a new fuel pump for my spares. "Thats what I would change out". "In this troubleshooting". Glow plugs, test them. "Danger" Glow plugs reach extreme temputure, never handle a wired plug. Our engines stop running because fuel stops flowing. So if the power to fuel pump is being disrpted, that would cause this issue. pull a fuel sample from the return side of fuel system observe fuel flow from the return side.Diesel engine - air, fuel, compression.

Re: UPDATE. Generator problems Reply #41 – July 29, 2019, 05:33:18 pm I agree about the potential fuel issues but I don't understand why it would run almost 6 hours with full load on it if it were leaking air or fuel. I just fueled up Friday but the last time I got fuel was the beginning of May, yet my Cummins runs fine all the time. I will check fuel lines, connections, etc. At least it is running now- thanks for the ideas!! Quote Selected
Re: UPDATE. Generator problems Reply #42 – July 29, 2019, 08:03:33 pm I now have manual on engine. I will start studying it. With emphasis on how we actually shut down our engines. The steps that happen when we touch monetary switch on dash. Or switch the switch on remote. Also maybe I can trace fuel path. Quote Selected
Re: UPDATE. Generator problems Reply #43 – July 29, 2019, 09:12:23 pm I have not seen a 3046 style filter on mine, 1 filter is on the side of the motor, a screw on and there is another screw on under the coach kinda behind the step.. should I have a 3046 style too??? Quote Selected
Re: UPDATE. Generator problems Reply #44 – July 30, 2019, 12:40:51 am Keith, Ours, which should be the same as yours, uses a Racor R12T (or NAPA 3583) as the primary filter, and a NAPA 3390 as the secondary. Quote Selected 1 Likes
Re: UPDATE. Generator problems Reply #45 – July 30, 2019, 04:11:51 pm Today I started my generator, fired up first time, smooth and easy. Put a full load on it, never missed a lick. Perhaps it was the loose wire? Perhaps I needed to run it longer? Seems to be working fine now............happy happy................... Quote Selected 2 Likes
Re: UPDATE. Generator problems Reply #46 – July 30, 2019, 04:44:09 pm Well 1hr 9 min, mine had an rpm shift. shut off ac. noted as i passed that voltage was changing. took temp of radiator 217. restarted. ran as if on 2 cyl. shut off. restarted 30 min later, ran smooth. so I am now looking at status of cooling system. so it goes Quote Selected
