hdonlybob Posted April 30, 2015 Report Share Posted April 30, 2015 I have an older Safari Motor Home with a Honda Generator. Last fall the generator would not start, either from the inside starter control, or the one directly on the Generator. As long as you hold the starter button on, it will run, but the green light will not come on. As soon as you release the starter button it immediately stops. A friend of mine just told me that a lot of Motor Home generators will not run if the main coach tank is low on fuel, as it runs off of that. Mine is way low. I will fill the tank tomorrow and see what happens. Anyone have this experience, or know this to be true? Thanks much, Cheers, Bob Link to comment Share on other sites More sharing options...
Yarome Posted May 1, 2015 Report Share Posted May 1, 2015 Anyone have this experience, or know this to be true? In that type of setup, yes. It is true. Typically, they won't run below 1/4 tank of fuel in order to prevent you from accidently running your genny too long and leaving yourself stranded.

kathydavidb Posted May 1, 2015 Report Share Posted May 1, 2015 I've been running mine at least once a month for at least 30 min. run time with a load on it. If I do this there are no problems with it. A few years ago I didn't do that and it ran badly. That is, it was hard to start and when it did start, the voltage did not stay steady but fluctuated on the volt meter. So after that I've got into the routine of running it at least once a month. Besides just running the motor of the gen., putting a load on it seems to help keep the voltage steady at 120 V. I usually plug in an electric heater or run the A/C for a load on the gen. This is just what works for me and my gen. starts & works well when ever it's turned on. Dave. Link to comment Share on other sites More sharing options...
hdonlybob Posted May 1, 2015 Author Report Share Posted May 1, 2015 UPDATE:Put 100 gals of fuel in it today...still no difference.. Gets fuel fine and runs perfect only if the starter button is held in the start position.. Hmmmm....off to next chapter Cheers, Bob Link to comment Share on other sites More sharing options...
Kirk W Posted May 2, 2015 Report Share Posted May 2, 2015 It still sounds to me like you are not getting anything from the generator output, just as happens with a generator set by Onan. Have you done any electrical measurements on the generator output? Link to comment Share on other sites More sharing options...
hdonlybob Posted May 2, 2015 Author Report Share Posted May 2, 2015 Kirk, It is now over at a local shop where they are doing exactly that. I found some good info on the internet for this particular generator that gives five or six pretty good specific areas to check, as you suggest. My generator is a Honda EV6010 .

tjones1935 Posted May 2, 2015 Report Share Posted May 2, 2015 Some generators have a locking relay that energizes to keep the unit running but as Kirk said if no output then relay will not lock. Link to comment Share on other sites More sharing options...
Phil and Micky Posted May 3, 2015 Report Share Posted May 3, 2015 just picked up our 2005Phaeton. it has an Onan 7500 generator. they replace the temperature switch which was causing trouble. It ran good for several hours. It is starting to act up now. We are out on the road. It is hard to start of runs good for a while after it starts. I'm getting a three 25 error code. and I also got a 336 area code earlier today. can anyone help? Link to comment Share on other sites More sharing options...
Kirk W Posted May 3, 2015 Report Share Posted May 3, 2015 Since you don't say what model of Onan you have but your RV is diesel, I'll assume that the Onan is diesel also. Here is some information that I have collected by doing some searches since my Onan experience has been mostly with gas. Code 36 is Engine Stopped Without Command from Controller. It is almost always fuel related. ENGINE STOPPED FAULT—CODE NO. 36(Engine stopped without command by controller)Corrective Action:1. Gasoline Models – Check and fill the fuel tank, as necessary. (Note: The genset fuel pickup tube is probably higher up in the fuel tank than the vehicle engine pickup.)2. Low Pressure LPG Models – Check and fill the LPG container, as necessary. On cold days the LPG container may have to be kept at least half full to provide the rate of vaporization necessary to keepup with the genset fuel demand.3. High Pressure LPG Models – Check and fill the LPG container, as necessary, and drain the genset LPG system of oil that may have migrated from the supply system (Item 5, Page 13). Make sure tore-close the drain valve.4. Secure the spark plug leads on the spark plugs (Page 20).5. Replace the spark plugs (Page 20).6. Service the air cleaner (Page 19).7. Check for mechanical damage. An error code of 25 indicates that the governor was unable to control engine speed and says to take to service.

Phil and Micky Posted May 3, 2015 Report Share Posted May 3, 2015 thanks Kirk, 110 miles east of El Paso now... it's an Onan 7500 diesel... Still hard to start... Have to prime at least one minute each time to get it to start... Usually takes three attempts... Headed for San Diego hoping it lasts until then Link to comment Share on other sites More sharing options...
BandBuds Posted May 5, 2015 Report Share Posted May 5, 2015 This response is coming from Vern, "wrknrvr". For water cooled Honda generators, the best place for info is: Pinellas Power Products (http://www.pinellaspowerproducts.com/).%C2'> This company has you tube videos on total rebuild and technical information on water cooled Hondas. Vern has personally visited his shop and met with him, and he is extremely knowlegable on these generators. Safe Travels, Vern Link to comment Share on other sites More sharing options...
