• Onan 12500 Generator On Ebay

I have a 2004 Discovery, and the Generator wii no start. I had not been using the generator this past summer, bit I ahd the oil changed in Aug. When we started home (from Oh. To Tx.) I tried to start it, but I had to prime it, then it started. After a week in the camp ground, we then continued on our way. We pulled in to a rest area and i I tried to start it.

It would not start. The start switch is a rocker type that you push down to start and up to prime. The prime has a lightening bolt on it that I think is a light.

This does not light when I pressed on it. I was thinking that a fuse was out. But after checking the fuses, what I could find, they were not blown. My mh is a 2004 Fleetwood Discovery 39l.

I am very confused by this post. What is everyone talking about when they say prime. These are diesel engines to the best of my knowledge you do not prime a diesel. The instant you get air in a diesel engine you have problems starting it.

If you lose a prime that would mean you had air in your lines and I would be willing to bet that you will not fix that by just holding a button in. Are you talking about turning on the glow plugs. I could see that happening if you pushed in on a button to turn them on then start it after they had heated up the cylinder. Could someone explain what they mean by prime?

Could someone explain what they mean by prime? Pushing and holding the bottom of the start switch activates the fuel pump. Maybe pressurize is a better word. I have a 1996 HR Navigator with a 10K Onan diesel gen. It periodically refuses to start.

The cause is the solenoid activated fuel shutoff switch which initiated by the rocker switch on either the dash or at the gen. I have found this switch to e a bit of a weak link with my gen, having replaced it three times in seven years. Not something I would have expected.

I try o carry a spare with me, but if you don't (can't), you can get the gen to start by using the preheat/start rocker switch at the genset and as you push it to start, also pull back on the fuel shutoff switch. There seems to be a weakness develop after a couple of years and this is the only way to get it started without replacing the shutoff switch. This happens to my coach regardless of the charge condition of my batteries. One other thing I notice is that if I haven't used the genset for some time, I have to do multiple preheats (2 or 3) before the generator starts. Had a problem with the 10KW on my 2001 Monaco.

A member here suggested the 'Onan Voodoo' solution. Start the engine first and then try the Onan starter. I don't have a clue why this worked but it did. Voodoo, If you have to ask, you won't understand'.:-) One more thing, get out the Onan manual and read the starting instructions. Mine does not suggest using the fuel pump 'prime' to start the Onan unless the filter has been replaced. The start position will produce the same 'clicking' sound (fuel pump running) as the prime position until the starter engages.
