I have a 1976 Eleganza II with the original generator. It turns over but will not start. The mechanic says I should just replace it. Any thoughts on repair?

did you check the defaults? Enough oil, enough gas?

Find another mechanic.
Jump terminal 5 and 9 to bypass safety's and prime the fuel pump. All ya
need to do is figure out what the problem is and fix it.
Make sure it's getting fuel consistently. At least 25 gallons of fuel
available with coach sitting level, Non porous fuel lines, working fuel
pump, clean filter(s), screen in the bottom of the fuel pump clean.
Make sure it's getting spark. Spark plugs, wires, Points, capacitors, or
electronic ignition (the cats meow!).
It's a very simple system. Replacement is a lot more trouble and cost and
might not be any better.

yes. Fix it. Get Duane Simmon's troubleshooting guide for the Onan Power Drawer. Step - by - step till it runs

Ron - Replacing the generator is a $3K minimum to perhaps $5K depending on lots of factors. Is your mechanic a generator specialist? If not, it could be something simple most of which you can check yourself using a meter. Mine had the same symptoms recently and it turned out to be a split fuel line in a hidden location, a $5 fix. Where are you located, in case there is someone nearby who can assist you.

Ron,

Is the "mechanic" and RV mechanic?
If he is, go find a small engine shop. They will have had lots of experience dealing with this family of Onan.
Go to Bdub's first and download all the stuff for the NH Onan that you can find. Then do as suggested and get the Duane Simmons stuff too.

If it does not start and run, that is an engine only issue. The only thing that the engine end and the AC end have in common is the shaft between the
two and the coach that carries it. The engine design qualifies a neolithic (New Stone Age). No Rocket Science here.

With the withdrawal of the Honda 6010 from the market, there are not many replacements that are worth the investment.

Ron, I went through the same thing with my 75 Glenbrook a few months ago
just learned from the manual and Jim Miller how to diagnose the problems
turned out to be an easy fix ( points ) Jim K. Has all the parts.Very glad
I didn't replace mine it runs great now, they will go thousands of hours.

Alcohol laced gas sitting and turning to jelly is an issue for all small gas engines today. Seems we have to clean out the fuel system every year on everything from string trimmers to pressure washers to generators.

For less than $300 you can order a kit from USCarburetion that will allow your Onan to run on either propane or crap gas at the flick of one toggle switch. If it runs at all now, even poorly, it will run far better on propane. If it doesn't run now, it is far cheaper to add an electronic ignition (to eliminate faulty ignition issues) and a propane kit (to eliminate all the crap gas issues) than it is to change out the Onan for something else. Add these two and run a 12dc switched source to the positive side of the coil (to eliminate bad board issues) and it will run like a charm for years to come. Just keep an eye on oil level and you are good to go. Low oil shutdown is the only rational thing the pesky board did anyway. Max investment? Around $500.

There is a reason all new gas motorhomes use propane generators with electronic ignition.

Ideally, a good running OE 6-Kw Onan power drawer is the best option, maybe the only option of you want your batteries in the rear. At their current
age, they tend to be somewhat problematic and people like to replace them, but they were MADE to fit the coach.

Unless the problem is in the AC end (and that can be fixed too) they normally will run with a few basic repairs. Fuel pumps tend to be a problem
along with the lines feeding them, coils seem to go out, but rarely, and the control boards have issues sometimes, along with the LOP switch. The
design and the RPMs they rum make them run virtually forever.

I recently replaced my high hour Onan with a "refurbished) unit I bought from another GMCer, After having problems with the fuel pump and the ignition
on the 'new' one, I was kicking myself for changing my old reliable unit for the refurbished one, but since fixing a few items, it runs great.

I still have the old generator, complete and would like to get what I can out of it, but I am in Tucson, a rather long distance from you. Plug: If
anyone who is coming to the April, 2018 GMCMI is interested, it will be available.

Or find a good lawn tractor guy with grey hair. Onan put thousands of these boxer engines in lawn tractors. It's either no fuel or no spark. Often
not the generators fault but bad aged out fuel lines or pinched fuel lines. Mine starts as soon as my finger touches the button. And runs both ACs

Easy way to start troubleshooting is to see if it’ll hit off on a snort of starting fluid while cranking. If it DOES then ignition is working and you can go after a fuel problem. If it DOES NOT hit then work on the ignition - and once the ignition is working then re-evaluate the rest.

To reiterate what others have said - always always always jump terminal 5 to 9 as the very first step when troubleshooting. This bypasses a lot of common failure items on the control board and helps with the process of elimination.

I would get out my tape measure and measure your current gen compartment physical size. Then measure the required dimensions of the Onan for a
semi-enclosed compartment. This is in the Onan installation manual. That should make your decision easier.

The chinese 7500 from Harbor Freight will fit. It will also fit the 23'. Currently $529 on sale, figure an extra hundred for baffles, a
pulse fuel pump, exhaust extension, etc. Here's how it was done in a 23' :

Johnny, is there a write-up that goes with the photo?
If I wanted to copy what you did I would at least want to know what you
were doing rather than just remove and replace the genset.
Why was the panel modified? What does the pulse line do and how does it do
it? Did you convert to electric start? How?

Lessee. It comes with an electric self - commencer, I used the 7500 because it was the littlest one they had with an electric starter. The way I
mounted it the yanker cranker was accessible, so you could fit one of the smaller ones manually cranked. Given that the smaller engine has a casting
for a starter pad, depending how good a machinist you are you could fit a starter to a smaller one. Ken Henderson found a TroyBilt with the smaller
mill and electric start.
The panel was modified because I was too lazy to take a piece of plate and make one. Which I'm sure the N.O. has done. I gave him the Jukerac which
the space was initially cut for. The 23' genset bay is smaller than the 26', so baffling and perhaps placement will be different. Exhaust will be as
well. There was a short pipe from engine to muffler, I cut it in half and had a local welder put short pipe sections on each end. They're connected
with any length of flexible stainless exhaust tubing from Advance or elsewhere.
The pulse pump is necessary to fuel the set, you cannot use an electric pump. The pressure of even the lowest will overcome the carb and flood the
engine. The pulse pump is common to larger lawn mowers and works well here. ten bux or less on eBay. Eventual plans were to pick up the crankcase
pulses someplace else, but again time dictated the approach I used. Checking the oil is cumbersome. Beyond that it works well.
The writeup would likely be a catalog of somewhat original cursewords. Note the placement of the outboard cooling fan. It was there when I got the
coach, and was a consideration when locating the set.
Had I kept the coach I'd have made some minor mods... a solenoid on the choke - or at least a pull rod. A panel made for the space. Which would
dictate a better overall wiring layout in the compartment. Different baffling for the cooling air. Note that I was able to get a lot of space around
the exhaust pipe, I consider it necessary. Pay attention to the airflow through the alternator. Straightforward 'in the door out the bottom' doesn't
address the flow through the alternator, which is opposite to the engine. In the contractor frame it blows out the bottom and the engine air out the
back. When we put sides on it changes. I was contemplating a short piece of flex hose on the rear of the alternator routed properly. Your routing
and baffling stuff will be different.
Another mod I'd do on the 23' is relocate the air filter. Remoting it will shut it up some, and put all the service ports on the door side of the
genset bay. You might even consider a silencer on the hose, input moan at load is a substantial point of the noise it makes. Wasn't so bad in the
coach, the set was under the bathroom. If next door was close he might of not liked it. If his A/C was on he wouldn't notice it.

John, I dunno how the CA smog set differs, but HF offers it as 49 state and CA compliant. I doubt there's much difference.

Hi Steve, That is a very sophisticated contraption for such a small bo=
x (approx. 14x10x8 inches). It appears to do many desirable things well. =
Note however that it requires 230 VAC for input and our Onan generators onl=
y put out 120VAC. Note also that you have to request the unit be reset fro=
m 50 to 60 hz that we use in NA. If you are thinking of ditching the Onan =
and using one of the manual start, manual fuel Hondas it looks like it woul=
d work well and fit well in a GMC. Get a long extension cord to get the no=
ise from the Honda away from you and your neighbors. Do a search for peopl=
e who have actually used any of the Li technology batteries in an RV applic=
ation. Heat management is a must for long battery life and to maintain the=
battery capacity over an extended period. The Victron stuff I have used i=
s very high quality and performs as advertised. I may look into one of the=
se when I decide to replace the Heart modified sine wave inverters in our P=
revost since the 17.5 kw generator there puts out 230VAC and we already hav=
e a very large AGM battery bank (6 - 8D batteries) and auto gen start. =

The harbor freight one is half the price. I doubt the Honda will outlast two of them.
