Step One: Fuel Suggestions

The initial step is to make certain your fuel tank is full before letting it sit for anything longer than thirty days. A partly full fuel tank permits condensation to form inside the tank which not only includes water to the mix but can likewise result in rust forming and triggering all kinds of concerns. A lot of experienced RVers determine their storage/winterizing schedule and let the fuel tank get low before storage so they can fill it with the appropriate fresh fuel before storing it. This is specifically essential for diesel Recreational Vehicle owners. Fresh onan generator recommends filling the tank with a winter grade fuel as noted in their owner’s handbook if the temperature level is going to dip below freezing.

Diesel Generators

Use any of the following ASTM accredited fuels for your peaceful diesel:

ASTM-No.2- D (ambient temperature level greater than 23 ° F) (No. 2 Diesel). or ASTM-1-D( No. 1 Diesel). No.2-DLS( ambient temperature higher than 23 ° F). No.1-D (ambient temperature of less than 23 ° F). No.1-DLS( ambient temperature level less than 23 ° F).

B5 Biodiesel (ambient temperature level greater than 50 ° F).

Make sure the fuel selected for usage has a minimum Cetane variety of 45. No. 2-D or No.2-DLS diesel fuel gives the best economy and efficiency under most operating conditions. Usage No. 1 diesel fuel when ambient temperatures are listed below 32 ° F and during long periods of light engine load. Utilize low sulfur or ultra-low sulfur material fuel having a cloud point of at least 10 ° F listed below the most affordable expected fuel temperature level. Cloud point is the temperature at which wax crystals start to form in diesel fuel.

B20 Biodiesel.

Using B20 biodiesel needs the alternator to have an additional fuel/water separator. Long-term storage of biodiesel fuels can lead to oxidation and/or mold development. Consult your car manufacturer and your machine owner’s manual to see if this choice applies to your generator.

Gas fuel generators can utilize routine unleaded or an Ethanol Blend not to exceed 10% Ethanol. The secret is to utilize fresh gas, absolutely nothing older than thirty days which is why it’s a great idea to run the tank low before refilling before storage.

New LP Generators

It’s a great concept to use fresh gas and a complete tank for your RV, an LP alternator is not impacted by the fuel used for the drive train. Onan does have recommendations for the type of propane: Usage tidy, HD-5 grade liquid propane in a mix of at least 90% gas. Propane fuels aside from HD-5 can contain more than 2.5 percent butane which can lead to bad fuel vaporization and bad engine starting in outside temperatures listed below 32 ° F.

Step Two: Support The Fuel Supply.

Any fuel will deteriorate as it beings in an engine or fuel tank for some time, usually as fast as thirty days. Gas will start to varnish producing a gummy residue that clogs the carburetor, fuel filter, and fuel pump and impacts efficiency. Unlike engine performance or fuel economy, the octane level or grade of fuel has little effect on the time factor of this fuel wear and tear. Diesel fuel does not weaken and produce varnish-like fuel, nevertheless, it can suffer biological development (algae) and gel in cold weather which will also impact engine performance.

It is suggested to use a quality fuel preservative and stabilizer with either diesel or gas designs. There are several brand names on the market with most of the popular diesel stabilizers readily available at the significant truck stops. Onan recommends OnaFresh fuel preservative and stabilizer.

Bear in mind, as soon as fuel starts to weaken and varnish is present in the generator, a preservative and stabilizer will not restore the fuel. At this point, you will require to try a fuel system cleaner or take apart the alternator  elements and clean/remove the contaminants.

Step Three: Run The System.

The next action in how to winterize an RV alternator is to run the unit under load for a minimum of 30 minutes. The power cell owner’s manual recommends 30 minutes plus 2 minutes for each foot of fuel line to make sure the stabilizer makes its method through all the lines and engine parts. Other service documents recommend running for 1-2 hours. Running the system for 1 hour must suffice and make certain you have something on inside that will supply a load to the well running alternator like the roof air units or plugging in an appliance like an area heating system.

Step 4: Modification The Oil And Filter.

It’s important to use the maker’s original parts for oil filters and advised oil. These parts often have inferior products used for filtering, sealing, and longevity which could cause pricey failures.

Onan has combined their specific oil branded as OnaMax, nevertheless, they do permit other brands under guarantee as long as they satisfy the following specs:

Gasoline Engine Oil Quality.

Usage oil meeting any of the following API efficiency classifications: SJ, SL, or SM where SM is presently the greatest quality readily available. Try to find the “Energy Conserving” classification to optimize fuel economy.

Diesel Engine Oil Quality.

Usage oil meeting any of the following API performance categories: CF, CF-4, CG-4, CJ-4, ch-4, or ci-4 where CJ-4 is presently the greatest quality readily available. Making use of artificial oil is not advised during the warranty duration. The use of oil meeting API efficiency classification CF-4, CG-4, CH-4, or CI-4 while burning fuel with a sulfuric content higher than 0.5% or CJ-4, while burning fuel with a sulfuric content greater than 0.0015% is not suggested as oil service, is negatively affected.

Oil Viscosities.

Utilize the following chart to choose appropriate viscosity grades for the expected ambient temperature range.

Oil-Viscosity-resized.

NOTE: Multi-grade oils (such as SAE 15W-40) is recommended for year-round usage in Cummins liquid-cooled engines, or as a great all-season oil for air-cooled engines.

KEEP IN MIND: SAE-30 is the preferred summer season grade for optimal oil intake control in Cummins air-cooled engines.

Step Five: Gas Engine Fogging

If you own a gasoline-fueled RV generator it’s suggested to get rid of the stimulate plug and spray Onan’s OnaGard misting spray to lower rust and condensation in the cylinder.

Step 6: Inspect Connections.

Make certain all cable televisions, wires, and other connections are tight and safeguarded. You may need to tidy battery cable connections and lubricate linkage points.

Step 7: Disconnect The Running Battery.

It’s a good idea to detach the ground terminal to the alternator to get rid of any battery drain or unexpected rise back from your house system if the unit is plugged in for storage.

Onan also suggests running the alternator when a month for at least thirty minutes under 50% load to minimize the gas degeneration and varnish and keep the seals softened in the diesel and LP units. In some scenarios, this is not possible, so it’s important to take the necessary steps to clean, protect, and stabilize the fuel source to make certain your power cell performs well for many years to come.

Hey people, the onan 7000 generator is probably the most reliable machine in the market. With that being said I am having some issues with it and I need some help.

Prior to this the ATS would not constantly fire, and I delayed inspecting things as the reliable alternator was not urgently required (and I did not understand any better:-\ ). Now I am trying to nurse it back to health. I have actually cleaned it up, altered the oil, filter, air filter, plugs.

It now runs perfectly however it’s not sending power. Measured output at the machine reveals 1.2 volts using an Inova 3300 multimeter set for V 200 (unless I’m reading it wrong).

I’ve inspected the breakers at the generator power, absolutely nothing appears tripped in the coach – what’s next? I’ve checked out online about inspecting the brushes but I do not see anywhere to access them. Any concepts on what to check next?

I understand absolutely nothing about this high end generator but if you have a 110 volt receptacle on it, why can’t you simply plug a light or electric drill in it and attempt it.

I expect I might wire up a receptacle to among the output circuits and test that. That was a worry – that the 1.2 was really 120 at the incorrect scale – which would then cause an issue with the ats. I’ll head to House Depot tomorrow.

Here’s a link to an outstanding Generator Troubleshooting Guide put out by Flight Systems, a company that makes replacement voltage regulator and control panel (if you end up requiring one).

If you require one of those, they also make a nifty slip ring cleaning tool.

One big idea on the Onans – if they aren’t putting out A/C voltage the engine will stop as soon as you release the START switch. The control logic needs to see generator voltage and good oil pressure for the engine to stay following you release the switch.

The voltage sample is prior to the generator breaker( s) so make certain they’re completely on. Expand your search to the ATS input and see if there’s voltage there and if so, is the ATS working correctly?

Make certain your voltmeter is set to AC volts and not DC – otherwise you’ll get incorrect and probably really low readings on the output of the generator.

So I ended up taking the generator into a store to be looked at. If it had been sitting for a while un-used (it had), the tech asked. He drew out a 12 volt battery and ‘triggered’ it by connecting the battery causes the generator pos/neg wires (just a quick connection) – the generator started putting out 125 volts.

He said something to the impact that often the generator requirements are a quick ‘shock’ from the battery to get it to output power and in some cases it’s all that’s needed. Had anyone else ever seen that?

Onan 7000 generator Marquis not outputting power

Had to do this to the generators of my old Harleys when battery had actually been disconnected. At least you found a sincere store that didn’t offer a song and dance about something being incorrect and charging an arm and leg to repair you up.

I know you think you understand what you think I stated,.

But I am uncertain you understand what you heard is not what I meant.

I’ll be actually delighted if that’s all it is. Ran the Onan 7000 generator for about an hour up until now today, no concerns.
