EDIT ADDED 45/5/2013- When this thread started in March of 2005, I never expected to see it survive this long or amass the quantity of information that has been shared here.

In the eight year run of this thread we have amassed almost 10,000 postings and surpassed a million views. This creates somewhat of a dilemma for anyone who has just discovered the forum.

Since the amount of information is virtually overwhelming, I suggest you set your preferences for this thread to read "newest first" and then begin to page backwards.

What you will find in these pages is a wealth of info on virtually any make or model of Chinese manufactured synchronous (non-inverter) generator in the 3,000 watt performance class. Info will include how to rewire series coils to parallel to obtain maximum wattage from a single 120 volt outlet. Tips on further reducing sound levels, how to care for these generators, which ones are "RV ready" and provide the best overall performance for the dollar invested. Which companies NOT to deal with, where the best prices are, how to safely wire the generator into a home or RV, how to check your RV for electrical faults, sources for generator accessories, which 20/30 adapters are safe to use and which are not. How to convert a gasoline generator to propane or NG. This is only the beginning. The forum has a life of its own with the focus sub-topic switching frequently. Still, the main topic of utilizing the amazing, inexpensive Chinese gensets is always there. The amount of creativity and innovation presented in these pages is indicative of the talents shared in the diverse backgrounds of the folks who make up our combined RV community.

Many of the original brands and models of Chinese gensets mentioned in the introduction and early pages of the thread have since disappeared. New EPA and CARB emissions requirements, company bonds assuring the emissions warranty will be honored even if the company goes out of business, and fierce competition in the industry have changed the playing field. Champion Power Equipment has become the apparent "trophy team" providing an ever expanding retail outlet, an ample parts supply, a strong warranty and excellent customer service. CPE has continued to improve their product and now offers a new model (#46538) with exclusive convenience, safety and performance features aimed at the RV market. Big names like Cummins/Onan, Honda and Generac all now have Chinese built open frame synchronous gensets available. Ironically, the prices often found on these gensets has not significantly changed during the past eight years - even with the devaluation of the American Dollar and new EPA/CARB requirements.

I also encourage you to use the search function and even the advanced search options to find information. Key works such as "rewiring", "PowerPro", "Champion", "Onan Homesite", "Duropower", "ETQ", "Jiung Dong or JD", "Tractor Supply", "Costco", "Lowe's" and "Home Depot" are all examples of keywords that will give you specific information on different models being sold by retailers today.

Or, you can fill your glass with your favorite beverage (keep more close by - maybe some munchies as well :D, sit back at your computer, tell your wife (or significant other) that you will see her in the morning and spend the next 10 or so hours reading through the postings.

No one on the forum gets mad if you ask a question that is a repeat. Please do not hesitate to post to the forum. All questions are considered important and those active on the forum will do their best to respond with a valid answer.

Also note we are not out to knock the Honda, Yamaha, Kipor or other brands of high end digital gensets. We recognize the quality of these products and their suitability for quite, efficient RV use. But, there is a flood of reliable, inexpensive and comparatively lower cost gensets coming out of China that are excellent alternative choices for the RVer wanting power to run an air conditioner, microwave, etc. without excessive noise or breaking the budget.

Oh, one last thing. The folks on this forum are true gentlemen. We do not flame one another or the product discussed - period. Ugly contributors usually have their comments and remarks ignored by our masses. It is not a forum to start arguments to obtain a clear win. We do disagree on many issues, but we have all agreed to do that in a respectable manner.

We now have the introduction of more and more inverter gensets. There is a rather extensive thread named "The Official Unofficial Champion 2000i Generator" on this forum. Today, I added info on the new Champion 3100i inverter genset. Discussion on this product may get moved to its own thread at a later date.

Many have looked upon this thread with distain saying Chinese is cheap and doomed to failure. I remember saying exactly the same thing about Japanese products a few decades back. But, over the past eight years the track record for Chinese built generators has shown otherwise.

Please, join us in a fascinating journey down the Chinese built genset road of knowledge.

This is the question I posted that got it all started back in March 2005.......

For a little over a month now, I have been somewhat intrigued by the availability of a 3000 watt, 6.5 HP generator at Pep Boys and Northern Tool for under $300.00. The engine on this generator looks identical to a Honda 6.5 HP OHV engine. Knowing that the Chinese have become very adept at โ€œcloningโ€ reputable technologies from other manufacturers, I was not surprised at the similarities. Neither store could give me any information on the generator nor did they have a โ€œrunningโ€ display model.

I have done a little research. This is what I have discovered:

Many of these generators are imported by ELIM International (www.eliminternational.com) out of Buffalo, New York from Jiung Manufacturing in China. (The unit at Northern is identical but carries the JIUNG name.)

The engines are indeed a Chinese knockoff of the popular 6.5 HP 196cc Honda Engine. โ€œSupposedlyโ€ Honda has licensed the engine technology to the Chinese manufacturer of the product.

The Chinese company that makes the ELM3000 generators is a rather large, diverse, long-standing company with a reputation for โ€œabove average qualityโ€ Chinese made products (Jiung Manufacturing). There are many more Chinese companies making almost identical gensets.

The generators at PepBoys do have a six month limited warranty. But, it is only on the engine (not the generator) and requires paying for shipping to and from Buffalo. Probably not a very practical thing to do if you have warranty issues.

ELIM does supply replacement parts (a PDF parts manual is available on the ELIM web site). No prices are given for replacement parts nor is there an โ€œavailability listingโ€.

The generator head itself is a brushless design. The only really significant wear parts in the generator are the bearings โ€“ most likely universally available.

The published dB rating is 67 at 23 feet. This is โ€œreasonablyโ€ quite for a generator of this size as most comparabl.... The 67 dB rating is the same as Honda gives their 3000 watt CycloInverter with a โ€œlook alikeโ€ eng...

OK. New scenario. Say I just wanted to install a 30 amp plug in a box onto the side of my generator. As long as I use big enough wires, can I just use the following diagram and hook up a new outlet? this way the genny stays the same and I get a new outlet. I know that I will need to run the genny in 240 mode, but I'll only be using 120.


NO don't do it that way, don't run in 220 mode, that will split the windings and give you have POWER/amps on the outlet because you will only be using ONE winding

jumper the wires from the duplex connections to the new RV outlet and leave it in the 120 mode, you will get the full 25 amps.

you can remove the 220 outlet, capp the wires( do not use them ) replace with the RV outlet, and jumper the wires from the duplex to the new outlet


I have a metal bolt on box and receptacle. now when you say jump from the duplex, do you mean( according to the photo) the red wire to one plug. The blue to the other. Then ground to ground. Does this mean that one of the hot wires act as a neutral?

From what I can see on the wiring diagram, I have to agree. The external RV connector in a bolt-on box is a good idea, however. If you ever think you'll want to have 240 VAC in the future, keep the 240-volt socket as it is. Instead, just run the wires on your add-on RV box to the back of the existing 120 volt socket connecting that pair of sockets in parallel with the add-on RV socket.

Keep in mind that I still haven't tested my Power Pro with more than 15 amps yet, but I can't see why you wouldn't have a full 28 amps available to your RV socket with that kind of hookup.

Scroll down toward the bottom of the page. The original post seems to have disappeared, but you don't need to remove the starter first, remove the starter and housing as a unit.


Did mine today. Here are a few pics.

Approximate location of the starter and housing unit bolts are here. (Pic wasn't taken at the right angle to actually show you all of the bolts, but they're pretty obvious.)


Next comes the flywheel nut. This is 19mm, or a 3/4" socket fits, also. I used an air wrench to bump it off. Putting it back on, I stuck a big screwdriver through the holes on that silver thing so I could apply some torque.


Here's a pic of the exposed flywheel. I drew in the places where I put the sealant.


I used threadlocker on the nuts and bolts when I put it back together. I'll know tomorrow after it cures whether it helped with the sound or not.

You are very observant, maybe you can be the first one to install it on a Champ.
Do some of these look-a-like Chinese units have the electric starter as a option? If so, it would be snap to install the remote electronics.

The tab between the outlets is in place and on the red and blue wires going to it. What does this tell you?
does this help any?



Edited to reduce picture width - Mel


It just looks like it is wired they way the wiring diagram says it is supposed to be wired. Well, it is if you assume that you are looking at the rear of the sockets in the wiring diagram. I also assume the little T-shaped slots in the 120V receptacle are on the bottom of the socket when the panel is reassembled--like it is on mine.

I would agree with you. I put it on this thread to be a mind teaser to some, but with the activity on this thread, I hope to see someone DIY on a Champion style generator.

I may have to buy one myself just to expirment.

You said that the genny struggled but was it able to keep A/C running for you? We bought the Champion to run our A/C when we are up in East Zion during the summer and the elevation there is right at 7,000 ft. The nights get down into the low 40's, even during the summertime but gets up to the 90's during the day. As long as we can get the A/C running, we'll be happy. We will be testing it out this weekend.


I typically camp at right around 7,000 and have had no problems whatsoever. But at 8,000, things changed enough for me to take note. I had to use Mr. Wizard's method of running the fan only for about 5 minutes or the A/C would not have started up. Period. And keep in mind that the A/C and microwave simultaneously at anywhere near that altitude is out of the question. At least it is for me.

I am waiting for a response from CPE on the availability of high altitude carb jet options. I will post their reply if anyone is interested.

This is a mod for someone that has a little extra time on their hands. It will make your wife happy and you will not have to get out of bed to start your generator. She can even start the generator.
the 13 sec video

The starter is cheap Briggs and the remote is a 4 function Chinese made.
The remote is good for about 100'


Please post more details. What briggs starter parts are needed? What did they cost? Name and cost of the remote starter module? Do you have pics of the installation to share? Etc, etc, etc.


Bob,
I will try this weekend to do a short write up with links and pics


Note, I will be gone for a while and will not be able to post anything more for about 2 wks.
This is the way it works, I think maybe you can adapt it to the Chinese generators. It would take some effort, but I am amazed at the mods that have already been posted.

I will give the basic method that I used. I think that this will work on any of the small Kipor or even the ever popular Champion. The remote control and receiver of course would work well on the 3kw and up that have a battery and starter system. Hays equipment sells a remote control system, but it is really pricey.
Let me preface this by stating that this self-start mod work very well. The starter takes it power from the RV battery. I suppose that a dry type battery could provide the starting power if desired. That battery could also recharged from the Honda 12 volt source. The starter motor is coupled to a 1" diameter spool (used a ยฝ pvc plastic pipe coupling) and when activated, the motor simply winds the rope around the spool. Just before the rope reaches the end of its mechanical travel, a normally open switch closes and opens the start circuit, cutting the power to the starter. The Honda rewind spring then rewinds the rope and the cycle is complete.
The starter is mounted on a 16 gauge aircraft (hardened) aluminum plate that I hand bent to fit the profile of the Honda. It is not fancy and steel could be substituted. The plate is held onto the generator by 4 strips of 3M high strength Velcro. I chose Velcro for several reasons. First, it's easy to remove, it also serves as a spacer to stand out the plate from the generator so screw heads and other hardware can be placed on the inside and mar the generator case. I used 2 #10 machine screws to secure the starter plate to the aluminum mount plate. I did use 2 #6 self tapping screws just to make sure that it did not fall off while traveling.

List of parts and materials
โ€ข Starter can be almost any small engine, The best and easiest to use would be an old Brigg that uses wound fields instead of permanent magnets. This is important and I will explain this later with more detail. Briggs are the most common and can be purchased on Ebay cheaply from $15 used to $50 for new ones.
โ€ข A horn relay for the heavy current to the motor. A NTE R51-1070-12F SPST 70A about $8 or other equivalent, make sure the coil does draw more than 1/4 amp.
โ€ข A momentary 4 function remote and receiver from china. Cost under $20. The momentary remote receiver will need a couple of circuit mods for it to work properly.
โ€ข I used about 6' of stranded cat 5 for the wiring between the remote receiver and the generator.
โ€ข A few dollars of misc hardware.

The next are optional for choke and unchoke operation.
โ€ข A model airplane servo for the choke control if you want to have a choke control. About $15 for a cheap one.
โ€ข A servo control circuit. I suggest using one of the many 555 timer chip circuits and setting a fixed resistance for choke and unchoke.

Just a couple of observations after a trip to YP:

1) At 8,000 feet above sea level, the Champ starts to struggle a little bit with the A/C. I should probably see about rejetting the carb.

2) Unless the one next to me was very broken in some unobvious way, a Honda EU is hardly quieter than the champ with the Eco-Throttle off. It served as my 8:00 wake-up call. I will admit that with no load and Eco on, they are whisper quiet.

Carry on.

I started to take it apart today but stopped at the flywheel nut. How much pressure is needed to remove this nut? Its on there pretty tight and dont want to force it and break something. Any tips on getting it off easily?


Nevermind. Got out my impact driver and the bolt zipped right off. Put on the RTV and now letting it dry. Can't wait to fire her back up to see if there is any change. Thanks again for all those who have added to this thread. What a great wealth of info!
