Hmmm,

New Champions all over the place. I live not far from pplmotorhomes.com in Houston. At one time they sold the Champion 40008 NOW they sell the new UltraGen by CHAMPION (Blue)that is Electric Start (looks just like the 40008) @ $630.90 plus shipping. Makes the 3500w Electric Start DP3500EC by DuroPower @ 349 and Free Shipping with side and end panels (63 bBA) almost 1/2 price or two-fer one.

As the old saying goes, “they made a mistake and wired it just like the print” which they did. The windings are connected internally. I removed the generator cover where it exposed the terminal block. Then disconnected the wires and check for continuity. Tracing the wires further they go into the winding. It would have been so easy if they had made the connection on the terminal block. Like I said in an earlier post. I made up a 10-4 cord and have the 220 volt plug wired to a 50 amp receptacle that I can plug the fifth wheel into. The generator came with 12 amp breakers and when the A/C would kick on it would trip that circuit. I replaced the two 12 amps with 15 amp Square D breakers and now the 13,500 btu A/C will run and not trip the breakers. The breaker that feeds the A/C also feeds the microwave. I know I won’t be able to run the micro while the A/C is on. The other side of the circuit feeds the rest of the RV. I just hope the windings on the A/C side of the generator hold up. Once the A/C starts and is running it should be below even 12 amp. I would check it with my amp meter, but the batteries for it are dead. I would like to thank you for your response and your contribution to this thread.
Thank you.

The generator is un-grounded and it reads approximately 58 volts to ground from both the hot and neutral even when it’s plugged into the RV. Is that okay? I’m thinking it is

I just got an ad in the mail from Tractor Supply. They have the Champion for $299 with a free $50 gift card (mail-in). From the picture, it looks like the RV 3500 watt model.

OK... I am back on my generator project after having to take a month or so to deal with some other projects, including painting, motorcyle engine rebuilds, etc...

(too many projects, too little time)

I am very satisfied with my duropower generator and I have what I believe is a "workable" solution to using the exising fuel line from my RV. When I say "workable", what I mean is that I have setup the generator on my bench, inside my constructed box, and I am supplying fuel from a single fuel line with a fuel pump. My generator ran for 5 straight hours in my testing. I do not plan to set up the return fuel line so long as my solution works.

I am working on sound issues since the chinese generator at 3600 rpm idle, generates more vibration than the Onan. That vibration turns to noise.

I have acquired all necessary stuff to build a new box, which will include a wood frame, mdf panels, fan, sound baffle on top, lined with some dense carpeting that are basically scraps from the local carpet store. I am tempted to try the 2 inch foam panels, but I am not sure how I would mount the carpet to it.

My question today is... I need to wire this generator into my RV. Below is the wiring diagram for the duropower 4500. I am not exactly sure where I am supposed to tap into the power. My old generator was an onan 4K. Can I simply tap into the L5-30r receptacle and hardwire it to the electrical panel in the RV.

this is where my knowledge falls a little short. Any help is appreciated.

Reresh my memory. Is your RV a 30 or 50 amp?

On the schematic there are two circuit protectors at the top with no rating. Do you know their value? The one going to the duplex outlet is marked 20 Amps, but the others are not marked.

With the MDF I doubt that you will need the carpet. If you do use it, you can just nail with roofing nails or staple it on. A good glue is 3M High Strength 90. It is in a large spray can and I find it with the rest of the glues in the paint section of Lowe's. 3M 88 also works but the 77 will not hold its bond with carpet in a hot cabinet.

Let me know what power rating your RV along with the unmarked CBs on your Duropower are and I will try to help you on the hookup.

BTW - your fuel line/fuel pump scare me. Honest, while it may "work" it is not safe for the design of the carburetor on your generator engine. It is not a question of "if" it will leak, it is a question of "when". Think about it, is it really worth the risk? I have been know to be wrong, but I am right on more things than wrong things. I believe my caution is one of the right things.
