A carpenter can figure out how to do anything
Don't ya love a challenge? I just bought a 21 foot RV without a generator. I checked inside the elecrical panel and it said that it needed an input of 7.8 amps. Quick check on the internet and it's only 110 watts per amp. So a little 1000 watt 2 ½ hp is all I need and I can pick one of those up for only $119.

Now for your brain teaser of the day.


All of the wires and fuel are there from the one they took out.

The generator has a generic side shaft motor with the pull start naturally facing out.

I love this site and I'm dying to see what your “square peg in a round hole, no problem” minds will come up with.

I had a 1000 watt gen and tryed it for my RV, and it was too small to even run the microwave. It worked good for TV, lights, and keeping the batteries charged. I had to go with a 4000 watt to run the AC.

Is there a air conditioner on the RV? If so, a 1000 watt unit will not be enough.

Need to ensure you consider things you will add to the RV in addition to it's onboard systems. How about a microwave, a coffee pot, etc.? If these, then 1000 watt unit will be hard pressed to supply the need.

I checked the electrical panel again
It does have a Power converter. It says Input: 7.8 amps 120 voltz 60 Hz. Output 45 amps then a space and VDC(with 3 amp battery charger).
Then is says 12 volt power block largest fuse 20 amps.

I used the amps to watts calculator on the Internet and it came out to 936 watts.

It has a refrigerator, microwave and hot water heater along with the plugs and lights.

The feed wire to the RV even has a 120 volt adapter on it.

Your right, there are hair dryers that take 1,000 watts, and I don't think they make a 12 volt microwave.

My 36 foot RV has (I think) an 8 hp generator on it. Somthings not right.

Time to ask a freind.

I'd still like to get your ideas on turning a pull start generator into an electric start though.

How about trying to fabricate a golf cart starter to the input shaft.

My RV has a 4000 watt generator on-board - it will run everything to include the one air conditioner. I sometimes use the RV from an external generator which will run everything (but major items such as microwave, coffee pot, etc. not at the same time) excepting the air conditioner - a 2000 watt unit.

The power inverter only carries the 12V load inside the RV. The rest of the equipment is 120V. Most RVs plug into a 30 or 50 amp receptacle. Lights, water pump, and exhaust fans are about the only things run off of the 12 volt system. Maybe the ignition for a gas water heater.
