If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits. - Навчання та стиль
Thank you... you rarely see a sine wave test on generators... I have the previous model of that generator a d love it... maintain it and it will last for thousands of hours... I think I have 1600 on mine now... thanks again for the video...
Welcome

I just had a problem with my generator not running my ECM motor in a gas furnace. I was getting 120 and 24 volts speed signal but motor wouldn’t run. After double checking my equipment grounds and a phone call. I tried loading up the generator instead of only running the furnace on it and it worked great. The generators tend to chop off a sine wave at around 120 but produces much higher peak to peak voltage and the ECM motors just don’t like it. So if your have that issue try loading up the generator and drag that peak to peak voltage down. At least it worked for me.
Good info.

Buffao Corp makes sportsman generators. They have inverter generators. Check them out. These folks are great with customer service.
I bought that same Genni years ago and run almost everything in the house for years when the power goes down... Never skipped a beat.. I never ran mine on gasoline .. never will with the garbage gas they are making now a days..
Great Video. If possible could you make video how to connect electric wire from generator to electric wire house for power whole house . When house lost power . Thank you for sharing ^_^
It would be interesting to see the same test but with your power saver capacitor plugged in. Wondering if it would clean up the ripple.
I know it makes no difference but I will do one with it connected along with some other devices.

Love your vids I've been a big fan for a while. just wondering if it would be safe to run an 80% furnace on a regular generator or do you need a inverter generator so you don't fry the board?
I think the inverter generators are best. Less chance of a mismatch.
GFM
@@grayfurnaceman ok thanks for getting back to me. Have a great day!
I wondered if you could tell me what size the tubing frame is on that generator? There is a wheel kit that fits it, and I think it would fit my different model generator depending on the tubing size. It looks to be about 7/8" or 1" maybe???
It is 7/8" od.
GFM
@@grayfurnaceman Thanks a lot, then it should fit a LOT of generators out there, including mine! Great to know
I know im late to the party here but im looking at buying this same generator for emergency use. Thanks for the load test. Would this be a dependable generator to keep for just in case scenarios, or is it difficult to start if left stored for a bit? I would definitely start it once in a while to let it run but i may never actually need it so im curious how it does if stored for a bit. And has anyone maxxed one out to see how much it could handle before its overloaded?
You can store it for 6 months or more if you keep ethinol free gas in it plus run the carb empty Everytime your done using it.
Thanks for the video! We’re about to buy this generator and we’re wondering if it would handle two 500 watt deep freezers and a full-sized refrigerator (about 800 watts).
I’m not too familiar with generators so any response would be helpful and appreciated. Thank you!
Is it clean enough to power a refrigerator or a small heater?
The heater should be fine. Motors are a bit different. Some work perfectly, but some will overheat and shut down. Electronics that use microprocessors do not seem to work well.
GFM
Thank you for the info brother.

That's a big...load
Is There a Generator That Produce a Pure Sine wave?
You can use an inverter generator. They tend to have a much cleaner sine wave.
GFM
inverter generators use an electronic oscillator to produce a pure sine wave, they're as clean as you can get. you'll pay 3 times the price for an inverter model though.
@@embeddedgirl They do. That is the only way to get that good sine wave.
GFM
Clean enough for a microwave
A lot of newer appliances have digital readouts ,circuit boards and the like , I would not want to run something that has a uneven power supply with power spikes that could destroy a mother board , some of those computer boards are a couple hundred dollars , better to get a inverter generator if you have expensive newer appliances with a lot of new technology,
I would generally agree, but there is more danger with destroying motors than electronics.
GFM
@@grayfurnaceman I would think electronics would get destroyed first, because when computer people are working on circuit boards they are always concerned about even small static shocks such as we get from walking on carpeting being enough to blow the tiny components , as opposed to a motor that had thick copper windings that should be able to absorb a brief power surge , I could be totally wrong, but that is just my thoughts on it,
@@bluemouse5039 I would have thought so too, but computers run on DC power so their power supply eliminates most spikes. Motors, on the other hand sometimes overheat from the unsteady side wave.
GFM
@@grayfurnaceman Thanks, that good to know,
If you want clean power you would buy a inverter generator.
You got it.

I ran My computer & Big screen monitor AND PS3 and small window unit on a colman gas genorator with no issues at all.
@@scootscoot97warlock90 I've run a computer and a 65" tv on my DeVilbiss brushless gen. set as well. It doesn't mean that the power is clean. Harmonic distortion can cause damage, and undue wear and tear on electronics. It is what it is. A brushed gen. set is a bit better usually. Your Coleman, at least the ones I've torn apart are usually brushed units. Probably around 15%-20ish.% THD. As for brushed I would say 20ish. +. It also depends on how much power is demanded on the gen set.
5% or less is considered safe for electrinics. It also depends though on how well the power supply was built in the device used on how well it can clean up the final power needed to run the device. Easy Peasy. As I said it is what it is.
@@NY411Info I do remember, I made sure not to load the generator hardly at all. It was a 6500 & I was probably drawing 2300ish watts,if that matters. Maybe I just got lucky
