Honda 2000EU assistance

How old is the unit ? ....

Thanks Wayne! If the rpm goes out of control, the problem may be with the microprocessor. I see a $ sign if this is the case.

For ninerbikes, thanks for the lesson concening the use of a heater with the honda gen. I merely used a 1500 W heater to put my gen under load and see what kind of RPM we are talking about. My gen in econo mode has a 3000RPM. The generator rarely went beyond 3600RPM under load. Today, it went to 4200 RPM. There is a problem!

The eu2000i's idle speed is 3,000 rpm with eco on and 4,300 rpm with eco off. Maximum engine speed is 5,000 rpm. On mine, with eco on, it hits 4,300 rpm at about 1,600 VA load. From fuzzy memory (i.e., don't count on it!), I think it begins lifting off of the eco on idle at about 400 VA. The rpm is controlled by a microprocessor, based I believe, on the DC input voltage to the inverter. If the alternator output were weak, that could explain the engine revving too high. On the other hand, if the output supports 1,600 VA for more than a few minutes, I'd conclude that the alternator is working just fine.

The info may be in the sticky at the top^^^^

"A small heater" is vague. How about the actual watt rating of said heater. The Honda is rated for 1600 Watts. By the time you reach 800 watts, the motor should be working a little bit and come up off of the RPM's that it runs while in "Eco" Mode.

Running an electric heater is a poor use of the Honda's electrical capabilities converting fuel to mechanical to electrical to thermal energy. Too may conversions with too many losses.

Use propane for heating instead.
