Yamaha 2000 problems

[Welder99]

Hello all, to begin with I purched 2 Yamaha 2000 generators used very little. They came with the wire kits to hook two together . I powered both up at high rpm then turned on my AC . One generator revved up and would not power the AC . I didn't have the generators on power saver mode. They were both at high rpm at the time I turned on the AC. One generator went to yet a higher RPM. I also have a Honda EU 3000 that I hooked up and it had no problem running the AC. I used my volt meter and it showed 124.7 volts at the hook up kit. So I'm confused as to why they wouldn't power the AC . Also I have the soft start capacitor on the AC. Any input would be helpful. Thanks.

I've been having problems with my 2 Yamaha 2000s also.
One of them, the same one every time will go into overload and then the a.c. shuts down.

I'm seriously considering even though the trailer is new getting a high efficiency A.C.

Have you checked the oil in the one that will not rev up? If it doesn't have sufficient oil, it will only run at ECO RPM. At least that is the way mine works.

I also had trouble when mine were on an uneven surface.

It's too easy to get fooled because of measuring voltage from the generator not in circuit. Measure voltage at both generators.

It sounds like something isn't right with the daisy chain wire kit. It sounds like only one generator was trying to carry the load since the other one was not increasing its RPMs.

You can / will get 124.7V off of one generator or both, but it sounds like only one was putting power into the wiring harness and therefore you were only getting the 2000 watts from one generator, not the combined wattage needed to power the AC.
