I bought a new Yamaha 2600 to replace my aging Honda EZ-2500. I have problems with it when charging batteries or using the microwave oven at my camp.
During the day I use one of the deep cycle batteries to power the out side stereo which consists of car stereo equipment including a Kenwood powered sub woofer, and a 400 watt Carver amplifier driving two speakers. By days end the battery needs a charge.
I had no problems charging the batteries with the honda. But the yamaha will not power the chargers properly. I only get a trickle instead of the full 10 amps from the charger unless I set it to the 50 amp boost. At the 50 amp setting I only get 10 amps for an output, and it is unregulated so I risk boiling the battery if I don't keep a carefull watch on it.
Secondly, the microwave oven takes longer to heat food. Yet resistive loads such as space heaters or electric frying pans including power tools and the TV / DVD and pump are not affected.
I brought the generator in to the dealer. Like nearly all dealers they tried to defend their product and gave me off the top answers saying that their readings indicated no problem. However after telling them about the low readings I got, including the fact that mehanical/electrical equipment doesn't lie- including batteries that are still low after hours of charging, got them to take the problem to Yamaha's head office for answers
Does anyone know what is happening here, or do I have a bad generator?
