Onan generator cycles
I have an Onan 5500 generator. As I was exercising it today it constantly cycled. The only load on it was the electric fire place and possibly the converter. When I have exercised it before, the generator would increase in rpm when a load was initiated, then would settle down and run at constant rpm. I shut the fire place off and turned on a space heater with the same result. When the rpm decreases the voltage drops to about 106. At the higher rpm voltage is about 118. With no load it runs at a constant rpm and voltage measures 118. I have run 2 ac units previously when exercising with no problems. The fuel tank is about 5/8 full with premium gas and stabilized in July. I have been exercising it once or twice a month during that time. Can anyone give me some insight into what could be causing this?
