I have an Onan 7500 watt diesel generator.
With nothing on in the motor home, other then then items like the CO2 detector, the Microwave display, etc etc. the following is happening.
The generator will run at three different rpms (judging from the sound) At each level it will run for several minutes (5-10) then will switch to the next level. Kinda like shifting gears.
Inside the motor home I have a Xantrex display that shows DC Volts, amps and Battery State.
The Battery State displays 3 different battery levels. First indicator is an outline of a battery and shows a low level, next little battery shows a 1/2 level and the 3rd battery display shows a full battery.
When the generator changes rpm (power) the Battery State display will change also.
I don't recall my generator doing this before.
I did check the voltage at the batteries at they were all good.
Any ideas?
Thanks
Brian
