    My Onan 7000 will not run both A/C units without serging, rpm goes up and down continually. The unit was fine last use about a month ago but now has developed this problem. Any ideas would help.

    when was the last time it was serviced???
    The way it sounds is that the governer may be sticking or u may have a lean fuel condition,, imo i would ck all the filters and ck to make sure u have enough air flow to the unit.. i would also ck the fuel ,, u may have a bad batch,, does it do it with only one a/c running and all other ac appliances running or just with the 2 a/c units,,, ????
