I have a generac 7000 which suddenly produces no power. The idle control does not seem to be working as well. Ordinarily the generator only idles up when the power is being used. Now it neither generates power or idles down. It seems that the problem I'm having affects both the idle control and its ability to generate power. On the 120 volt side it only produces 4 volts and on the 240 volt side it only produces 8 volts. Can anyone help me on this?
