Bobcat 225G Plus - Serial # KG052667 - Onan P16 Gas Engine. I finally have the slow and fast idle set right (or close to it). Engine will not come up to weld speed when an electrical load is put on the Aux A/C receptacles or when I try to weld. It never leaves slow idle unless I turn the switch to "rabbit". Owner's manual says: "Have factory authorized service technician check the auto idle module PC1 and current transformer CT1".

Is there a process I can follow to check PC1 and CT1 myself, without taking it to a shop?

Any other suggested solutions to this problem?

Thanks JA.
