The normal sequence for the K2 relay is a GROUND signal from the Oil pressure switch. NOT a 12 volt positive signal. There should be 12 volts on 1 terminal of the K2 relay. If NOT, then either a wire is loose or one of the fuses on the Genset is blown. OR the K2 relay is bad. The signal from the Oil pressure switch is indeed a safe to run signal. Your problem is a common oil sensor problem when "it runs when the button is pushed and held, but stops when released". OR you could have a bad oil pump,(not likely). All you have to do is GROUND the wire connected to the oil pressure switch. If the engine stays running and you DO have oil pressure, it is a bad oil pressure switch. Doug
