Genset will start when hold up start switch, as soon as it starts and I let go of switch it shuts off. Checked all SS's and good. There is a wire that has a male and female connector on the lower right front of the unit under the propeller unit by the belt. I separated it at the connections and the genset started and continues to run good powering the entire boat. But with the wire separated I can't shut the unit off with the switch on the unit or with the one in the boat. To stop the genset all I have to do is touch the two separated wires back together and it shuts down. Not sure where or what the wire goes to at this point. Help, any ideas as to what the issue is or what I should do?
