When I bought this unit the generator had to be hotwire to the fuel shutoff for it to run. In troubleshooting it I discovered a blown relay, Replaced both relays and ended up replacing the circuit board due to a loose terminal. These problems are apparently the result of a bigger problem as I still can not get the remote start switches in the unit to work. I took a picture of all the wiring before I started and have traced them out on the schematic, even made a copy and colored the wiring to ensure the correct routes. Theres not much left that I see other than maybe the regulator. I did get it to turn over from one remote switch, but the shut off solenoid never moved.
