I'm working on a JD 350DLC excavator that I just finished replacing the engine head on. The problem I'm having is that it won't crank with the key. I can start it at the starter and at he starter relay by jumping from batter to relay terminal going to starter. Does anyone have a electrical schematic for this unit or a whole tech manual. I have checked all fuses in the cab behind the seat the three fuses at the starter relay. The machine started fine before the engine repair. The S/N FF350DX803299
