My Cummins Onan Model 6MDKBJ-1100A genset is throwing out a code 27 and I think I have either a bad circuit board or a bad stator. I have a good local certified Onan mechanic, but what is the best way to access the circuit board and stator on a 2014 Sense 50'? They are both in the aft part (left side when facing the front panel) of the white genset enclosure, but there is not enough room in the Genset compartment to get proper access. And pulling the whole GenSet unit from boat will be difficult.
