Those hand written electrical diagrams are a nightmare waiting to happen LOL. Can't imagine trying to decipher and apply them.... Jesus. Zero electrical issues for me so that nightmare stays in check... for now. My hoses have all been very recently replaced everywhere with the exception of the 2 shower drains which are toast and leak. Next to impossible to change due to access. Aft shower was doable relatively easy. Forward shower, after cutting the corner of the floor out in the generator room to try gaining access to the drain and hose end, theres just no way to get under the shower to the hose end from there. Maybe cutting some of the wall out might give access to it but even then, not sure it would be enough. Its really tight right there with the fuel tank. Hose looks healthy enough to leave that first foot on anyway and go new from there to the pump so thats how its getting done. And Carleton, if you're looking for any docs let me know. More than glad to send pics of anything I have. I have all the OEM docs !
