I have no idea what I did today but I spent a couple of hours doing it. I realized there were more ground wires that needed attachment, but I'd already mounted the fuse box. I didn't have any metric wrenches -- the Rotax is made in Austria -- and I didn't want to unfasten four bolts, so I went to the hardware store and bought a $55 metric wrench set only to find out the nuts are 7 mm. The wrench set only comes with a 6 or an 8. Waste. So I took the fuse box office, added the ground wires. Then added the sealing washers to the Lane A and Lane B connectors and routed the wires and secured them to the fuse box. Then I added two generator wires. I'm digging this plug and play stuff. I dug out the ECI -- the Engine Controller Somethingsomething -- to figure out where it goes (under the top skin so I took the top skin off and drilled the four holes out to #12. I'd left the dogs in the house unattended so I figured that's enough work and went home to mow the lawn and see if there was any damage inside the house. There wasn't. Good dogs.
