pressure1 died. Fuse was blown on the aux aux2 power port (didn't note which one - will check) of downwind1. Replaced it with a 1.5 A.
Also replaced the aux1 fuse on the downwind1 box. Had to break it to remove it - it was frozen in its bed. aux1 port still doesn't work.
upwind's usbdisk was not mounting. Replaced it.
