I was given 2 keys with my pro turn.....
As far as a fuse is concerned I wouldn't be surprised if it's a wire hats worn through. There's a lot of extra wires just laying on the frame. Looks like they ate intended for upgrades for lights and such. Could be one of those.
been a while, Gravely sent me another key no problem. The fuse was blowing because the fuel solenoid wire was rubbing up against some sharp sheet metal piece.
