Hi I have a GF1800E where the battery light stays on, I have 17 volts ac at the dyno leads when disconnected. Think I found the regulator/rectifier when I took the dash panel apart at the steering pedestal apart. would it be a box about 2 1/2 ins. square 3/4 in thick that has what look like cooling fins on the top. I have had problems with intermittent electric problems in the past. I have seen a place where a person could download or print manuals or diagrams from Kubota but I forgot where that was located. Dan
