So the bucket stopped moving. After some time of frustration and searching forums I found that it could be a fuse. The fuse for switched attachments. Replaced it and it worked fine. After two weeks it blew again. When i tried to replace it the second time, it blew at contact. So i'm guessing there is a constant short somewhere. I followed a huge bundle of wires coming from the fuse box, but couldn't find any visible wire damages or shorts. Do you guys have an idea what and where the problem is? Thanks in advance.
