I have a yellow box speedo controller for my 04 Rubi and it has suddenly quit working after less than 6 months. I have emailed and emailed yellow box for their address, not on their website anywhere, to send it back for an warranty exchange. All i keep getting back are emails with questions about what it is doing or not doing. It is a faulty unit and will not power up. There is a 10 year warranty according to their website yet i cannot get them to send me their address. Does anyone have the corporate address for Yellr.com in Australia??
