Hi, need to replace wy canadian 01WR426fn generator. Two quick questions 1- From the Yamaha website the YZ and WR don't seem to be the same. Is this right? (I assume they should not be because of the lights on the WR). 2- Is there a difference between the Canadian and US models? I remember those discussions about the blue and grey wire mods on the US model that we would not have to do on the canadian model... How will a US WR426 generator plug in my canadian wiring? Thanks for your help!
