ok yea my rectifier can only plug in one way its got a 6 pin white flat plug and the wireing coming from the stator has 2 sets 1 has a flat white plug 6pin n that go's to bikes wireing harness the other has a square green plug with 6 wires but carnt find a place for it n mymy67xr seems to think it might have been for a gear change indicator n suggested I just secure it on the frame some where n I think he right as it comes from a round black plastic piece going into the l/h crank case just under the gear selector shaft n it runs fine without it n when I check the voltage n if the rec no good I got a brand new unit n about 6 s/h ones so that will be no probs cheers
