hi, the regulator failure's a bit of a bummer, but not a hard one to sort out. mine did not fail, i just did not want to left stranded with a flat battery and an edc light on!

about 20,000 miles ago i replaced mine with a more suitable unit off a yamaha fazer 600, secondhand on ebay i gave �14 all in.

it has 5 wires; black, red & 3 whites. cut off the inferior connector and connect with corresponding colours, the whites [generator phases] are non specific to the regulator [any order]. now my connector probably is the weak link, perhaps in the future i will hard wire to the loom, soldering & heat shrinking to create a perfect join. if a failure happens just resolder and seal

because the 'new' reg has about 8'' of loom it's easy to point the wires down to stop any water ingress, secure the loom out of harms way. the reg needs a slight adjustment to align the holes, better to ream out the mounting plate wih a drill etc and jobs done. now start the bike, check the battery voltage, should be above 13v with a voltmeter. any probs give me a shout.
