If you tested all three of the yellow wires from the stator and get about 70 volts AC on each one, then that should tell you it's not the problem. There are plenty of YouTube videos on testing a R/R with a multimeter, but assuming your stator is good, then it pretty much has to be the issue.

If you're going to replace it, I'd recommend switching to a series style one like the shindengen sh775. Keeps the heat down and should prolong the life of the stator.

Thanks for the reply. A couple of questions remain for me.
Why would it test fine when unplugged from the rectifier yet not OK when plugged?
Also can I damage my new stator by running the bike with the faulty rectifier?

I suppose what I’d like to let people know is that testing the wires from the stator to the rectifier whilst they are connected up, produces a different reading to the wires when they are not connected!
Mine read fine when not connected - up to 70v AC with revs.
Connected I get low voltage with no increase with revs.
All that I’ve read does not say “test whilst disconnected” so a stator replacement mightn’t be required if low voltage is shown when testing the 3 wires when they are still connected to the rectifier.
