did you ever check all of the fuses? just to be sure...follow the wiring from stator to the battery...emiminate as many other possible faults before investing in parts...

:hello: and :welcome: to :660:

Yeah I checked fuses. Cheers for reply 👍

Have you checked the old system at 5k rev's?..is your old battery holding a charge?..what did the vendor say about the issue?..

To be honest I�m not sure it was 5k revs when I tested old system, I just revved it a few times and the volt meter didn�t rise. Both batteries are new so I�m assuming they are ok . I�ve been in touch with the ( private) seller who has sent me a stator. Cheers Barney

ok..are you planning on trying the old stator test?..ie hold revs at 5k and test for voltage increase..

I would have thought your reg/recifier could be the issue tbh..

+1 on the rectifier failing, especially if your headlight bulb has blown and you haven't noticed that yet.

Think it is the regulator/ rectifier lads. Fitted different stator and no change. Any body got one for sale?

Have tested the current one??(no pun intended).

Get the part numbers and do an ebay search..a few on second hand and a lot new.

Upon reading your post it reminded me of previous hondas I have owned and their tendency to lunch a rectifier so I also had a look with the idea of getting a spare,just in case. I've a 2011 xtz and it looks the same as the xtz/xtr one which also looks the same as other yamaha model, like the r6 and r1, but is listed on ebay sightly differently, looks like wider pins.

Think I'll take a punt on one of these and test it upon arrival.
