charging system fault

Sorry to be so needy, but when you say read "between" any of the terminals, does that mean I am putting the red lead from the multimeter on one of the terminals and ground the other lead?
 
If you are confident in your measurement, then yes, the stator is good and can be eliminated from contention.
Therefor that essentially leaves the Regulator.
(you cannot effectively bench-check a MOSFET SHUNT Regulator)



It is really not necessary to buy an OEM R/R - it can be replaced with a genuine Shindengen FH012 or FH020 Form/Fit replacement commonly used on Yamahas and commonly available both new & used on the Internet (just DON'T get one that is cheap Chinese copy of the same - those look similar but you'll know predominantly by the price)

Better is a Series Type Regulator - Shindengen model SH847 - do a search on this forum for details of that device and installation information.

I replaced my OEM with a Shindengen, per Decosse's recommendation back in 2011 on my Datyona 955i. No issues since :p Thanks Ken.
 
Black or red does not matter which one goes where on a resistance test! And yes one lead to ground and one to a terminal in connector.

I believe that's the same one I've just installed...fully charged the battery, installed new RR rode 30km @80 - 120 km/h stopped, sat for 9hrs the did the same trip home. Bike wouldn't start the next morning and showed 9.5v
 
So open circuit on all 3 stator legs and a new RR and it's still not charging?!

Going to defer to the big brain on this one, Ken. I would have expected it to be charging at this point!
 
Initially i replaced the battery so I'd hope we can rule that out as a dud. I'll do the open circuit stator test tonight.

The only clue for me to follow on with is the black connector on the new rr only having a left and right pin when yhe oem rr has a centre pin as well
 
The stator or R/R is going to be one of those 95% of the time
Do check the connectors, ensure there is no burning on them and that they are fully engaged & clicked into place.
On Kevin's Touring the ground pigtail connector was burned, so check that - it's about 6" from the battery terminal on the smaller gauge wire.

Can you confirm what R/R you installed? There are a lot of shindengen fakes out there ......

At least in your last couple of posts (havent searched further back) @mr hunt I didnt see whether you had done the stator check above

Dont worry about number of pins - pretty sure your OEM harness doesnt have three wires on black connector so centre pin question is moot

Thanks Ken no i haven't done the stator check yet...will get to that tonight .... i have new apprentice to train...
