Don't believe it's the battery, Rich ......

Sounds definitely like either R/R or Stator failure - although sometimes can be as simple as the stator connector burned, which is not uncommon.
One way or another those voltages while running indicate at least one phase is down.

I personally would recommend against re-installing another OEM type SCR R/R - the FH008 Honda units are good choice for the Triumph Twins with the connectors reworked accordingly.


I just read your cutting out issue again - not the side-stand switch. The side-stand switch only comes into play when the bike is in gear; if in neutral it should have no effect, up or down. However since raising the sidestand 'fixes' the issue, it actually points to the neutral switch being the culprit. Can you by chance see you Neutral light go out when the issue happens?
i.e. the bike needs EITHER
a) Bike in Neutral - side-stand in either position
b) Bike in gear - side-stand must be up.

Also, diode only affects ability to start - has no effect on ability to run.
