So checked a few things...

1. Put the charger on the bike, 24 hours later battery is at 13.2v and Bike started normally
2. With Bike running, checked the voltage going to the battery, 14.4v so all normal.
3. Left the charger off for 24 hours (and unplugged the tracker) to see if the battery was dying or being drawn down, voltage at 13.2v so that seems normal
4. Measured the voltage drop when hitting the starter, dropped to about 10.5v until it started (almost immediately) the returned to normal 13.2v when turned off. I’m leaded to believe that might be a touch low.
5. Will check the charger tomorrow

Conclusion? Fooked if I know...

That being said, the circumstances where a little unusual... queuing to park, Bike got to 106-107 degrees so fans kicked in, would that cause a big drain enough to stop it starting?
