My 1200 Explorer (2012) Won't Start

Batteries don’t work so we in cold weather so my immediate suspicion is that it has fallen below the minimum level demanded by the ECU. If it is the original battery it will definitely be ‘tired’. Charge it and see.

 

Go for the obvious first
Kill switch
It’s a Triumph so the clutch needs to be pulled in
Side stand switch

 

Aside from Dilligaf’s entirely sensible suggestions (wow!) the answer is ‘no’. There can be enough juice to illuminate everything but if the ECU detects insufficient power to turn over the motor strongly then it will not react to the starter button.
If you compare a (necessarily small) bike battery with what you would find in a 1200cc car you will appreciate how much is being asked of it and how little reserve capacity it has. Most of us have smart chargers (Ctek/Optimate etc.,) semi permanently plugged in to avoid problems and maximise battery life.
