2016 Thruxton. Won’t Crank Over, Just Clicks!

Thruxton 1200 won’t wake from winter hibernation.
Just a click when trying to crank it over.
I’ve jumped it from my car battery. Had the leads on bike battery, with car running for 25 minutes. Tried crank with jump leads still in place. Nowt!
Also took battery out to charge from the mains. Charger indicated already charged to ‘full’.
Tried to hot-wire, shorting the +ve & -ve terminals of the starter solenoid - nope!
Disconnected battery for 20 minutes for capacitors to lose charge & reset ECU(?).
Changed the starter solenoid today.
Still not a peep apart from the ever-present ‘click’
Help!

 

@Bolosun I checked the battery without ignition on: 12.7v
With ignition on it dropped to 11.6v and was falling….surface charge only(?).
Tried to jump it off a running car, 14.7v.
- still nothing but a click.

Tried to bump it. It did start on the second d attempt….a bit lumpy, but it has just awoken from winter slumber.

New battery ordered. Should arrive tomorrow.
! Strange that jumping it off the car didn’t solve it!

 

@joe mc donald New battery arrived late today.
Will fit it tomorrow and I’ll post any developments/changes.
I’ll check clutch, side-stand and starter motor connections…..
(Thanks!)

 

Yes. The bike dies successfully bump start.
‘Sticky starter motor’ - dies that always mean replacement?? (Eek!)

 

Yay! Great news, brought to you today by @Bolosun

 

So…. against all conventional wisdom I’ve just put a new battery in the bike and it’s just returned it to its normal function which I find incredibly hard to understand and even except!
Before this I tried a car battery. I tried jumpstarting off the running car. I’ve even tried to charge the previous battery and I was certain that the battery was not the root of the problem.
But as it turns out in this instance the battery is the source of all evil. I just now need to sort out why it’s misfiring on the right cylinder after I serviced it and have left the fuel in there all over the winter!!

I know it’s not the exciting and most technical of solutions to the problem, but I wanted to share it on the forum just to give something rather than only take from this team….

Just to conclude the sooty (and embarrassing) saga…..the new battery did solve the problem.
NB: Trying to hit-wire by shorting out the terminals if the starter solenoid didn’t work - as the bike’s brain is cleverer than mine, it interpreted it as an attempted theft. Leading to it getting its panties in a bunch and shutting down attempts to start on the button.
NB: Trying to provide electrons from a jump start didn’t give success either, surprisingly.

Bike is now running better than ever.
