955i Speed Triple Starting Problem

Evening all,

My 2004 955i Speedy Triple is having starting problems.

Flick the ignition on hear fuel pump prime, hit the starterator button, she cranks over and.... nowt!

New battery fitted in September 16ah Mottobatt (yellow one) only been ridden once since then but has been on a trickle charger all winter.

Battery seems to be fully charged at 13v, drops to 12.6v when ignition turned on and then 11.2v during cranking.

Does this seen like a faulty battery? Will 11.2v be enough to fire it? Seems to crank reasonably fast. Lights are really dimming during cranking (virtually go out all together).

Read the fault codes and the only code showing was P1501 which was a short or open circuit which I was aware of and never stopped bike running before (speedo would work intermittently).

Thanks in advance guys.

 

I'm the only person I know with a bike and I've tried bumping it but she's a big old girl and I can't really get her going fast enough. Tried 2nd and just locked the wheel.. maybe try 3rd?
