Ok.. I think both trains of thought are correct, though specifically in my case it looks like it was the battery. It eventually died yesterday and did not crank at all. I have it on the charger now though I used the hygrometer and it looks like one of the cells may be dead.

Time for a new battery if this cell does not resurrect... which I think it won't.

Thanks for all replies. The wing started coming up on start around two weeks ago so anyone who has this happen even after the manual wing reset till you hear a beep.... take it as a warning sign that your battery is struggling to keep charge.

Cheers and thanks
