Hire GSXR on recovery truck in Eastbourne

Hire GSXR bike being recovered back to owner - battery wouldn't turn over the engine after only a coffee stop in sunny Eastbourne. Diagnosis: battery not charging. Of course the day's weather turned out to be warm sunshine.
Looks like I won't be getting to the Hastings May Day Run tomorrow as well as no ride today.
Thanks to both the recovery guys for their friendly assistance.
