Not that I'm an expert, but I believe its one of those generic "power problem" errors. Fucked battery, loose connector, bad connection etc.

Just to clarify, was that Harley Assist that were too busy to show up? Were you in the sticks?

Thanks. That is strange. Hope I never need it but if I do, I'm hoping the 'assist' part is more than a chat on the phone, though sometimes that could be all that's needed...

I will stop hijacking your useful thread now. Cheers.
