It turns out that warning lights may actually mean something :-) I got left by the roadside. Again. But by miracle my friend Lars happened to drive by and notice my car, and me, already on a cold, long walk home. He picked me up from the darkness, so I got home :-) thank you!
Looks like the generator may have failed. Again, I only got maybe 15 kilometres after the warning lights came on.
I think I've gotten the generator replaced couple of times per year on part manufacturer's warranty for the last two years. I wish their warranty would cover getting some other manufacturer's generator ;-)
