Any old promotor drivers around

I was in touch with Gavin McArdle a few days ago and he related an incident that happened back in 76 on the Yugo/Austrian border. I have copied the short anecdote here wondering if the Promotor driver could have been correct in his assumption that his Scania had a 12v electrical system. What do you think? My view is its either a wind up or it was Wellie Ward at it again!

Gavin ment Sentilj, the Jugo side of course.
