Thanks for that info Dave, I hate to be the person dishing out
misinformation, I was however repeating what I was told at college, I just
could not remember the reason given, I guess I assumed that a lecturer would

forgot to connect after welding and drove a short way thought I was just
very lucky when the alternator still worked.
Thanks again.
Graham.
