Thanks for replying. It seems the problem has sorted itself out!?? It now switches off when engine has been turned off. Must be a dodgy connection somewhere. Keeping an eye on the header tank because I'm sure water was being lost. Might be a completely different problem.

WHEN IGNITION IS SWITCHED OFF, I CAN HEAR A BUZZING SOUND COMING FROM THE WATER PUMP AREA. THIS ALSO DRAINS THE BATTERY. I HAVE ALSO NOTICED THAT IT DRAINS THE WATER FROM THE HEADER TANK. HAS ANYONE ELSE HAD THIS PROBLEM? WOULD APPRECIATE ANY IDEAS. MANY THANKS GRAHAM
