Thanks for the replies. The battery is not that old, but I'll have it checked.
The alternator is two years old and the starter is also new.
Has Bernie suggested I have clocks running, a screen that indicates unlocked doors low coolent etc, etc, also a dash light which is always on for the alarm system.
So it may be a drain problem. I'll charge it and when not in use I'll disconect it.
Thanks again
