the charge light came on,checked not charging,replaced alternator,charging,but discharges battery overnight,fitted another new alternator,same problem,anyone with any ideas ?
Sounds lo me like you've wired the new alternator incorrectly or there is a fault with the battery.

sounds like something draining battery-is it a van,rear interior light is going off isnt it? there could be a relay stuck on,check to see if any feel hot ,as though they could be stuck on.
