Battery drain traced to central locking...

[Peter Schulz]

Folks:

Thanks for the feedback...

For those of you with "perpetually running" central locking 
pumps,  should I assume that they were only running when the doors were locked?

Haven't had the time to dig into this with other priorities, but I 
think Eric may be on to something...

thanks all!
