relay clicking when connecting battery?

Just curious if any of you with the 2.8 have any relays click when you connect/disconnect the battery? A relay seems to be clicking when connecting the battery back up (I think it is the MAF.....front right by airbox) and I don't think this is normal. Any of you have this??

thanks.

THat is a different setup though so things could be different. Are you referring to when turning the key on though before starting rather than disconnecting the battery? Because clicking is definitely normal in that case.

Unless I am missing something, I don't think a relay should always be engaged when the car is off as it will be a current draw.

i get that too, never bothered to check into what it is, because ive heard it on lots of other kinds of cars as well. cant see why its not normal, although that does bring up a good question as to what it is and why?
