1999 F150 new battery not holding charge

I would appreciate some help understanding a recent issue with my truck if anyone can help.
About 7 weeks ago i started hearing clicking sounds UNDER INSTRUMENT CLUSTER NEAR STEERING COLUMN when i turned off the ignition. This progressed to clacking sounds from the relays.Itook it to Ford and they had me take the battery back and get a new one underwarranty because it would not charge So i did and the relays were swaped out fro new ones. worked for a couple of days until the clicking after turning off ignition started to come back
Last friday i went to start the truck and nothing happened but the relays started chattering again. I eventually boosted the battery and was able to drive it for awhile. The next morning the same thing happened I COULDN'T BOOST FROM ANOTHER BATTERY SO I USED A BOOSTER PACK AND GOT IT TO START AND DROPPED IT OFF TO THE DEALER OVER THE WEEKEND. So, I AM WONDERING IF SOMETHING IS DRAINING THE BATTERY(Sorry about the cap locks) or if some other function of the vehicle might be at fault? My laymans thought is that there is a short somewhere which is sapping the battery. Any thoughts?

Yup--and check it at revs, not just idle.

I had one go on one of the e350 work trucks, and while it put out 12.4 at idle, that dropped to 9v by the time the engine was up to driving speed.
