Does it still go flat with "Just" starter and alternator connected, because starter terminal is usually the connection for a whole load of other circuits.
Disconnect the earth lead tonight and see if the Battery stays up with everything disconnected, then if it does tay up OK get an ammeter, like a analogue one say up to 5 amp and stick a couple of crocodile clip on it and place it between battery and the earth wire, if it shows less than an amp get a digital ammeter and see what the drain is and start disconnecting things Alternator first, until the amps drop to 0 or a few milliamps for the clock and radio etc, I guess you lost the radio code already. Most likely culprit Faulty Alternator, next Glovebox light, underbonnet light which come back on as the lid goes that last tiny bit to being closed. It can be a very long and tedious task hunting power drain.

2 possibilities:
1. Disconnect the earth cable from the negatvie terminal of the so-call "new" battery. Leaving it over the night, if it still don't hold charge - Replace the battery
2. If the battery is okay. There are a short circuit in your van electrical system, not serious enough to burn out the system but some where is draining off the battery power! Get an auto electrician to check it out.

If you disconnected the Ground (black) and it still drained, it means one of two things. You did not have a proper charge on it before or you have a bad battery. You may test the battery at most automotive stores, or if you have a voltmeter. It should read over +12VDC with the engine off: with it cranked, the alternator should make the battery read approx +13.5VDC. You may also check each cell of the battery with the voltmeter if it has removable caps on top. Clean top of battery and remove caps, Each cell should be +2VDC. Each additional cell will add +2VDC. Meaning Cell 2 will be 4VDC, cell 3 =+6VDC, etc....If you have a battery charger, all the better for testing after a thorough charge.

Get hold of your ford dealer. This problem came to light with the Lincoln nav's when none would start in the dealer's lots. The problem is the cruise control module staying live with the key off, draining the battery overnight. In some cases, the drain could cause an overheat of the module causing a fire. There is a recall now on all ford vehicles to replace the defective parts.

Get the battery tested it may have a dead cell or two
If you have a new battery it's time to get an auto electrician on the job. There must be a short somewhere that draining it

Make sure there is no interior light being left on. I had the same problem some time back until I discovered a small light in the back that had its own switch which was left on. I didn`t even know it was there. Turned it off and the problem went away. Simple but it killed one battery in the process.
