Battery drained, recharged now sets off an alarm and won't start the van. Any suggestions? we reset the fuse that is supposed to keep it from draining all the way.
Make sure you terminals are correctly and tightly secured it also sounds like it could be the voltage regulator.

If you have a multimeter with a 10 Amp range, you should try the following:
- Locate the master fuse box/center.
- Turn any electrical item off that you can.
- Set the meter on the (normally separate) 10 Amp scale; connect your leads to the meter.
- Detach the negative (ground) clamp of the battery, fasten (your option how) the positive meter lead to the removed negative cable, the negative meter lead to the negative battery terminal. If the meter instantly pegs, remove the leads, the range is too low and these are never fused in the meter so will do damage to the meter if left connected.
(If you have no cheap digital multimeter, these can be had for <$20 US at auto parts stores or electronic shops such as Radio Shack. Look for the 10 amp range but most have it.)
If there is (and there will be) an in-range (not pegged) measurable current draw, start pulling one fuse and replacing it going through them all until you see a noticeable drop in the indicated current.
Once you have isolated the guilty circuit, then you can start seeking the cause of the drain.
The problem you describe is, in fact, a common one when the (albeit new) alternator has a defective diode that represents a permanent load on the battery.
It wouldn't be the first 'rebuilt' alternator to have not been thoroughly tested before it was boxed and sold.

When the battery is disconnected and replaced and when the battery is drained and then recharged, the anti-theft device in your car was activated.
Refer to your Manual to arm and disarm the anti-theft device, it should reset
If this does not work using the remote, try locking and unlocking the driver side door with the key and IMMEDIATELY START the car.

There is an alternator fuse located on the positive battery clamp or in the fuse block under the hood. if it is part of the positive battery clamp it is a dealer only part and will run $10 to 20 dollars. If it is in the fuse block you should be able to get one at the auto store and modify it to slide in easily. Get a flash light and check all of your fuses carefully. The blown fuse may be hard to spot. The design of the car lets the battery go dead with out even turning on the charge light on the dash to let you know you are not charging the battery.
