This drains the battery!!! So they know they should go down and the motor is trying to put them down without success. Nothing seems to be blocking the mechanism and the manual solution suggested on 1/22/09 works perfectly but will be hard to do in the dark!!!

It is likely neither the starter nor solenoid. Detecting what is draining power is a pain, start with pulling all the fuses, and see if it's still draining your power.
If so, then it's something that's powered without a fuse (unlikely)
If not, then put fuses in one at a time until the drain is back. Now you know which circuit has the problem. Investigate that.
Loosing power is a totally different issue. You get a "check engine" light? Get the code read.
As with any battery drain, you would pull the fuses and disconnect the major circuits while watching a test light or meter that is showing the drain. When you find the circuit in question the light goes off. Then the fun begins trying to find the source of the drain. In your case you may want to start with disconnecting the radio. You may need a shop manual to get the wiring diagrams.
Where both rebuilt alternators any good & retested at store?
Your explaining a constant voltage drop, once the battery is hooked up.
How about the ignition switch? Does that have anything to do with the regulator control in alternator?
You haven't said you have 14 plus volts with motor running,so basically you don't have an alternator charging your new battery & the ignition currant, even without the lights on, is running down the battery
All I said is what you already know
I'm is missing something?
Don't unhook any battery cables with the motor running,were not living in the 1960's
Those type tests will ruin many things on newer vehicles, than yours,loose that practice & also avoid jump starting any vehicle from 1996 on
HAVE BATTERY RECHARGED OR VECHICLE JUMP START.WITH VECHICLE RUNNING MAKE SURE ALTERNATOR IS CHARGING THE BATTERY.ALTERNATOR OUT PUT AT BATTERY SHOULD BE 13.5 - 14.5 VOLTS.IF NOT CHECK ALTERNATOR FUSE.CHECK ALTERNATOR + BATTERY FEED WIRE AND VOLTAGE REGULATOR WIRES MAKE SURE NONE OF WIRES LOOSE BROKEN OR DISCONNECTED.IF ALL IS GOOD AND ALTERNATOR OUT PUT LOW ALTERNATOR FAULTY.IF ALTERNATOR VOLTAGE OUT PUT OKAY. YOUR BATTERY DRAIN PROBLEM COULD BE FAULTY AC HEATER BLOWER MOTOR RELAY.CHECK INSIDE CAR WITH THE IGNITION SWITCH OFF.MAKE SURE RADIO TURN OFF.INTERIOR LIGHTS TURN OFF.HEAD LIGHTS TURN OFF.LISTEN FOR ANY NOISES LIKE BLOWER MOTOR RUNNING, OR FAULTY DOOR LOCK SOLENOID CLICKING NOISE.IF EVERY THING SO FAR OKAY.OTHER POSSIBLE CAUSES BATTERY DRAINING COULD BE FAULTY ALTERNATOR,FAULTY STARTER SOLENOID CONTACTS SHORTING OUT.THE PCM COULD DRAIN BATTERY IF FAULTY.THE NEW BATTERY COULD BE DEFECTIVE.
check for any lights staying at night, dome lights, sun visor lights for vanity mirror, glove box lights and so on, also have the battery tested, a bad cell can cause the battetry to run itself low, any Autozone or Kragen will test the battery for free.
Battery is dead, replace it. Just went through it on my Windstar sport- that's how Fords are supposed to operate if the battery is non functional. (click click click gauges up and down up and down up and down... yeah that's the problem no doubts.)
did it quit making the noise when you lightly push down on the trunk? most people slam these trunks and your not suppose to you are only to put light pressure on them and they pull it closed theirself.. you might check your relays under the hood and look in the box lid to see which one it is.. if this is not the problem you might have to replace the motor to the latch .. you might check with a test light to see if there is power to the motor first though .. thanks and holler if you have more Jerry .
It's hard to know what the previous owner had in mind by installing a kill switch on the fuel pump. Was this to overcome some wiring problem?
You say the battery "suddenly started draining". can you recall anything else that might have happened about that time that might be associated with the "sudden battery drain"?
If you disconnect the ground battery lead can you see any small sparks when you touch the lead to the battery terminal? If you can detect any, this indicates something is drawing current from the battery. Then remove one fuse at a time and check the presence of sparks again. maybe you might luck out and find which circuit (fuse) is causing the current drain.At least you might be able to isolate the problem
The new sealed batteries fail without any warning, drive to the store, come back out the battery is dead, the other issues you have are caused by low system voltage, replace the battery and all should be well.
