That sounds like my problem then, the not getting 12 volts constant part i mean. Am I looking buying and installing a new positive battery cable? Is there a valid shortcut?
I don't think Ford still used a fender mounted solenoid in 2001. If they still did it's located on the driver's side fender under the hood about 1/2 way between the firewall and the battery. My '97 has one. It's kind of round with 2 large lugs (like on the starter motor mounted solenoid). One of the lugs may have a protective rubber cover on it. Check for this before replacing the POS cable.
If you do have the fender mounted solenoid, check for voltage there too. One lug (I would presume the one with the rubber cover) should have 12 volts all the time. The other one only when the key is turned to START.
A solenoid is like a remote HD switch. It is used to transfer high AMP power using a low AMP (thin) wire. Once energized it uses an electro-magnet to close the high APM switch. If it does not work it's either not getting the signal to energize or it's bad.
