1998 Ford Crown Victoria Repair Question
Ford Crown Victoria Battery Problem
That's an option not many other people got! Check if the "Battery" light on the dash is turning off. That is is the turn-on circuit for the built-in voltage regulator. If the light is on, you have an ignition switch problem. If it is off, I suspect the voltage regulator is defective. One wire to it, (typically yellow) will have 12 volts all the time so there is a power source there if there's an internal defect.
