alternator for sure......the problem with our cars is that the voltage regulation is controlled by the PCM. Hope that it is just the alternator, but if the odometer is showing messed up things, it may be the pcm. When my PCM died, the odometer, gauges and lights would all die, but the car would still run. It would tell the alternator to send out higher than normal voltage which caused me to go through alternators faster than oil changes. I went through 2 batteries, 5 alternators (including stock), 1 set of battery cables and a pcm. Best thing to do if you can is to test the alternator while the car is running. (if anyone needs and alternator changed on the side of the road i can do it with 2 screwdrivers and a socket wrench lol :D)

o and dont worry about the PCM, it should be covered under the Ford emission control component warranty (or somehting like that) if that turns out to be the problem. I believe it is valid 8 years from in use date.
