2004 ford f150 charging system
has anybody have any issuse with the charging system light staying on after you have changed the alternator.
Story - the factory original alternator went out last friday night, on saturday replaced the alternator. voltage and battery check out fine charge light still on. replaced the alternator thinking that the one i purchased was bad off of the shelf. charge light still on. took to mechanic he checked the battery and alternator no issuse that he could find. charge light still on. took it to dealer no. 1 he said that the connector on the wiring harness at the alternator was bad and replaced it. charge light still on told me not to worry about it the system is fine. the response pissed me off took the truck to my local mechanic he went through the truck looking for shorts or blown fuses. He found nothing wrong he thought that maybe the pcm was bad and told me to take it to the dealer and have him flash the pcm to see if that would fix the problem. so off i go to dealer no. 2 - he flashes the pcm, this does not fix the problem. he says that the alternator that I put on is the wrong alternator. I don't think that is the problem but agree to let them put a new motorcraft on the truck to see if that fixes the problem (both of the alternators that I have put are motorcraft). low and behold this didn't fix the problem.
has anybody else had this problem? I am at my witts end on this. the NHTSA has 3 tsb's regarding the charging system and the indicator light on the dash. the only thing they show in the files are a summary no description of how to fix the problem. ford does not reference these three tsb's in any of the sites that I or the dealers or mechanics can access.
does anybody have a solution?
