I have a 03 Expedition EB and I have a intermitant problem: the battery light comes on, chimes, message center says check charging system. I have had it at the dealer twice, once for two days, they say Ford is aware of the problem but does not have a fix at present! This morning my wife drove about 10 miles round trip and she said it beeped and blinked all the way. HELP! UPDATE- Returned to dealer and they installed a new alternator, didn't help, still has problem. Today I bought a volt meter that plugged into the lighter outlet to see if the voltage was falling off when it started chiming, etc. It was not! The voltage is staying between 13.5 - 14. Any ideas? Maybe a shorted wire behind the dash, instrument cluster? I'll take it back to the dealer Monday, they are trying. Thanks for any suggestions.
