The car is a 2004 and you don't have the owner's manual? Anyway, the
battery light coming indicates an undercharging condition, usually
caused by a dying alternator or/and battery. Invest in a digital
Volt-Ohm-Meter and check alternator output at idle, at the battery
posts, where it should be a MINIMUM of 13.4 volts while idling, and at
least 12.5 volts with everything shut off.
Thanks to all. Yes I do have a manual - it says take it to your nearest
Ford dealer. And apologies to the Krusty Old Geezer. I'd taken the
"smartass - DEAL with it" stuff as part of his reply. I'll get my coat.
