I hope I'm allowed to post this here... If not please disregard and know that I'm sorry.
My 2004 Mercury Monterey broke down last night (all electronics shut off and it came to a sputtering halt) due to a bad alternator. I replaced it this morning and, after a jump, the car has run fine all day (drove for about 40 minutes). However, the battery light/check charging system light is still coming on while driving. I'm wondering if this could be because the battery is still low and is recharging, or if there is still another problem with the alternator, wiring, etc. Maybe the bad alternator ruined the battery? Anyway, any thoughts are appreciated.
