Why did my check engine light and warning chime go off after I had the alternator replaced?
Just had the alternator replaced on a Lincoln Town Car. Drove it home and the check engine light came on and a chime kept going off, five times slowly, then a rest and repeat for three times. Then a longer rest and it started chiming again. I took it back to the shop the next day, but it drove just fine, and they couldn't find anything on the OBD. I have been checking other forms, and it seems like a low charge on the battery may be the problem. Any thoughts?
