Drove through some large puddles because Detroit floods with any rain. None too deep and never went quickly. Battery light came, car still got me to work.
At lunch I checked the battery out with a voltage meter. 12 volts, turn the car on and still 12 volts. In the shop now, who wants to guess what’s wrong/how much this will cost?
EDIT: Alternator for $550 with labor. Might be getting ripped off but it’ll be done around 5pm and I don’t know if I could make it the 45 minutes home to change it myself.
