about a month ago my electrical system started getting screwy. The car would be hard to start after it's been sitting for several hours. at first I attributed it to the cold. soon after I got my alternator replaced by the recal. Now the car is getting progressively worse. the lights dim like never before when I play my music, and today my battery dies over night for no reason. any suggestions? could it be the battery?

 

if they alternator is good, and u may want to test it, then more than likely its your battery. just take is somewhere and have them test it for free

 

get the battery tested.
