Hey so I’m having problems with my civic I just replaced the alternator and it was fine for a bit but I was on the freeway and the dash lights started to flicker and my car began to jerk has anyone had this problem before.

 

Is the belt and all electrical connections properly tightened ? The alternator could be junk out of the box , if the original was mitsibishi then I would have got one from the dealer they won't give a core charge if it's not ., it'll cost you but it's peace of mind
