how much do alternators usually costs
Report Abuse. I would estimate the cost of alternator between 40 and 60 dollars. Most shops want get 60 dollars an hour, should not take more than 1 hour to instal. You should call 4 different shops for exact figures and cost. You will get 4 different ansears.They should be all very close in price of each other.eport Abuse.
