Re: How much should it cost to replace an alternator on 96 Crownline?
There is no way anyone can tell you how long it's going to take because no one knows what engine you have or what the access is to the alternator. 10 minutes is a joke if you are expecting a shop to do it. it takes longer than 10 minutes to test run it after replacing the alternator.
A realistic number for a shop to R&R an alternator with reasonable access, then test run, would be an hours labor. Also expect the shop to make money on parts. They will not sell you an alternator for what you can buy one for.
