Well considering the starter is only engaged and draws current straight from the battery for a second and a half and the alternator at that time isn´t spinning fast enough to do any charging at that time, I don´t se how the starer itself could destroy an alternator. However a severly coroded battery cable can kill analternator really quick as I learned on my Siter-in-laws Chevy (Pronounced Shity) S-10. I don´t know who you source of information is, but if it´s a parts store person, he might just be out to sell extra parts. Also MAKE DOUBLE SURE HE GIVES YOU THE RIGHT ALTERNATOR FOR YOUR CAR. I was going through an alternator a month until I double checked the aplication description on the computer screen and had the part number they were giving me listed as for a Non-A/C vehicle. So every time I´d turn on my A/C, which is everyday from March to November here in Phoenix, I was overloading my alternator cuz they gave me th wrong part number. I did however get really good at changing them out. If NASCAR had a pit crew position for alternator changer, I´d be their #1 choice
