Q: alternator problem

asked by on November 13, 2016

the alternator went up and every time we put in a new one it keeps frying, we bought the car used & it had a truck battery in it. I think the guy selling the car put the larger battery in so the car would run when we took it for a test drive. It's at car repair shop right now but the mechanic can't figure out why the new alternator is frying??? Any advice???
