I inherited a 2000 ES303 in 2014, The alternator had already been replaced when I got the car. I have since replaced the alternator three times and it has gone out again. The alternators I got were from Oreilly's and they go out just after the warranty expires. They are made in Mexico. I bought the last one in November 2016 and it is not working.. I put a new battery in the car also in November 2016 at the time of the last alternator.

Any suggestions?
