I have replaced the Alternators on this vehicle four times in the past four years. The Auto Service that works on my vehicle each time has put in a Bosch Alternators. Any ideal why? The History on the Alternators for this vehicle is:

1. 12-10-2001
Alternator & Battery was replaced.

2. 1-30-2003
Alternator & three belts was replaced.

3. 11-18-2003
Alternator & EFI Temp. Sensor was replaced.

4. 6-24-04
Alternator is in for replacement.

Each time, an electronics check was run and they check out fine. Any suggestions on what could be causing these burnouts? Thanks!
