I had a problem with the altenator 1-2 weeks ago. It was in the shop for 1 week to get it fixed.

Here are the parts that they changed:
cause: internal failure
- Alternator removed+reinstalled (839 WP95)
- Remove and Install battery (839 WP95)
- Charge Battery
- Diagnosis

they added/changed
1 Gallon of Antifreeze
1 Baterry 110AH
1 Alternator

Does it look like the problem may occur due to the cold weather in Boston? I am pretty happy with the job though since they changed my baterry to a new one
