Don't recall if this has been posted here...anyway a heads up: http://kdvr.com/2017/02/05/fire-under-the-hood-defective-heavy-duty-ram-truck-alternators/
There are a small hand full of vendors that supply alternators to the auto industry! A manufacturer like RAM does NOT make their own alternator. The same alternator could be on other vehicles besides RAM's.
As vehicles has become more electrically complex alternator size has increased greatly. A 180 or 200 amp alternator is pushing a lot of current at times.
