After reading 20 pages of this thread regarding replacing alternators: http://www.peachparts.com/shopforum/diesel-discussion/93569-alternator-115-amp-bosch-al129x-works-123s-20.html

I've decided to spend the extra coin and replace the alt and vr in one move, upgrade the wiring along the way to 4 awg and probably copper terminals - whatever the local store has.

Since this car will be used in the winter I figure it's step towards keeping the battery in optimal condition.

My hope is that replacing all this will solve my interior warning lights being on, but at the very least it will solve the battery charging issue.
