All posts are valid checks. One more to check is the brushes on the alternator. The brushes are integral to the voltage regulator. It is attached to the back of the alternator by two screws. It's about 3/4x2". Disconect the neg batt cable and remove the two screws and remove the regulator/brush pack. The brushes should protrude about 3/4" from the regulator body when new. If the length of the brushes is dramatically different or they are both extremely short, replace the regulator. They can be found at auto parts stores for 20-40 dollars. About 50 at the dealer.
