The worrying 'battery not charging' light blinked on last weekend and it took some scrambling to debug the issue. Many thanks to the previous owner for continuing to be very patient with all my questions. I know the belt drives the water pump as well, but was continuing to run cool. A little prodding revealed the belt was tight, but not tight enough to spin the small pulley of the new alternator.
Loosened the alternator, and swung it further out on the custom adjustment arm built to hold it on the frame. Also added a new SS bolt long enough to put on a lock washer and nut out the other side of the alternator bracket. For insurance, I added a bolt on the mounting arm immediately below to keep it from vibrating down the arm like what I believe happened this time.
Anette's dad was a huge help as well, and thank to him, I have a big-ass pry bar to make the adjustment myself if I need too again.
