Well, to be perfectly fair, the rain sensing wipers failed a long time ago, and I had forgotten to post about it.

So, what's the best way for me to troubleshoot the charging system on this car?

Thanks for taking the time to work me through this, if I came across as somewhat snarky before, that was not my intent. I just reread my post, and realized that it may have come across with more "tone" than I had intended.
