The drive belt appeared to have moved inboard a bit over time and was talking a lil more than it should be so while the panels were removed I noted the battery, and that I have not done anything with it since new. I was pleasantly surprised that removing the battery wasn't as difficult as I had imagined, but once removed I found the terminals to be very corroded and the water levels very low. So, I cleaned everything up, filled the battery with water, and the re-installation went fairly smoothly, again, pleasantly surprised. So, this is mostly just a small prod if you have not checked the battery in a while, you may want to just give it a looksie?
