So, I decided to tackle a couple of more minor items. One of my fog
lights wasn't working. Check to see if there is power at the bulb. Sure
enough there is. Replace bulb. Now I've got two working fog lights.
Yea!

Water pump on the sink wasn't turning on. Check for power at the pump
(well connector above the water tank.) No power. Check at connector
before sink switch. Power. Hmmm.

Take sink switch apart, clean off corrosion. Put back together. Now I
get water at my sink. Yea!

Now I just have to change my oil and I'm ready for the season.
