Battery light + Fuel/Water light blinking simultaneously - then continuously

[CTScott]

The symptoms definitely sound like a charging issue. The squeaking of the belt happening and then stopping may just be because of the temperature at the time or something getting on the belt, but a squeaking belt pretty much always mean a loose belt, and once they start squeaking they get glazed and really should be replaced.

Besides checking the belt, I would check the battery terminals to see if either is loose or has corrosion on it. The bumpy road could have rattled an already loose connection.
