Look for a bad (short-circuited) solenoid

Can you give us a make/model of the controller?

You may not have a fuse. It's just a warning. If you do have a fuse then you'll need to replace it.
Reset the controller. Just unplug it. Take out the back up battery. Run the stations until you see which numbered station causes the "fuse" warning.
Find that valve and disconnect one of the wires from the solenoid. Now run the controller again. If there's no warning change the solenoid as Boots suggested. If not it's a wiring issue.
