Question
I have a Toro Turf Pro 6 controller; after a lightning storm it began flashing "FUSE" but does not indicate a particular valve/station.  How do I go about finding out what's wrong?  I have all Toro pro parts.

Answer
Hi Rob

Your Turf Pro controller will detect a short or an
excessive total electrical load, automatically
advancing to the next valve with scheduled run time.
When the cycle is over, the display flashes 揊US?br> and shows the valve number.
To test a valve:
1.Set the Function Switch to Run .
2.Turn the DIAL to the valve number you want to test.
3.Press the +/- Buttons to display one or two minutes of run time.
4.Press the Semi-Auto Manual Button to start. If the valve does not
begin to operate and the display flashes 揊US? that particular valve has
an electrical short, or other problem. The valve solenoid and wire
connections should be inspected.
5.To clear the display, press the + or - Button.
CAUTION: Do not test the valves by touching the wire ends to the
terminal screws. Serious controller damage may result.

If you don't get the valve # on the display check the valves selenoids, using a multimeter, set it to measure Ohms, put the black lead to the white wire and the red lead to the valve wire, you should get a reading between 20-60 Ohms if it is out of range replace the selenoid. Repeat this step for each valve selenoid.
