Question
I have a ESP-16-LX+ and the display shows "Fuse".  How do I find the circuit fault that is causing the problem?

Answer
Hey Royce, what you need to do is start with zone(valve) #1 and turn it on manually. If the circuit is bad,(either the wiring or the solenoid) as soon as this valve goes on, it should say "fuse". Continue through all the zones, until the zone(valve) # you want tells you "fuse". Once you find out the valve that is giving you problems, then find it in the field and check or replace the solenoid, and see if that is what is causing the problem. Usually it is the solenoid that shorts out, but sometimes it could be the wiring going out to the valves.Good luck and have a great day.
