Troubleshooting Guide
for Zone Irrigation Systems
This Troubleshooting Guide will assist you in the location of
fault in an irrigation control system related to power supply
or valve control wires. There are corresponding instructions
on how to use the test tool to accomplish steps that require
their use.
Step 1 Make sure the master water supply is turned on.
Step 2 Make sure any shut-off devices, such as a rain
Step 3 Turn the controller on and sequence the clock
Step 4 Make a list of all of the stations that are not
Step 5 Turn the controller off to test the resistance at
Keep in mind the water supply may be controlled
by either a manual or electric master valve.

through the different stations. If nothing is working,
skip to Step 6. If some of the stations are working,
proceed to Step 4. If all of the stations are working, then you don’t have any troubleshooting to do
at the controller.
functioning properly. Measure the output voltage
for each station using a Multi-Meter (Rain Bird
Model TI-DM200, TI-DM400 or TI-DSA500) and
the instructions provided. See Page 8 of this guide.
If the power is in range at every station (24-28
VAC ), proceed to Step 5. If the power is correct
when you test some stations, but not others, you
may need to have your controller repaired. Take
your controller to an authorized distributor.
each station. Use the following table to diagnose
the problem that each station may have.
0-5 ohms Fully Shorted Solenoid
8-20 ohms Shorted Solenoid or Multiple Valves
20-60 ohms Normal
> 60 ohms Bad Connection, Splices, Nicked
Wires, Open Solenoid or Broken Wire

Step 5 (Continued from previous page)
Step 6 Turn the controller off and remove the cover.
Step 7 Check the 120 V power being supplied to the
Step 8 Check the output of the transformer supplying
Use the instructions provided to test any valves
(or solenoids or wires) on the stations with faulty
resistance measurements (Page 9 of this guide).
A Rain Bird Tone and Probe Kit (Model TI-TPK)
or a Rain Bird Wire Sorter (Model TI-WS6) can
be helpful in locating broken wires and diagnosing
your system. The "snap-around" feature of
Rain Bird’s Model TI-DSA500 Multi-Meter allows
you to check the current of field wiring without
disconnecting it (Page 11 of this guide).
Check the fuse using a Multi-Meter (Rain Bird
Model TI-DM200, TI-DM460 or TI-DSA500) and
the instructions provided (Page 6 of this guide). If
the fuse is good, proceed to Step 7. If the fuse is
bad, replace it and start again at Step 3.
controller according to the instructions provided
(Page 5 of this guide). If the 120 V power is
in range (105-129 VAC), proceed to Step 8.
If the power is out of range, have an electrician
troubleshoot the wiring to the controller. Once
the 120 V power has been restored, start again
at Step 3.
power to your controller according to the instructions
provided with your Multi-Meter (Page 6 of this
guide). If the transformer’s power output is in
range (24-28 VAC), you may need to have your
controller repaired. If the transformer’s output is
out of range, you may have a bad transformer.
