Make a list of all of the stations that are not 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 9 of this guide. - Page 4 (or solenoids or wires) on the stations with faulty resistance measurements (Page 10 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.
