I have 5 Zones on a Rainbird ESP-TM2 6- zone controller, professionally installed 4 years ago. 3 of the 5 zones (1,3,5) are not being triggered by the timer, Zones 4-5 are working.
- Panel is getting 38VAC, and non-working zones are getting the same voltage at the same time (even when only one is selected). In other words, when any of the non-working zones are turned on manually, all 3 (1,3,5) are registering 38volts.
- Multimeter Ohm continuity beep test (without removing wires from panel), the working zones beep, non-working zones don’t
- Swapped a working zone 3 wire with non-working zone 1 wire. Zone 1 now works, Zone 3 does not, so assuming it is not the panel
- The 3 non-working zone valves are physically located in the backyard, the working 2 are located in the front.
