Im working on an older rainbird controller. Turned the water on today and was setting up timer. Had to start from scratch. Must have lost power over the winter. Testing zones and notice that 2 4 and 6 all operate as intended but zones 1 3 5 and 7 all turn on only zone 1. Not sure what has happened. Any Ideas? Going to try a reset tomorrow and the customer is already thinking about a new timer anyway but it would be nice to have it running until shes ready to purchase a new one. Thanks in advance!
