I keep blowing fuses on my rain bird esp-8tm and then it reverts back to Pwr off
Hi @menyv , Does the fuse blow immediately or when you start the controller to begin a watering program? If immediately then there is a problem in the controller. If only when starting a watering program then one of the stations in the controller or one of the solenoids (or the pump start relay / master valve), may be faulty. You would then have to find out which one. Disconnect all the stations solenoid wires (not their common wire connection) and the pump start/master valve wire (if you have one) If you have a DMM (digital multimeter) you could measure between each solenoid wire (and pump /master valve) and the common point (earth) and check the resistance to make sure that it is not short circuit. If all the solenoids test OK then connect one solenoid only, to each station in turn and then test each station and check if the fuse blows. If you don’t have a meter then if you have enough fuses connect one solenoid wire to each station in turn and check if the fuse blows. If it works for all the stations, then try the next solenoid wire on one station only as they have been proved to be OK and then the next solenoid wire etc until the fuse blows.
