Sprikler no go all zones

post by annetanch on Jun 29, 2024

Facts

I have measured voltage on zone - about 30 V I have measured coil resistance - OPEN (!) (should be over 20 ohms minimum )

I have short at “rain gauge input”.

I have turn “rain gauge off”

I suspect open ground since NONE of the zones work.

Yes , I have water…

Question

is sprinkler AC GROUND actually connected to physical ground somewhere ? or should it be ?
