Hi all. Have yet to find info on this, so here goes... Previous irrigation controller (ProC) intallation includes "extended" (spliced) wires between Hunter transformer and controller. This was apparently done to enable the transformer to be plugged into the 120 outlet in garage ceiling (power for gar door opener) as there is no 120 near controller. However, they extended only the 2 24V AC wires, but not the ground wire. This has resulted in a floating ground causing signal problems. Thought that I could simply add a ground, but when I talked to Hunter, they suggested they don't support or spec such a setup. Other than adding an AC outlet, any recommended solutions?
