Pump Cycling: Check Controller Output to Pump Relay

Pump cycles after tank & solenoid replacement. Check if pump wired to controller (PS/MV terminal). If yes, measure voltage there — should only have 24V when zone running. If constant 24V → controller fault. If no voltage but pump runs → relay stuck.
