ultramount pc board questions
15 Year old ultramount. Is it possible for the hand held controller to be sending signals to the motor but not the coils? Cleaned can, manifold, pump and all relief valves and replaced coils and switches. Relay is good, cleaned all wire connections, grounds etc. sprayed with die-electric spray too. Pump is fine and motor is fine too. Coils activate switches on bench and motor comes on when I press a control but I get no command to the coils??? Really starting to pull my hair out on this one, and I can't afford to loose any more of that. Could the pc board do that???
