I am hooking up a 230 volt pump 2 speed waterway pump. I have 4 wires 2 hot (black and red) one neutral and one ground. I have the black on the high speed the red on low speed terminal and the common on the neutral and the ground Green on the ground screw. The problem I am having is the with the low speed when I turn the manual switch I installed on low the pump starts but I hear a clicking sound. when I turn the switch to high pump works great. I have switched out pumps and switched the two hot's but still have the same problem any help would be appreciated???? Going nuts with this. I have a 1.5 Hp pump with two speeds 230 volt. the Black is going to L1, the common is going to L2 the red is going to A and the ground to the gorung.
