MEP,..... I was not quoting you, to say that the information you stated was incorrect. I was simply stating that we need more information about what equipment he has, as there are many different ways of building a car wash. I asked earlier if he had a rotary switch, because he could have and piezo buttons on a ginsan coinbox.
I believe it would be beneficial to know whether he has a 2 stack, or 3 stack rotary switch, and whether he pressure feeds or gravity feeds for high pressure. (relays in the control box) Is the pump just not coming on, and solenoids are opening, or is the voltage not making from thos positions, to the control box.( bad rotary switch)
Could it be that he had a bad rotary switch that he recently rewired incorrectly???? ( see other post)
I truly apologize if I upset you MEP, but this is one reason why I don't like to post very often, because YOU take things too personally, and YOU seem to know everything.
