    Default This is a scheamatic for PIC/RELAY/SOLENOID connection

    it is not clear how you have connected the two relays to the solenoid
    Attached is a schematic as to how I am connecting the PIC outputs to the RELAYS to control the SOLENOID via its RED and BLACK wires. This shoulld permit switching of the polarity to the RED BLACK wires depending on which control pin is active??
    I guess if I follow the steps from Melanie's email I can do this without inserting the 2XOR and Dual 2AND gates in between the two PIC control pins and the two relay coils??????
