    Relay help needed.

    Hi
    I`m attempting to wire a few components to provide a
    estop feature for my machine. I wired the NO momentary
    switch to the relay. When I push the start button I hear
    and see the relay contacts functioning. I then held the
    start and checked all the available contacts and I`m not
    getting any voltage readings. I haven`t added the momentary
    NC stop button to the relay as I am uncertain as to the
    wiring. Any help would be Greatly appreciated.

    bgolash:

    Your question is not complete. Where are you measuring voltage?

    The circuit diagram at woodsolutions appears to be accurate.

    As in any trouble shooting you proceed in a logical manner, in other words using an AC meter using the neutral as a reference logically start at the point you have 120ac, e.g. the fuse and proceed through the circuit at the point you would expect to see the path of the ac supply. If you have the circuit miss-wired then you will see the point of error and likely find another point that shows 120v where it shouldnt be.
    If you have the relay in a socket, it is easy to get the terminations mixed up if not carefull.
    Make sure you identify the common arm of the relay contacts.
