Customer Question

Hi,
I have a Onan Cummins MDKBL genset on my boat. I am replacing the pressure switch 0309-0717. There are 2 electrical terminals on it - one labelled "C" and one labelled "NC". There are 2 electrical wires to attach to it - one labelled "gnd" on the wire casing and the other presumably live. Does "gnd" connect to the "C" terminal or the "NC" terminal with the other live wire going on the remaining terminal?
Thanks,
Jeff
