Hello, I have an old regency 250 that has worked well for quite some time. Recently it was giving me problems by not providing gas flow. I talked to a few guys and they said it was probably my relay, so I went ahead and bought a new one. Before I got the chance to install it someone unhooked all the wires to that relay and did not mark which pins they were supposed to go to. Now I have no clue where any of the wires go on the relay. about the relay it says CR 1 so I am assuming it is the control relay? The wires are numbered 38, 37, 36, 34, and 30. I am not very experienced working on welders so any help would be greatly appreciated. Thank you
