I just picked up a miller del 200 with serial number JB490078 I got it to run but am not receiving any power out of the outlets or electrode plugs. The welder sat outside for about 10 years. I cleaned up the brushes and checked the connections they seem to be fine. But I did find out that the last 2 slip rings closest to the front are grounding out. So I followed the wire #33 it goes to the r5 resistor then were it plugs into the resistor it has another wire #33 that grounds it out. Was wondering if that could be the cause of my problems, any help would be appreciated thanks. https://photos.app.goo.gl/yMF6HM5EM49iqQ6N7
